It's time to move up in my system. I'd appreciate some amp recommendations, as I haven't heard too many amps, and have little knowledge of some of the nuances involved in making a decision. Field testing amps is also difficult where I live.

My system is Magnepan 3.7 speakers; (2) Vandersteen 2wq subwoofers; Mojo Audio Mac Mini feeding a PS Audio Directstream DAC, straight to amp. No preamp. (Transparent ICs, Shunyata Triton, Anaconda PCs, DH Labs and Silnote SCs.) The current amp is a very fast and very powerful Class-D switching amp with tons of headroom.

The system is noiseless, clean, precise, detailed, neutral. The soundstage is huge, holographic, and immersive. Live recordings are the bomb. Sometimes it seems a bit sharp or harsh, but that's often the recording or the room. Overall, soft and sensuous, it ain't, but I can hear every note and breath.

I've heard some denigrate a different switching amp -- "I can hear the switching." This from a tube guy. I'd prefer not to get into any Class-X wars.

A local dealer is suggesting I look at Bryston, a classic match for Maggies, I'm sure, but he also suggests that the Bryston can be somewhat two-dimensional. His solution is a Levinson 532H, which he holds as more three-dimensional than Bryston.

Or, he has a demo Acoustic Research Ref150. Somehow, I doubt I'd like to go with tubes, due to the sonics, the expense, and the 'hassle' of dealing with tubes.

All of the prices mentioned are more than I'd like to spend, but I've gotta deal with that part of it.

So, I'd love to hear recommendations.

And... how does one audition amps when they live in an area of so few B&M audio stores?

Rhanson. If you read your original post, and please do, you do not mention you had a reliability issue with your amp. You, in fact, make accolades about how wonderful your system was, including the amp, as being part of your system, but, still wanted to improve upon it. You could have indicated, without mentioning the manufacturer, it was problematic and unreliable, and that was the reason for the post. I read your post, and took your post, literally. So did others. I am moving on. Enjoy ! Mr.D.
Mr. D:

Sure, I could have, but I didn't. Get over it, or "move on", because it's no big deal in the overall scheme of things. Your complaint seems to continually stray from the point of the thread.

(I also don't know why my post from 7/10 was duplicated on 7/12. I think Agon burped.)
@Infection --

Actually, I was on the list to receive one of the first run of the PS Audio BHK. Sadly, I had to back off because of a temporary financial issue, but in retrospect, I'm glad that I did. Considering the troubles I've had with the current amp, it is probably best for me not to be one of the early adopters. The BHK was, of course, an unknown beast at the time.

I hear some people love it. I wish PS Audio all the success... they're a pretty remarkable company.

Based on various recommendations in this thread, I've been demoing a pair of Merrill VERITAS mono blocks for about a week. They sound quite good, and are definitely a contender for my new amp.

Later today, I'll be receiving a Sanders Audio Magtech (stereo) to try for a while.

Kryptobrand has returned home and has been tested out.

This should be an interesting weekend...
