Need Advice & Need It Fast

Class D from the likes of Hypex and ICE are magnitudes better than those of yesterday (PS Audio uses ICE and ATI uses Hypex). 
 
What is your budget and listening distance? The Nova is a solid performer.

There is a class D forum here which will be well worth your while to investigate. I’ve been using class D for over a decade, but have owned Rowland, Kinergetics, Parasound, Joule, Rogue, etc

Class Ds included several; PS Audio, W4S, Emerald Physics 100.2SE and currently Audio Alchemy stereo amp & dac/pre. The AA amp blows away the EPs, which I found thin in the mids. I am getting a full set of PS Audio; 700s and matching dac pre just to compare to my much loved AA amp//dac, as I have a big room and might benefit from more watts.

Of late, I discovered just how important cables and power cords are with class D. Now, I always used quality cables (Nordost, DHLab Revelations, pure silver from Clear Day Cables, PS Audio.., but class D is so dead quiet, with jet black backgrounds it is extremely revealing of cables and power cords! It has shown me that just because cables are expensive does not mean they are worth it. In my system, recently switching to WireWorld Eclipse series 7 and 8 has been a jaw dropping revelation

If your system has a lot of mains leakage (harmonics of 60Hz for Americans), then the WireWorld does perform better than generic cables (mostly due to the wiring technique and shielding, nothing magical). However, if your system has no electrical issues, then generic should perform just as well.

Have you tried the NAD mini-integrateds??
