Mini Small Stereo Audio preamplifier, Headphone Amplifier, Gain 20dB Phono Turntable Phonograph preamp, Dual op amp NE5532 with RCA 3.5mm Input to RCA 3.5mm Output

At first I thought this would just be another preamp I would test and return but it's actually pretty good. The line out of my iPad didn't quite have enough volume and this did the trick without distortion or coloring the sound.

It does the he job I need it to do. My record player just needed a small boost to the line level to match the other inputs to my amp and it does it cleanly.

This is exactly what I needed to boost the volume of my Optical Digita to Analog Audio Converter.

Not as loud as I hoped coming off my turn-table into my (already powered) speakers, but gets the job done

I had my Mac connected directly to my Fosi V3 and it just wasn't loud enough, dammit. So I bought this tiny doo dad and holy crap, not only is it much louder but it's just as clear as it's supposed to be. I haven't tried it with a turntable yet since my amplifier has a pre-amp built in, but if I do I will add to this review.

After testing new product: AtNeDcVhcan 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 changingspeed of a playing track. It's not of course super expensive device,that exaggerating sound, and to my opinion is focusing on midrangegiving pretty full sound range. Can produce trembles well, trianglesand cymbals were pretty good, not as airy and copper like as withgood tubes, but still very-very good. Bass and mid-bass were withoutany 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 systemto 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 enoughwithout 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 smalleither on a side or on a front panel:there is no need-to-know exact model and it is bothering too muchand 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.

Worked perfectly to boost up audio signal from a Media Player

P.o.s. Burned out as soon as I turned it on
