Unless you have heard the very latest and best class D amps then you have only heard history.
The brand new Merrill amps have way more musical and detailed sound than the previous Hypex Ncore based amps. You can read some comments on their site and more info will be here shortly.
The brand new Nuprime monos are suppose to be killer.
My about to be released $1000 and $1900 tweaked ICEege amps are seriously great sounding.
My own reference amp for the past 5 years is a class A amp designed by myself. It is dual mono and super, super pure and tweak in all ways....only two fets and two resistors in series with the signal per phase. Well, the ICEedge prototype is overall better.....better in most every way.....and I have three more things to try on the proto amp. I don’t want to go back to my class A amp.
Here is something to ponder......All connectors suck....and I mean big time! I have hardwired my amps to my x-over and speaker drivers for years but only in the last year did I remove the connectors on my interconnects. I had no idea how bad they were. I will never have any connectors (except AC) in my system again. If you have connectors on a warm or colored system then the system still might sound musical. However, having connectors on a pure "straight wire" system will bring agony to the listener. Connectors sound like bad class d or digital....really....grainy, compressed, Aharmonic, rolled off......just bad. My new amps will have my binding post bypass system where the binding post is used only as a clamp, that clamps your speaker wires (hopefully without connectors) directly to the wires coming out of the amp. I will also have optional hardwired interconnects on my amps and also have optional hardwired short pigtails hanging outside the amp that you can solder your own wires to. All these things have never been offered on any amp before (except for my previous amps that had my binding post bypass system).
This is just the beginning.
I predict that in 2-3 years Class D will be so close to pure straight wire that all other amps will then be history except for those addicted to coloration. Class D will also become even more efficient and smaller and cheaper so we will all win on all counts. The class D revolution has started.
