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?

Thanks for the recommendation for Reno. And Guido, your posts are most helpful.

As for power (please help me understand), we don't play at very high volumes, and nothing to heavy, raucous, or driving. Well... Bonamassa might be an exception. Is that "moderate rise in power" at 4 really much of an issue? How would the effects manifest, and what differences could I expect going with an alternate amp?

As I've said, I'd really prefer not to buy a new amp, but this one is back for repair... Again. I also fear for the future of the company, as things have changed radically there.

Hi Rhanson, in most cases, you would observe that bass control is sub-optimal, and dynamic of transients are less than realistic... You also migh have to raise volume on theamps or DAC higher than what seems reasonable in order to get desired gain.... Your amp(s) might end up working harder than they should, lowering their reliability.


If you were experience some unreliability from the amp, it might because it works too hard to drive the 3.7s.

Neither the Merrill Veritas nor the Rowland Continuum S2 would suffer of this problem... They are made for compatibility with speakers having variable or lower impedance.

BTW, I tried to send you a PM, but did not find a link for that in your profile page... Want to try from your end?

@ Guido -- That's insightful.

So, please recall that I'm using Vandersteen 2wq subwoofers. That should take a lot of the bass load off the amp, as these are powered subwoofers. Could that still be making the amp work too hard? I had always been under the impression that this was a powerful amp with plenty of headroom.

I'll check the PM thing.

Re: PM. I have a PM in my inbox from another Agon user, so I don't think that it's anything on my side. I could be wrong.
