Fosi Audio ZA3 Class D HiFi Stereo Amplifier with XLR/RCA Inputs

These are great! It seems as though in the audiophile community even a 3k amp is considered ’budget’ which is ridiculous, I don’t claim to be one myself, I just want to enjoy a higher fidelity of sound, and this product does a great job, I have it paired with the Wiim Ultra, as my desk audio setup(overkill for sure) it is Near field excellence! I can’t wait to try out the mono configuration, with my main speakers.

I'm enjoying these FOSI Audio amps so far, using them on Polk Elite Series speakers. No distortion clean loud audio.

Excellent product and also first class service from Fosi. Highly recommended.

I'm powering pretty inefficient speakers using 2 of these in mono (THANK YOU to another reviewer who clued me in to just using the red inputs when doing this).

Ok. A pair of these are going to sit beside my integrated tube set up. I have to be careful with my tube set up because of speaker impedance differences. These can handle whatever you throw on them and they do it with no sweat.I ordered a second one for the mono aspect but it was wonky from the get go. I have a replacement coming. Hopefully no problems with the second one. The potentiometer volume control had an issue. The right channel would start way before the left at low volumes and the output was not even close to the first ZA3 I purchased. I hope this will rectify the problem.The first one I purchased is just darn good.Received the second one. No problems so far. Highly recommend
