## Customer Reviews

### ⭐⭐⭐⭐⭐ What a steal!!!
*by A***R on February 7, 2020*

This little (only physically) amplifier is Directly connected to a pair of high frequency compression, coaxial drivers above 1200hz. The amp itself has a very quiet background.I was shocked at how much better this amp sounds compared to a highly regarded class ab. The difference was night and day, the highs just seem right, spooky almost. I had to completely adjust (and flatten) my DSP processing. How’s the bass?? I don’t know, but the highs are superb.....
