Amp recommendation for Magnepan 3.7's?

I have a pair of Magnepan 3.7's that I just acquired and currently power them with a Rega Elicit integrated. I am thinking about buying a used Wyred4sound ST-1000 and use the Elicit as a preamp. Before I pull the trigger on the Wyred4sound I am wondering are there any recommendations for producing the best sound from a pair of Magenpan 3.7's?

In looking at the specs for the Magtech, it would seem that they have tons of power for the Maggies. Indeed, that's what they were designed for, hence "Mag"tech.

Roger was quite adamant that there wouldn't be any break-in time on the amp, that with only an hour or two of warmup, they'd sound like the ever would. After a couple of days, I asked, "Are you sure?" He was quite sure. Well, I found the presentation rather flat and two-dimensional, lacking any real involvement at all. Power? Yes. Muscle? Yes. Engaging? No. It played the notes, but... Is that "analytical?" Methinks so.

Based on my own experience, I should've run them up about 300 hours to give them at least a fair shake, but Roger said.....

The Bel Cantos get better as the hours go by. As you might expect, they're young, likely less than 300 hours, so I'm going to give them about another 10 days while I A/B with the Veritas (wicked broken in), and the Rowland Continuum, who the dealer claims is broken in, but I don't know how many hours, exactly.

For what the Bel Cantos are doing, they're a remarkable bargain, with an adorably small footprint.
I should add that I probably learned more from Roger Sanders in a few emails than I have from a week of poring over posts and reviews. He has a wealth of knowledge at his fingertips, which aren't afraid of typing at all. He was quite helpful in sorting out any number of things.

He also offers a risk-free trial, so if anyone is considering these powerhouses, you can't go wrong at all. 30 days, shipping both ways, prompt and personalized attention.
Pass 250.8 wonderful sound,great dynamics,bass,airy highs and sweet midrange.
Rob, thanks for sharing your further perspective! I recall reading a review of the Magtech amps which came to the same conclusion as you, maybe you should be a reviewer. I haven't had the opportunity to hear the REF600M amps yet, so I find your experience with them of particular interest. BC replaced both their 500M and 1000M models with the 600M even though the 1000M amps were more expensive.
