This amp has a cult following. It is soooo powerful, yet has so many different voices.
You can run it pure pentode, pure triode, or different combinations of the two (and switch on the fly). 4 different modes of feedback. AND then there's so much you can do with tube rolling. I have 5881 (6L6) outputs as well as new EL34 Wing-C. Also has user selectable input impedance as well as single-ended and balanced inputs.
This amp had no problems pushing IRS Gammas, as well as my Infinity RS-1 panels (and many other speakers). Gobs of tube power for Maggies and other hard-to-drive speakers. This is a true dual-mono amp; it even has dual upgraded power cords!
If you are reading this far, you already know about the Baron and want one. I bought this one from the original owner that lived near Mesa's factory. Needless to say, it's had all updates/caps/tri-tube already done to it at the factory.............. I have many pics and can email them to you if you are serious.
My 6/10 rating is consistent with A-gons scale. That said, the scuffs/scratches are pretty much relegated to the front handles and 'roll bar'. They tend to take the majority of the hits on the Barons. The face itself is easily a 7 if not an 8. All in all it is very presentable with a few scratches on the protective rails. If one were interested, they could be removed and repainted matte black. All lights and meters work as they should.
I have the original shipping box, so shipping this beast safely should not be an issue. The internal of the box is blown-in foam. I cannot remember if the tubes were shipped in a second box, but either way, it would be a good idea considering the minimal additional cost. The OEM manual will be included.

"The Baron is a fantastic amplifier at a very reasonable price." Bruce Manoly, Positive Feedback
"One of the best sound-for-the-dollar components in high-end audio today." Mark Block, The Audiophile Voice
"Seductively sweet-sounding." John Atkinson, Stereophile
"It's as close to what I'd imagine an all-valve Krell would sound like if Dan D'Agostino ever got a jones for tubes." Ken Kessler, HiFi News and Record Review
"Knocking, no pounding, on state-of-the-art's door... one of the best values in Audio." Tom Miiller, The Audio Adventure
"The Baron fills my sonic wish list as beautifully as I could have hoped for: Transparency, high resolution, tonal neutrality, liquid midrange, soundstage depth, extended but sweet highs, powerful yet controlled bass." Mark Block, Audiophile Voice
"It's only serious competition comes from amps costing two or three times as much." Dick Olsher, FI
"The Baron entered this household under the least favorable of circumstances: it followed the $ 30,000.- Audio Research Reference 600 power amplifier... That's a tough act to follow, but - even with its more earthly price, the Baron damn near stole the show!" Tom Miiller, The Audio Adventure
