The amp feels over engineered and heavy duty. It has a high damping factor and low distortion.
I chose it because it is an AB type AMP, which is supposed to have lower distortion over the H class amps.
Running 4 15 inch JBL speakers off it and it has good punch.
This is an excellent amp for home hi fi as well as pro sound - just remember it has a fan that you will be able to hear at low volumes if you are in the same room. For such usage, you should put the amp in a cabinet to muffle the sound. This type of amp can get hot under heavy load so it needs the fan, but unless you are doing pro shows it is unlikely it will even get a bit warm.
Note that if you do use it for home audio, the input connectors are XLR plugs, so if you have RCA or mini jack outputs, you will need a cable that converts those to XLR - which Amazon sells.
Also, do not forget to buy a DBX equalizer, ( DBX is made by Harman, which also makes JBL and Crown ). Makes all the difference.
the only issue I have had over the years is condensation in the volume controls (potentiometers), making a cracking or distortion when raising or lowering the volume. Which always affects where I tune the left volume level with the right volume level. I use electrical contact cleaner.
With the amp in the off or on position, remove the nobs by pulling outwards then spray inside while turning each volume control up and down rapidly several times. That should clear the cracking noise when raising and lowering the volume. My QSC RMX850 is not the most powerful in my rack, but my #1 Amp in the Rack
