New Class D amplifiers


Hello. I'm very interested in getting your opinion on the newer Class D amplifiers.  There has been a couple of very positive reviews (by Guttenberg) of the Bel Canto C6i and NAD M23.  These, and perhaps some others are offering new technology that significantly lower the class D noise level and other drawbacks.    

I currently use a Class A amp, Pass Labs INT-25 (with Dynaudio Heritage Special speakers) which has a wonderful sound. But I am transitioning to another location, and due to using Roon primarily I find that this system stays on most of the day.  Due to heat and power usage of Class A amplifiers, I'm interested in translating to Class D if I find something comparable.

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.

Sorry to hear you did not get the assistance you need with your Voyager. BTW, I have one and love it!

Do you know Ric Schultz from Tweak Audio? He does mods, including the Voyager You might contact him about his upgrade. I have his EVS 1200, a ground up design based on dual AS1200 Ice modules. I have owned many many amps over the decades, tube (including servo and OTLs), SS (class A, AB, D) his EVS 1200 is one of the very best amps Ive ever had

My V chassis is all metal. My system is all XLRs, so never tried the RCAs. Maybe shoot Ric a couple of photos pointing out the situation

Good Luck

I can't try anything as I had an accident when I was moving it with the lid off, but resting sideways on top (plugged in f course... the top fell in and it crashed into one module  creating BIG sparks. Fortunately, I was able to drop the EVS1200 in its place until I get it fixed. Im not in any hurry as the EVS sounds amazing

Thanks for the 411 on Daniel Hertz, aka Mark Levinson
