Audio Research Ref 250s for Magnepan 20.1s?


OK, I'm thinking about taking the plunge into large tube amp, upgrading. Will the ARC Ref 250s have enough power for the Magnepan 20.1 speakers? Anyone using this combo? The Ref 750s seem too far out there for me but I would like to hear if someone has experience with either of these? Right now I have ARC Ref 3 preamp and Ref 8 CD player along with Pass Labs XP25 phonopre, VPI table with dynavector cart, and Pass Labs X600.5s. I have plenty of power but had an eye opening experience with a friend's Cary Audio 60 watt triode stereo amp. Nowhere near the power needed but it had qualities I desire such as midrange bloom and wide soundstage without harsh upper end. It was bass shy but I do have Nola subs. Should I sell the pass 600.5s and get ARC ref 250s? or 750s (god forbid)?

If you like EL34's, you might consider Wolcott 220's. VTL 750's would be great with the Maggies - the older models are more affordable.
They did a great job of driving the 20.7´s at a show in Sweden a couple of weeks ago but according to the dealer the Lamm M2.2 is even better.
The Pass XA.5-amps are also considered a great match.

If you buy Refs be sure to have a significant budget for replacement tubes.

MG 20.1s require biamping to be at their best, which is often overlooked.
I don't think the ARC Refs have the sound you are looking for: "qualities I desire such as midrange bloom and wide soundstage without harsh upper end." They do not have the traditional "tube sound".

In general, top of the line tube amps probably sound more like your Pass amps than the Cary.

You might want to keep the Pass amps and experiment with lower priced tube amps from conrad-johnson, BAT, McIntosh, Quicksilver, Rogue, Cary, etc. until you zero in on the sound you want and then spend the big bucks for the big power.
Hand made in the USA, all point to point wiring, USA, 2 ohm tap, easy to bias, runs fairly cool for a tube amp, 7 year transferable warrantee.
