AIYIMA T9 PRO 200W Bluetooth Amplifier HiFi Digital Class D Power Amp 2.0/2.1 Channel Vacuum Tube DAC Amp with VU Meter & Bass Treble Bluetooth 5.2 Coaxial Optical PC-USB inputs (AIYIMA T9 PRO)

I have had this little amp for many months. It’s fantastic and a great value. For a while, I did feel as if I wanted it to get better volume without maxing , but I was able to remedy this. After looking everywhere to see if I can plug this into the A07 max and basically use it as a pre amp, i decided to try it myself. I also got the upgraded power supply for the A07. (Makes a huge difference). I also upgraded the tubes in the T9 pro with the $25 riverstone audio pair from amazon. IT IS WORTH IT. Essentially, my T9 pro is being used as a pre amp with tone control and DAC into the A07 with upgraded power supply. This opened up the sound stage, gives me the volume and adjustability I wanted, and looks cool with a small form factor. I also have the x2 pre amp for my turntable with upgraded tubes. All in all for a pre amp, upgraded tubes, upgraded power supply, t9 pro and A07 max, you have a full set up that you can have a turntable attached and television. It worked great with my a/v switcher too. At one point, i had my TV, a cassette deck, and my phono pre amp all hooked into this thing running through Kef q350 speakers. it is extremely fun messing with all of the items like a lego set. THE SOUND -Turntable Get an external pre amp. The sound is crisp, and clear. Beyond impressive for its price point. It is a little thin on the bottom mid range and upper mid range, but the dynamics are awesome and you can hear the instruments in the music. I test everything with “Rhiannon” from Fleetwood mac, it really sounded awesome. I do not find that it adds to much distortion or clipping even when volume is maxed. -TV Through the optical table, it sounds great. I sometimes like just playing my playstation through a simple 2 channel set up in my small media room. It’s easy to switch from the remote and adjust the treb and bass as needed while sitting in the couch. -BLUETOOTH My 1 knock. The bluetooth on this thing sucks. The connection is fine and if you just have background listening it’s whatever. But it is VERY thin sounding. Still a great feature to have. I think you would be better set getting a blue tooth adapter. OVERALL Awesome little amp with great sound and looks. Sounds even better when paired with A07 max and upgraded power supply. For the average listener, so worth it. I mainly listen to my music on a vintage pioneer amp, but I still put this on regularly. For someone starting off on a vinyl or hifi journey, especially with a tendency to hyper focus, save and get higher end equipment. You WILL keep adding little parts to this that will rack up to be the same as just getting a few mid range pieces.

As an experienced semi-audiophile person, this amp has excellent sound quality. I have been the owner of multiple amp and speaker systems from the 70's until now. Several things make this unit standout ... namely the sound quality, build and small size of the amp. The tubes look great and of course help give the audio good quality. I hear a slight amount of reverb on some music but cant quite put my finger on it. There is an excellent video on Youtube about the construction and testing these go thru. The remote is nicely functional, no non-working buttons and simple to figure out. I will test and compare with a vintage Pioneer SX1080 as soon as I can. Currently paired with some smaller JBL bookshelf speakers with about a 6 inch woofer (I'll update with the model number asap) . Good speakers will really sing with this amp. If you buy one of these and it doesn't sound good, think about upgrading your speakers. Bass is truly adequate but I think the high end could be a bit better. I will test with some Bose-901's, Dayton Audio B652's and some old Radio Shack Mach 1's for giggles. I steam Amazon music via small tablet using Bluetooth. That has been working and sounds fine but I do hear a relay click from the amp at odd times when there is no music playing. That has been noted on the T9 also -- not a huge problem but slightly annoying since the amp is close to my listening chair. A nice FM radio and another set of inputs would be icing on the cake. I'm not interested in changing the tubes but may shop for some spares as I have no idea how long they will last but with a low heater voltage and the mil spec, I would think they will last a long time. Updates to come, so far very good, I'm impressed and happy with the purchase. update - reverb was coming from a program I use to tweak the sound from my test tablet. JBL - older Northridge E Series E30 -- the current home for the amp. A great match, on the floor for now- will experiment with some speaker stands latter) . This setup got me back into truly "listening" to music again. I would like a hair amount more of high end but love this setup. Fantastic off center imaging. Starts clipping at about 85. 901's - (with out the EQ) - Best I've heard these speakers sound yet. Not as efficient and had to play the amp at higher volume to get descent sound volume but also sounded great. The amp played at louder settings with out clipping ... This was the best match up for the loudest DB's. I tried my old 301's but they didnt sound near as good but I didnt have time to tweak. But again .. it drove them just fine. Mach 1's - I've replaced the 15's (I forget with what) but they totally brought out the tube "warmth". No muddling or over powered bass. If I had room in my listening room, this would be my go to speaker. Clipping before they got too loud . Dayton Audio B652-- 6.5 inch woofer holds it own. I switched to them after listening to the Mach 1's and it was like night and day bass wise lol. Still pretty good but the JBL's have them easily beat. Very nice image separation and nice high end. Very fun playing this with ANY speaker. If you want LOUD, this is not your amp. But if you'd rather have 35 or so watts of great sound. Check this amp out. I'll compare the Pioneer soon. I suspect it will keep neck and neck until the power goes past the T9's abilities. VS Pioneer sx1080 - Dixie cup to Stanley ... the bigger receiver just plain has more power. The Pioneer easily sounds better at low volume levels with better overall tone but its not a fair comparison honestly but it was fun to compare the the same speakers ( some old Athena tower speakers). The T9 pro still sounded great though. Riverstone5654 tube update - slight increase in low end and channel separation. The Riverstone does a great job of packaging and documenting. I hear more detail and like the result. Seems worthwhile, but i cant see spending any more money on this unit. Hooked up a DVD player and connected it via the digital co-ax port. I have not used the optical port yet. That portion of the amp also works flawlessly and sounds great.

I've hooked up the T9 Pro to a pair of Polk R500 speakers. I'm satisfied as a non-audiophile. Mostly heard about the original T9 via cheapaudioman and a handful of other channels. Then I was pleasantly surprised when I found out that Aiyima just updated it with the Pro version just so recently. As other reviews have mentioned, there's no clicking (I'm sure a lot of people got scared away by it, especially Zero Fidelity's video which highlighted it). Sound quality is great. I also have a Rotel A12MKII that's also paired with KEF Q150s. I honestly kinda like that set up slightly more, but can't tell if it's b/c of the better Rotel amp, KEF speaker quality (compared to polk r500s+aiyima), or if it's b/c I have to keep the Polks to low volumes (due to thin walls in my condo complex, whereas I can boom the KEFs as loud as I want). I'm a gamer who also likes to listen to music in the background, so this satisfies my basic demands, especially with a DAC with USB. Awesome. Interesting to note: if you buy from Aiyima directly on their website, you can get a significant discount ($30-$50), especially if you don't buy it with a power supply (many of us will likely have power blocks/cords that can already plug into the Aiyima). Personally I would rather NOT than take the risk, and would MUCH rather just do it via Amazon Prime b/c I can always return it within a month if I have issues. I think Aiyima has some pretty strict return conditions (like you can't have opened it). It would be a nightmare buying from them, realizing there's something you don't like, but you can't return (and maybe only replace). That's the risk you take of going with a random Chinese company: customer service and returns can maybe be tricky, but in terms of the product's quality and its value, it's absolutely phenomenal. One gripe with the T9 Pro is that there's no sub-out. It's fine b/c I don't need a sub due to my condo's thin walls. With the Aiyima's bluetooth mode, I notice there's a subtle static clicking noise out of my right Polk speaker (I was initially afraid it was a speaker problem, but this static is not there while using the USB). It's mostly noticeable when I put my ear next to the speaker, but still a sub-par result. Not sure if it's a ubiquitous thing or just something with my amp. Random, but the tubes can definitely get hot. I guess that's normal with tube amps. The remote is nice, and has tone controls for treble and bass. Other things at this price range include the Loxjie A30, which has a sub-out. I think those are reasonable alternatives. I was more excited with T9 Pro b/c of much Randy on cheapaudioman liked the original (even though Randy also had a nice video on the Loxjie), and the fact that the Pro was a new update, and I wanted the model that was the newest. The main thing to watch will be longetivity. I'm taking a risk like many of us are, but am optimistic that it will last me years to come, hopefully (otherwise I'll come update this review). Even with my aforementioned flaw with the bluetooth static, I'm still overall satisfied, and won't return it unless something major comes up. Remember, if you find a flaw you don't like, you can always return it with Amazon Prime.

What a cool little amp, with so many built in connection options. This being my first foray into Class D amps, albeit with a tube preamp stage, I don't have much to compare it to, sound wise. The closest thing I have is an older Technics Class H A/V receiver that I'd used for many years, and really enjoyed the sonically balanced, neutral sound. This Ayima sounds really good, but I could sense its limitations not long into the listening and testing process. The frequency response, on my system, came across as balanced but with just a tad bit of harshness in the upper frequencies. I didn't crank the volume excessively high, but I didn't want to given what I was hearing at moderately high volumes. The speakers connected were Q Acoustics 2050i towers, a rather neutral speaker with balanced, non-fatiguing highs, smooth midrange and prominent, but even handed, bass. As good as it is, the Ayima didn't quite sound as good as my trusty old Technics, or certainly not as good as my Class AB Cambridge Audio receiver. Because of this, I didn't keep the cute little amp. But had I not already had these other options on hand, I probably would've kept it and enjoyed it for what it was. I just had to see what the Class D hype was all about for just $150. I'd be interested to try other Class D options out there, perhaps with a slightly higher price tag, to give that type of amp a better audition with slightly better electronics.

When I got this AIYIMA T9 PRO 200W Bluetooth Amplifier, and saw how small it is, I thought, "No Way." However, "way". I am using it to drive Fluance Reference High Performance 2-Way Bookshelf and Surround Sound Speakers, and this seems to be an excellent match. The system has to be loud enough for me to hear the music when I practice jazz drums. I have been playing for many years, and, like many jazz drummers, I pride myself on not having to play loud. Nevertheless, the system has to be pretty darn loud. It seems that the amp delivers enough power even when the input is not excessively high. If i set my music playing software so that the amp's vu meter gets into the red a lot, The system delivers more than enough decibels for me to practice, and without much distortion. No need to drive the vu into the red for ordinary listening, and then the music sounds great with no noticeable distortion. I use the USB digital output to play everything through my computer: music files, cd player, and even my old ipod classic. Connecting the USB to my laptop running Linux Mint 21.2 was just plug and play; no need to install any drivers. Bluetooth from my phone works flawlessly. The controls on the AIYIMA T9 PRO 200W Bluetooth Amplifier HiFi Digital Class D Amp are easy to use and attractive. The remote, although flimsy as most remotes are, works fine and is a convenient addition. I have been building hifi systems since the sixties, and I fine it remarkable that this little amp performs so well. When I listen to orchestral pieces like Bartok's "Concerto for Orchestra", I like to hear good instrument separation. I think that this class D amp with vacuum tubes does that better than my good Sony AVR TV room driving vintage Bang and Olufsen front speakers. (Polk Surround) speakers. This difference in sound may be just a matter of taste. Of course the relatively small woofers don't provide quite enough deep bass, so I guess my next purchase will be a small powered subwoofer that will be fed by the AIYIMA T9 PRO line output (called "aux" on my unit). This is my second AIYIMA T9 PRO. The first T9 pro had a defective power supply of a slightly different type then the replacement. Amazon immediately exchanged that AIYIMA T9 PRO for an entirely new amp which arrived the next day. I am extremely pleased with this little baby, and its happy marriage with my new Fluance Reference High Performance 2-Way Bookshelf and Surround Sound Speakers for 2-Channel Stereo Listening.

I was a previous T9 owner and paired it with a set of KEF Q150 bookshelf speakers. I did some research and thought the T9 was the best all-in-one amplifier for the money. I used the amplifier to power my bookshelf speakers for my computer via USB and TV via optical. I am no audiophile (this was my first amp/bookshelf speaker setup) but it definitely provided clearer/cleaner sound then my klipsch pro media speakers. I did see and read the reviews about the "clicking" and thought it would not bother me. But after using it for month or so it would actually really bother me. Not only did it click all the time when switching between sources, but it would turn off/go in standby mode if not used for a little bit then click on again when sound came back. Very annoying. Then I was browsing amazon one day and noticed they released the T9 pro and looked at a couple reviews and they said the clicking was gone. Decided to try it out and I am so glad I did. THE CLICKING IS GONE!!! Not only is the clicking gone but the amplifier itself is more aesthetically pleasing. The tubes are shorter and slightly wider allowing it to fit better on my desk. I also like that there is now a digital screen that shows you the volume levels as opposed to the T9 when it was just a never ending, spinning knob. The digital screen provides a cleaner look, removes all the excess text on the amplifier and will also tell you what source you are connected to. As stated, I am no audiophile so I cannot tell much difference between the sound quality of the T9 and T9 Pro, but for the reasons listed above I believe it is well worth the $40 upgrade and I would highly recommend it if this is your first amplifier. It provides all the connections/inputs you would need. Is small and compact, but provides quality power and sound.

I've had this awhile now so can actually give review with some experience behind it. The good...well it's still working and I've had many different speaker combo out to powered sound bars out to pa speakers, in walls ...pretty much everything and it still sounds good. The overall power I feel is exaggerating a bit but it'll drive couple 50 w bookshelf's perfectly. Now the bad...I tell you if you have anywhere near to large hands or fingers there's going to be a big struggle tryna twist these cheap too close together terminals on back of this, then when u think finally got them tight and right...NOPE because they loosen with the slightest bump and the Holes wire goes through are sideways in some so it's just frustrating mess luckily it will accept banana plugs so save yourself the frustration..... Another thing and this is the biggest problem for me is the Bluetooth is finicky as I've ever come across in a device. Mind of it's own, if it wants to be nice for a session it'll show, but sometimes really like to mess with you and play the now you see me now you don't or it shows up but soon as you click get error message basically saying kick rocks I don't want to work at this moment. It's just crazy, if your buying mainly for Bluetooth listening I can not recommend this amp whatsoever. Wired optical , RCA, coaxial it's a good little budget option that exceeds the price point for sound imo. So there ya go, ...this Bluetooth man don't say I didn't warn you, it's a mess with every Device I've had and have.

As an owner and fan of the Aiyima A07, I was interested in checking out the Aiyima T9 PRO. Suffice to say, I'm very pleased with this amp so far. Overall, It outputs great sound while also taking up a relatively small footprint for my small desk. It also has a ton of really nice extra features, and to top it all off, it looks really, really cool. To start off with, the sound: I can say that out of the box it sounds wonderful. I use this amp with a pretty inexpensive, non-demanding pair of speakers (Micca MB42X) and this amp is more than enough for them. I find the T9 PRO is similarly clean to the A07, with no huge changes in sound signature. The T9 PRO might be a bit warmer, but I'd have to do some actual testing to tell. Personally, I prefer the clean sound, though someone who's looking to buy a pure tube amp might feel differently. I can tell you that though the T9 PRO might not have the signature high-end tube amp sound, it still sounds full and packs plenty of power. One neat feature I quite like is the built in bass/treble adjust. I often find equalizer adjustments through software inconsistent or lacking, so it's very helpful to have a very simple easy adjustment on the amp instead. It's something I missed when I switched from my cheap $30 amp to the A07 (though the A07 is certainly superior to that one in all other respects). As someone who finds my Miccas a bit boring at times, this option is a super nice convenience to add some occasional color and excitement. I tested the amp with some tracks like Polyphia's "Playing God", and with a slight bump to bass and treble, the song really comes alive -- the added emphasis on the low end makes the track extra satisfying while also not covering up the beautiful guitar parts. I also tested some other songs in the electronic genre like Madeon's "The Prince" or various songs by Weval, and with a controlled but sizable bump to the bass it sounds downright thrilling while avoiding being too blurred or muddy. Another track I demo'd was Dayglow's "Close To You" -- with some minor adjustments, the drums especially become particularly tight and punchy. The T9 PRO certainly has some other cool features as well. It has a wealth of possible audio inputs which is extremely convenient. It has options for RCA, Coax, optical, and even USB and Bluetooth. The USB option alone is super convenient if you want to quickly plug the amp into a computer, and it works plug and play without any driver installation or extra software needed. I also tested Bluetooth (with my iPhone 12), which is very easy to set up and works pretty well with no connection issues or anything of that sort. I personally run the T9 PRO through Aux/RCA, through my Schiit Magni Heresy which serves as a preamp, which is plugged into my Focusrite Solo audio interface. Works flawlessly. Aesthetically, it has the VU Meter and a dotted meter on the segment display, which both respond to your music. It's a nice added touch, and the glow from both along with the tubes makes the amp look really cool, in my opinion. The knob is also particularly nice quality; it has satisfying steps instead of being completely continuous. You can click in once to mute, or twice to adjust the bass and treble. The amp also comes with a remote which is a nice touch. I unfortunately haven't tested it since I don't have AAA batteries, but it's nice they included it. One question one might have is how it compares to the old T9, non PRO. I must confess I have no personal experience with the T9, but I have seen reviews and feedback on it. It seems like a relatively well-liked device overall, save for an issue where there's an audible clicking after input ends, which seems to be a large pain point for many. I can happily say no such issue exists in the T9 PRO. That issue sounds quite frustrating to me so I'm happy Aiyima fixed it on this one. Another question one might have is how this one compares to the Aiyima A07. I find both to be entirely capable devices, but it depends on what you're interested in. The A07 is a powerful, no-frills amp at a great price, so if all you want is something simple I can still happily recommend the A07. However, the T9 PRO features some nice added bonus features like Bluetooth, bass/treble adjust, and looking extra cool while being more compact overall. I find its compactness to be particularly nice as my desk is quite small, so I would find this suitable for desktop PC usage in a private office or a small dorm. If you happen to own an A07 already, I believe you can connect them together, though I haven't tried that. I do have two very minor gripes: -The VU meter and green dotted meter that responds to your music seems a bit insensitive. At first I wasn't sure if it was working properly, but they certainly do -- you just have to crank it up. Unfortunately at those volume levels I would probably piss off all my neighbors so at my normal listening levels they don't move a ton. This might not be Aiyima's problem though, since I do wonder if I used more high-quality, demanding speakers if it would then be more responsive at reasonable volumes. I also might be misunderstanding how they work, since it seems they respond to your overall volume and not just your input signal volume or volume on the amp itself. I'm unfamiliar with VU meters so I do wonder if this is just how VU meters work in general. -the amp and tubes can get a bit hot after awhile. Nothing too concerning, but if you happen to have very small children I would be cautious. For most people though, it shouldn't be a problem. I assume by nature of being a tube amp, this is fairly normal behavior. Overall, the T9 PRO is a powerful great sounding amp in a compact package with some nice extra features. If you're looking for something that's surprisingly powerful while also looking awesome, and/or if you were interested in the T9, I can safely recommend the T9 PRO.
