High end Class D amps?

@klh007 The 10K gives it away--it's the LKV Veros, already reviewed vry positively by Herb R.

Technics GaNFET: Dry, sterile, boring. Burned it in for over a month. The cheap integrated unit.

I don’t claim to know all the Technics GaNFET units, but I am not aware of a "cheap" integrated unit and considering you are using relatively "cheap" Odyssey Stratos, I am not sure what you consider cheap. Even a new Cherry is a fair amount more money than a standard configuration Stratos. Do you mean the G700 which I don’t think uses GaN. SU-G30? .... that is $4,000.

I don’t have the engineering chops to add much to this discussion, and neither do I have a dog in this. It would seem to me that much of this difference of opinion might be about the theoretical possibilities vs.actual consumer available units that have actually been measured to offer those theoretical possibilities. My limited experience with Class D amps suggest quite a bit of difference between competing units, and though to this point none have convinced me to switch from standard ss amplification, I am truly excited by the potential of Class D (or whatever variation therein) amplification.

It was the SU-G30. I bought one used for $2500 if I recall. I meant cheap in relation to the other Technics GaNFETs. The Stratos was picked up as a "filler" amp until I get get something better like a Mark Levinson, Esoteric, etc., but they worked so well with the ProAcs that I haven't been in a terrible rush to move on.

I think I stated earlier in this thread that I used to own a pair of Nord Hypex NC500 monoblocks. There was a lot to like about them, and I think they delivered compelling performance for the price, but were not as engaging as I was looking for in the system I had at the time. But they convinced me that class D holds a lot of promise. 

In the past year, I've had a lot of fun building DIY electronics (two pairs of monoblock amps and a preamp so far), so I've decided to try building a class D amp as my next project. I like monoblock amps for a number of reasons, so this project will be another pair of amps. I'm using the Purifi modules, and using a high-current linear power supply (1500VA) for each amp, and leaving room in the chassis to experiment with different input buffers. 

This probably wouldn't be cost effective for a commercial product, but that's what's fun about DIY. 

I'm going to use the Neurochrome buffer to start, but I've already started designing a buffer with a single-ended class A output that I'll try for round two. I've got a few other ideas in the works for other input buffers as well, so I can hear for myself how they affect the sound. 

I hope to be playing music with the Neurochrome buffer by the end of the month.
