"D" amps, general discussion who's 1 and why?

Geph0007,

I have a NAD 7020 I use as a spare in my systems when needed.

Its a very gutsy little beast indeed, and it has served well in a reserve role when called on over the years, but the sound is quite rough around the edges compared to most newer and even a number of older amps that I have had opportunity to compare it to over the years.

geph0007 good write up,it is hard to pin down,whats not hard to pin down is that the brain and ears will surely tell you something is wrong,and they cant be fooled.

Class D amps, ones that are superbly designed, can approach reality given the right system gear. I can show you, Coffeey, how I can make my, "Amps," sound edgy, fuzzy, bright, and/or distorted just by inserting a regular CD player, off the shelf wires at any price, stock power cord, or a noisy and badly matched preamp.

Coffeey, as you well know, the Bel Canto EVo2, Gen 2 in question is approx 3 or 4 generations old. . . it does not even faintly represent what best of breed class D amps can deliver today. Have you considered getting a fresher perspective than the cherished solace of old bad memories?

Very interesting information with all the different thoughts and out comes.

Aprox. 2 years ago I bought and demoed numerous class "D" amps and/or which some refer to as switching amps.

What I found interesting when I read what Geph0007 had to say in general, putting aside the gear that was made reference to because that totally differs from what I listened to including owning.

What did come across was these specific amps ("D") are in one category referring to saying it's so clean, great bass, it's so smooth, etc. Then there is the other category which is "emotional where you want to jump up and start playing air guitar or you get choked up if the mood is right on certain songs."

I have to say from my experience I agree and that is what I was missing when I did my demoing but as we all know lots had happened since then (improvements)and I always keep an open mind so that is why I still have interest.

I have this year done some more evaluations comparing and here are a couple situations and what my thoughts were, these are my thoughts only!

System;

Jeff Rowland Continuum 500 integrated amplifier paired up with Neeper speakers, JM-LAB Alto Utopia Be speakers and Sonus Faber Amati Anniversario speakers. Cables used were Transparent and source AR REF7 cd red book, Esoteric with clock and DCS stac. Material all cd

I listened changing only the speakers and sources, same day and all gear well broken-in.

The JRDG was in the rack, on the floor was a Audio Research REF110 and HD220 both stereo pces and there was a REF3 pre also in the rack.

I spent some time listening to the different pcs. in different configurations with the JRDG first. I actually went with the intentions of buying the JRDG 500, the Rowland sounded really nice while I was evaluating and mentally going through the Audiophile check list, in my mind it was truly doing a spectacular job but that's it.

I played the same pces of music that I'm very familiar repeditively. I then switched over to the ARC amps and I discovered immediately what I was missing and it was exactly what Geph0007 said; which is the emotional aspect where you want to jump up and start playing air guitar or you get choked up if the mood is right on certain songs.

I just actually forgot all about the electronics and melted away being drawn into the music emotionally. It really reminds me of two years ago and how I felt also when I demoed "D" class amps for aprox. 8 months and then installed PASS X600.5 mono blocks.

So my latest exspearince, JRDG 312 stereo amp paired up with a ARC REF3 pre., Transparent cables and same sources again but with the new JM-LAB Scala speakers. First time I ever heard these speakers and the 312. Very nice experience indeed and much different than my past with the JRDG 500 and all "D" class. This set-up offered that emotion toe tapping experience that is very important to me that was lacking so far with all other "D" class amps that I have heard.

Still more auditioning to come as I now need to compare, ARC HD220 and REF 110 and Boulder with same speakers and electronics, should be interesting.
