Mesa Baron


Not a question, really, just looking to share something with any users of the Mesa Baron all-tube power amp (now sadly discontinued).

I just found THE preamp to match this high-gain amp, after trying for 10 years. It's the Promitheus Audio TVC (passive transformer volume control).

Over the past 12 years, I've used the Baron in 3 phases - back in 96-97, when it first came out, when I reviewed it for a publication; then in 2000-2001 when I bought and then sold one ... and finally, in 2004, which I intend to keep until Hell freezes over.

I've used McCormack's passive TLC-1 preamp (a pretty great match), Audio Research low-gain LS15 and LS16, Quicksilver Linestage and many others ... but something just clicked with the TVC.

Just in case anyone's still in the hunt to optimise their Baron's performance. Do note - all the while, I've been using the stock version. I have, however, messed around with the input driver tubes (AX7) - the onboard Russion Sovteks have the best punch, Tungsols sound cleaner and airier, and Mullards are just too syrupy for me ... :)

Appreciate any thoughts ...

cheers

I'm trying to get my Baron to synergise with a pair of Magnepan 1.6 speakers I just got, but not quite hitting the spot so far. I sold my first Baron because, driven by an AR LS16 preamp, it didn't quite do it with my earlier set of Maggies (also the 1.6). Looks like I've come a full circle now, although the bit players are different this time; for one, it's the Promitheus TVC passive pre, and Anti-Cables, and different power cords.
It's been a while, but here's something I finally hit on. I had put the Baron aside for a few months, also sent it for a service (one of the meter bulbs had blown). In the meantime, I got myself a McIntosh MA402 power amp and more recently, a C220 tube preamp.
When the Baron came back, my thought was to sell it, since the Mac pre-power was so musical. Anyway, I hooked the Mac pre to the Baron and voila! I was blown away, sounded like a perfect match for the Baron. I never heard it sound better.
So, it stays ... :)

Just thought I'd share.
Have a Mesa Baron with Tesla EL34 blues, Hovaland Musicaps, hexfreds and Caddocks. Usually run it in triode, still a match for anything around.
I like to run my Baron in 2/3 pentode, 1/3 triode mode. Yes, the triode mode is sweeter sounding, but i need a bit more power to drive the Maggies. In full triode more, bass can be a bit soft ...
The original caps in the Barons were leakers I read it on a forum so I contacted mesa about it and it was actually true.When I flipped amp and took off bottom plate low and behold they were leaking and had them replaced.Great amp though but have since sold
