Bruce Moore Tube Amps

Hi Guys,

Thanks for your interest in the products!!!

To answer the questions:

Bruce has been building this new line of tube preamps and amps since 1992, but most of the equipment has been sold over seas for the last several years. After filling an overseas order, any extra units that were built were sold by a few select dealers. Since the slow down in over seas sales in the last 2 years, I do sell as a dealer and distribute to other dealer.

I do have a demo program for customers and dealers for evaluation. FYI products can be seen on the web site: www.rbaudio.com

Any questions e mail bergner@pacbell.net or call 925-918-3714.

Questions on using different tubes in these preamps and amps please contact me for details!

Sincerely.

Bob Bergner

Gunbei: You can use either 6550 or KT88 output tubes with the Dual 70. I am using the 6550's that were shipped with the unit. Bob @ RB Audio suggested that I keep the 6550's since they sound smoother than the KT88's (my Martin Logans tend toward the analytical side). I did try JAN Philips NOS 6922's for the input tubes. The two outside tubes, of the four, make the greatest difference in the sound according to Bob. They sounded good, but I am sticking with the stock Teslas for now. I do have JAN Philips 6922's in my Companion III preamp and they sound great.

Thanks for the info Smerkle. As I get deeper into this hobby I'm starting to find that I like resolution and detail, but not at the price of musicality. It sounds like the Bruce Moore line might be a direction I may be taking. Once I get the cash. Thanks for tube rolling tips.

No problem Gunbei. You won't regret your choice if you go with the Bruce Moore gear!

This response may be a little late but I just recently purchased a Bruce Moore Dual 70 power amp and I wanted to add my impressions to this thread. I am in complete agreement with Smerkle regarding this terrific tube amp. After putting the Dual 70 into my system everything opened up musically. I could go on about greater depth, improved details, and richness of tone, but my greatest impression has been a profound enjoyment of music. I am trading sleep for late night hours with Ella, Sinatra, Basie, Coltrane, etc. Earlier on, after purchasing a pair of Talon Raven speakers (another great product) I was left feeling I was not getting the performance these speakers were capable of. Changing from adequate solid state to the Bruce Moore tube amp made these speakers really sing. This combination has been addictive, particularly with my analog rig. As Smerkle noted, you don't hear much about Bruce Moore products but they are well worth checking out. I also look forward to upgrading to the Bruce Moore preamp when the new model comes out with a phono stage. I purchased my amp from Bob Bergner at RB Audio. He is really an honest and good guy to work with. If you're in the market for a tube amp that has the magic that tubes seem to provide in the highs and mids but with balls on the bottom end too, and one that does not cost an arm and a leg, you just might want to give Bob a call. I'm glad I did.
