Best Amp for Magnepan 1.7?


What would be the best amp out of the following four brands to power the new 1.7s? Also, would a monoblock setup be worth the extra money? I like McIntosh; however, I'm not sure if the detail and speed will be up to what the 1.7 would want.

Krell
Mark Levinson
McIntosh
Bryston

Thanks guys

Here is a different option for you, and for panel fans...

Read my review of the  Redgum Audio Articulata Integrated. One of the most unusual products I have encountered in terms of design, but the manufacturer is uniquely skilled. This integrated drives the Kingsound King III ESL speakers better than any monster mono amps I have reviewed. Freakish ability to wake up a panel speaker. 

I very much enjoy the Benchmark AHB2 amplifier in Mono (2) mode, but they do not have the capacity of the Articulata to drive a panel so powerfully. I have not found amp(s), tube or SS, up to $25K that outdo the Articulata with the panel speakers. 
I own Maggie’s (3.6) and I went through a number of amps and once I put Mac 501s in the system the search was over for me.

I will not disparage the other amps as I believe in synergy between the components and Maggie’s, Mac SS amp and a tube pre amp are the sweet spot for me.

I recommend trying McIntosh.  FYI, I bought my 501s 10 years ago and can still get all my money back in a sale, not that you could pry them loose from me, LOL.
If you have the scratch get Pass monos that fit your budget and power requirements!
I ran my 1.7s for years with a Krell 2ch power amp, then I bought a Bryston 4BSST cause at the time that’s what Magnepan was using in their demo rooms. There will come a day when I’ll most likely upgrade to a Bryston Cubed amp.
Fully modded 1.7 with external crossover from the good guys at humble hifi, birch wood frame with rear braces and swapped rear panel to front.

Had the luxman 100ux, conrad johnson ca200 and recently a mint ML 23.5 with #26 pre and except the more ballsy bass of the latter after warm up, the wyre4sound sti1000v1 sounded the best of the lot from cold start and runs 24/7.

Think 725w at operating 4ohm of the 1.7 and up to 40A instantaneous of the sti1000 helps a lot.

Hope this helps anyone looking for a cost effective single box integrated amp.
