I had a younger brother of this amp (DA2120A) and loved it! But I use Micca RB42 and they are pretty ineffective. In fact, even this combination is more than sufficient for desktop use. You will not be disappointed with this combination! I needed a little more power so I switched to a Fosi 120W amp! This amp is the big brother of the DA2120A with a slightly larger case and significantly more power. This is a fantastic device that easily doubles its value. Haven't tried bluetooth input since running USB from my PC. If you have more efficient speakers, the little brother with 50 watts per channel is enough. If you have anything under 87dB I would recommend this guy. I have very high end audio equipment (about $10k system) and consider myself an audiophile amateur. I am currently fully occupied in an RV so space is at a premium. Featuring a Micca RB42 and a flat 10" Dayton subwoofer, this Fosi DAC/amplifier is an ultra compact yet incredible sounding 2.1 system for music or movies. OK. I can't comment on the image or other more subjective qualities of the amp as I'm in a sub-optimal area to rate this. Distortion is low, it looks great on the table and it's packed with options. I love this amp! Even the remote control is great. It's just plastic, but it does exactly what I need it to do. I returned the first DA2020C as defective because I couldn't get 192kHz sound from my USB PC. The second was the same. I use both Windows 10 and Linux and both had the issue. I finally played around with my settings enough and it worked. I'm wondering if this amp's little brother worked initially, it caused some sort of driver confusion when plugged in. in. I'm not sure. But I'm sure the seller was very helpful and gave clear and helpful advice on possible solutions to the problem. Great support makes this amp an even easier choice!
