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

how were you able to make a Class D module that competes with companies like NAD, Purifi, et al.? It seems like the kind of thing that teams of engineers and iterations of product development would require and you did it alone? That's astounding.

Second, will there be another iteration of your class D amps? The ones you have now are the first generation, while other amps in this class seem to have gone through a number of "evolutions." Is there a new Atmasphere Class D amp version in the works?

@hilde45 A lot of people think we're a tube equipment manufacturer. We are, but really we are an engineering firm. As to how we did it, it took time, patience and an understanding of math. There's not a new version in the works. The amp has met our expectations out of the gate. 

@atmasphere Thanks for your reply. I've heard your amps once, here in Denver. They were played with large Tekton speakers in a room that was too small. The brightness and shrillness was unbearable, but I'm sure it was the fault of the speakers and room. If I am able to try them out for myself, in my own system, I'm most curious to give them another listen. I admire your work, your career.

@hilde45 "...speakers in a room that was too small. The brightness and shrillness was unbearable, but I’m sure it was the fault of the speakers and room.".

"Unbearable" you say. I experienced this once in an audio show room with a very well known high quality amplifier manufacturer paired with a well known speaker manufacturer, and music tracks being played by someone who does this regularly. 

The components were great. The room setup and result was absolutely horrible.  The worst sound out of 87 different rooms.  I’ll never forget it. Embarrasing, and I felt bad for the people running the room, as visitors came through, and you could see the expressions on their faces as the room emptied back out, quickly. 

As we well know @hilde45 until we get any of these components into our own rooms, running with our sources, our cables, our setups, its a crapshoot guess at best if any of us take other’s feedback too seriously. I remind myself of this regularly now when I see posts by folks about gear that sounds great in my room and horrible in their rooms and setups.  Lots of other variables as we know.  :)  

@hilde45. I have the Class D Mono blocks from Atmasphere and they are not bright or shrill in my system. I would assume that was an effect from the room. Ralph is super easy to work with and he has a very long home evaluation period.

Good Luck..

Rooms at shows are always tricky. The best time to hear equipment at a show is usually the last day, when the people in the rooms have sorted out how to make things work. I've had so many shows where the first day sucked. 

I've never been able to get a room at a show to sound as good as at home.

IMO the best thing at shows is to allow you to meet people. And some rooms can sound quite good, but you must always look at that as a side benefit :)
