Bluetooth 5.0 Stereo Audio 2 Channel Power Amplifier Receiver, Mini Hi-Fi Class D Integrated Amp 2.0 CH for Passive Speakers, 100W x 2 with Bass and Treble Control (DA1002C)

I love this thing. Great little stereo amp for my desk. It's beautiful and woks like a dream. Powers a 4.5 inch sub pretty well too. Solid purchase for a desk or very small media setup.

More reviews on practically identical PROZOR.Pros (for me) Small size for a shallow shelving. Right priced, usd$59. Simple yet with a good complement of inputs. Cool Running. Full function remote. BT pairing doesn’t produce any annoying sound nor does it send an AUTO PLAY. Standard SMA WIFI connector allows using better looking remote antenna.Cons (for me): Pin holes making LED indicators visible only dead center. Same small hole causing the need to aim the remote directly to it to function. IR responses twice if one holds the buttons too long. Better IR systems know to ignore - -repeat sends. Not keen about the red knobs, am planning to replace them with some nice gold knobs. No volume change indicator. I would have preferred a built-in power supply like my old Teac Ai101DA. Big spark as power plug connects. Power/on-off by pulling the AC cord instead. No Subwoofer out but that shouldn’t deter any sub with High Level Inputs. No headphones jack.Sonic Performance: Am using this to drive a pair of 3” woofers in the near-field bedroom at night so not pushing hard at all, I did not test this with large speakers. Don’t take the 100w x 2 literally, is a very small amp, it can’t do magic.Long Term durability and performance: Unknown, I have only owned this for 6 weeks.Other: Surprisingly a full function (for the $) USB port, but I don’t use it so sorry no in depth review here. It remembers the last input for me in contrast to some other reviews. Can play at low volume soft levels in contrast to some other reviews. Tone controls seem to work normally in contrast to some other reviews. For slightly better appointed units, check out RockVilleAudio.com (u better love blue).

Was a little aprehensive to purchase this amp, as it's a brand I'm not familiar with, and not many reviews. I like that it has all the inputs I would be likely to use, the Bluetooth pairs easily and has good range, and the output power is surprising for it's size. I have it hooked up to a pair of vintage Dynaco A35 speakers from the mid-70's, and the sound is very nice. I have been playing CD's using a DVD player via the coaxial digital audio input, and Bluetooth from my phone or laptop. Very impressive little amp for the price.

Wish you could control more volume, it seems the dial turns more freely to up but it doesn’t equalize to the volume of more sound . Overall it did work.

TRANSPARENT FULL BODIED SOUND VERY MUSICAL...

Ok this is the first review by an actual buyer, not a Vine customer. First brush, very cool mini amp. The red knobs grabbed my attention and I figured why not for $65 for a bedroom system. Paired with some NHT speakers and an Monoprice sub and for under $200 a great little system. The mid-range adjustment actually works and adds to the contouring of the sound. Not sure about longevity, but I'll update if necessary.

Perfeftly loud for Bose outdoor speakers that Im using as desktop speakers mounted under my desk with optical cable from my computer.

You can press in the main volume knob clicks into switch inputs, and is otherwise just an encoder wheel (no stops, detented movement). The RCA LED blinks to indicate minimum volume reached, and OPT/COA blinks to indicate max volume.The equalizer knobs have fine detents, but only span a fixed range. Would have preferred rubber knobs, or something with some decent grip as they take a bit too much force to turn. These are real physical potentiometer knobs, they directly control the equalization via some OpAmps.The remote just exposes most of the same features in a little bit easier to access interface. You can't control the equalizer from it though. Play/pause button doesn't just control playback, it will actually mute the output if you're using the stereo/spdif inputs.It powered on immediately when I attached the AC adapter which caused a spark. Probably should connect the adapter to mains last.Only seems to support ADC bluetooth codec.== Build ==Construction looks pretty good. The case is a very solid extrusion with a thick front plate. Rear connectors and front controls are secured to the panels. Large internal components such as inductors, and the main capacitor are secured with glue. The only thing I don't like is how the front LEDs are attached, just long leads bent over so that they line up with cavities on the face plate. It works, but it's a bit annoying to install the face plate, and the LEDs just look tacky.== Components ==The main amplifier is TPA3221 as described. The DAC is RuiMeng MS8412. There is a HEF4053BT (Triple analog switch) which probably does the three input switching (BT/USB, Analog, Digital). The bluetooth and control chipset appears to be JL BP0G635-26A4. A pair of TI N5532 Dual OpAmps are controlled by the front equalizer pots.The main input cap is 35V rated which seems fine for the 24V power supply. The rest of the electrolytic caps for the amp side are Beryl RC(M) 16V 470uF. The recommendation in the TPA3221 datasheet is that the PVDD supply caps be 50V low ESR caps, but there's nothing like that in the device. I think I would avoid using a 30V supply with this, and high power outputs might also be problematic.
