Comments please on: NAD M23 vs c298 vs. other newer Class D


I'm interested in comments about the new-ish NAD M23 amp. It gets rave reviews on the Absolute Sound channel, by Doug Schneider and by the review at Sound Stage, and by others. Reviews describe not only an even response across frequencies, but layering of the soundstage (left-right and front-back) as well as excellent measurements. Some describe the sound as somewhat tube like in the mids and upper range, others as neutral, but all agree it does not have the harshness which typically characterized reports about earlier amps with this design.

I am not giving up my Pass XA 25, nor my QS Mono 60 tube amps. Or my ST-35 Dynaco. What I'm interested in is a another amp in the stable that can play nicely among different speakers (not all are as sensitive as my main 97db ones), and that might bring that snappy dynamic speed to the sound but without making me cringe from the highs.

If you have some opinion of this Eigentakt design, especially in comparisons to Atma-sphere's Class D or other amps with similar technologies inside, please comment. (PS Audio, Bel Canto, et al.)

If you have some opinion of the NAD M23 vs. the cheaper-but-still-Eigentakt NAD c298, I'm interested in that, too.

I'm NOT interested in super pricey amps. Say, above $8k

@atmasphere I am in Colorado, and there are no dealers here. I might go that route but between shipping and putting down full cost, I might not want to do that. It will be simpler if I can find a local Denver person who owns these and maybe we can have a listening session. I don't know if I'll be able to find them, but I'll try.

No slight intended towards NAD as I've never seen or heard one of their Class D amps.  Just a simple statement of fact.

"@hilde45 if I can find a local Denver person who owns these and maybe we can have a listening session". 

And, then of course the most ideal situation would be to bring them to your house, with your source, your preamp(s), with your speakers, in your preferred listening room.   

I pretty much came to a conclusion a few years back that listening to familiar components at shows and other people's houses will result in too many other uncontrolled variables. It can actually create more confusion than benefit imo.

@decooney I’m at the point where if I cannot listen to a more expensive piece of gear in my room (which is extensively treated, balanced, measured and assessed with my own ears), then I’m not going to buy it. I have heard any number of pieces of gear in really crappy stores and also in other people’s homes where I thought, "I have no idea what this would sound like in my space or in a decently treated space."

It’s a weird kind of situation, in the sense that it’s like pseudo-science. People pretend to be listening to the gear, making observations and judgments, but there’s so much in play that is not acknowledged that the comments made are more like Kabuki theater than actual science. Audio store owners love to engage us with patter about this or that aspect of the sound – and I know this is their job – but what bugs me is that it is pretend empiricism, not actual empiricism.

Conversations on fora like Audiogon go on and on about the sound of gear, but the room is half the equation, so a lot of these conversations are basically people just expressing what they hear or like. Is there anything "wrong" with that? Well, no, unless it’s being stated as if it were fact. And that’s what a lot of people do – they express it as if it were fact to add emphasis. But without some responsible reportage about the room's acoustics, this is just rhetoric. For a cheap piece of gear, sure, I’ll try it and see. But if we’re talking thousands of dollars, well, I’m not interested in gambling. There needs to be a fuller accounting of all the key acoustic factors in play, including the room.

Where do we listen to our systems, right?

LIVING ROOM GUY HERE:

I’m nowhere near where members are here with dedicated and treated rooms. By choice I keep my main system where we are the majority of the time, and there is dedicated listening time and what I call "walk-around-listening time" too while we are doing other things and yet letting the system play for 4-8 hour stretches on weekends, etc. Like it was growing up in the 70s for me, part of the enjoyment.

All of my listening and testing goes on in my main family room, with various items to the sides, furniture we sit in out front, as any normal family room has.  

My final main speakers were designed, built, tested, and tweaked using this family room as my final test bed. Unless I go and listen to gear in a room similar to mine and with my sources and such, its really a nice thing to go look at  to get a "general idea", but I KNOW 100% I won’t know what its actually going to sound like until I get it home, broken in, and warmed up over a few weeks time - at least. For sure.
