I had followed these class D discussions for a while and wanted badly to try them in my system! I had one of the best class A power amp(Pass Labs) and really like it but size, weight and heat were factors that pushed me for class D! I got Hypex Ncore 500 and for the first time can hear the differences! Ncore is more accurate to PL (might be because I bought PL as 2nd hand and it was old) Ncore has better control on bass and easy to drive any speaker but it is not as musical as PL to my ears specially on low volume ! Long story short, a good class D is amazing for newbies and ppl that don't consider themselves as an audiophile!
