New Class D amplifiers

Alo try Wyred 4 Sound stuff. They have everything and had the mono block mated to my CJ preamp and sounded amazing. Wish I knew what I had before I sold it. Light weight compared to the back breaker Audio Research amp I have. 

At present, I have a Luxman m-700u/c-700u combo and PS Audio M1200 mono/PS Audio BHK preamp combo in rotation. The PSA M1200 amps use IcePower modules with proprietary tubed input stage. These two amplifiers are a near dead heat in sound quality, just different strengths. There's no clear cut "winner." Like Erik Squire's previous post, I prefer the Luxman combo for the type of music I listen to but could easily imagine someone else making another choice. 

The implementation of custom input stages using the IcePower modules is apparently important. I also have an amp that just uses the stock unmodified AS1200 module with high end Furutech wiring and connectors and it doesn't hold a candle to the performance of the PS Audio amps. There is also a difference in older IcePower modules vs. modules used in Legacy and PS Audio M1200 amps. The older modules used in many amps are decade old tech. 

After a number of various switching amplifiers through the 2000's I found a pair of early Hypex NC400 kit amps to be noticeably preferable in the mid and upper frequencies. I use them for recording playback with monitor speakers. I still use tubes for listening.  

I haven't followed Mr. Putsyes later models but I have noticed a number of speaker manufactures are using them for their powered systems. Interesting designer.

A hidden gem to perhaps convert the close the class a heaters sonic gap.

I have both an LSA Voyager GaN 350 (dual mono) and EVS 1200 based on dual IcePower 1200 AS1 modules. I was using the EVS with Ali-Express Nordost Odin 2 speaker cables and Odin 2 XLRs, plus Odin 2 coax, and while exceptional, my system has terrific detail, but lacked a rich dollop of warmth. Since these cables are super inexpensive, I replaced the XLRs with Odin Gold, which helped, so I wanted to change out the coax too, but couldn't locate it, so instead, I bought Odin Gold speaker cables, for a mere $128/3m pair!!! These provide a much better sonic match (warmer rounder without sacrificing any details that the Odin 2 provides.

I appreciate all the suggestions and i'll be looking into each one!  I do favor  integrated options since I prefer not to get into a preamp as well. but the mono block options are very good.  i wish Atma Sphere had a class d integrated now which i think is being developed.
