Review: AtNeDcVh really small, but very good Stereo Audio preamp - After testing new product: AtNeDcVh can confirm that it is built with very good quality. No hum, no noise, all connections: inputs and outputs worked as expected. Lots of functions, several options for inputs and outputs - well thought, well designed. Simple. Volume knob is small, useful, do not throwing to eyes, yet can be used without a problem. Volume even on 10 o'clock is giving adequate volume, again without any hum, noise and issues. Device is not slowing down pace of tracks, seems not changing speed of a playing track. It's not of course super expensive device, that exaggerating sound, and to my opinion is focusing on midrange giving pretty full sound range. Can produce trembles well, triangles and cymbals were pretty good, not as airy and copper like as with good tubes, but still very-very good. Bass and mid-bass were without any booming and presented all range very good. Black, silence was clear, good imaging and ending air was presentable. I tried it as a headphone amp, as preamp before and right after a turntable, in receiver in mid of tape monitor loop, boosting a tv and external speaker system to passive speakers with low sensitivity to a desirable level. Overall - very good and inexpensive product, which can be used on many occasions. On almost all situations volume at about 10-10:30 o'clock was good enough without changing much of the sound. To manufacturer I can advise a couple options: - Power supply cord is really-really short. I'd say too short to standard use. - Reduce the logo on top of the body by making it really small either on a side or on a front panel: there is no need-to-know exact model and it is bothering too much and aesthetically is not very good. - Hope, that designer team can play with other options, like: - adding tone controls (Bass, Tremble or even Mid); - along with tone controls adding an option to use 12ax7 tube. (or even replaceable tube inputs/holders to use various types of tubes, but there shall be better testing to make it without any hum and noise, making such option much better and reliable, then Bellari phono preamp as example.) I'd love to see those options, especially if price will be adequate. Again: AtNeDcVh Mini Small Stereo Audio preamplifier to me is very good and built well product.
Review: Cheap, reliable, and easy to use pre-amp delivered with specs as advertised. - This is a variable power, 20 dB max pre-amp probably with 47 k-ohm input impedance and able to easily drive an amplifier impedance of 47 k-ohm. At full power it delivers very close to 20 dB of gain. It worked immediately out of the box with easy and obvious connections. The blue power-on LED is unnecessarily bright but other than that it's perfect with no noticeable distortion. I use it after a blue tooth receiver paired with a television to drive a stereo power amplifier.

## Features

- It is applicable to power weak signals into line-level signals. The amplification multiples are 10 times (20dB). It can directly drive the headphone to work (the headphone output port can't be used with other output ports at the same time), the max headphone impedance supported is 16 ohm.
- Using the classic Dual OP AMP NE5532, high frequency electrolytic capacitor, noise reduction circuit design, no background noise, effective gain audio, improve sound quality.

## Questions & Answers

**Q: Are all the output jacks amplified output, or do the outputs on the back provide line-level audio and the phones output on the front is amplified?**
A: I would say yes, but that’s not what I’m using it for

**Q: Does this have riaa eq or is it a flat preamp?**
A: Unfortunately it’s a flat preamp.

**Q: Plugging it from headphone jack on tv to bigger speaker in my van and it sounds bad when i turn it up a little. Any ideas?**
A: It sounds like the output might be too high (amps) even though the sound isn’t that great. You could try to change the combination of settings until you find one that sounds better i.e. turn the tv volume down and the preamp output up or vice a versa until you get a combination that sounds better

**Q: What type of pin or plug fits into the ground hole?**
A: There are no dedicated ground 'holes'. ground is either the other ring of the female RCA connectors or the ground position of the stereo minijack (3.5mm).

### ⭐⭐⭐⭐⭐ Works Exactly As Advertised
*by R***. on January 4, 2026*

I bought this to boost the audio signal coming out of an old DVD player, before sending signal to a Bluetooth transmitter and finally to a Bluetooth speaker. Does that perfectly, with zero additional signal noise. A perfect and inexpensive solution for my needs.
