Audio Research Preamp Experts?
Minor1, SP-15 is different, no tubes in the line stage. SP-11 MKII is the better choice. 
Audio Research Preamp Experts?
Are you going to buy an Audio Research amplifier? Some ARC preamps work better with certain amplifiers. The earlier tube units like the SP-8 MKII and SP-10 seem to work best with ARC tube amplifiers. I disagree with earlier posts. These older tube... 
tubes and moisture
Lapierre, Excellent suggestion. From everything I have read the best all around humidity is 45-50%. 35% is too low and 55% can be too high for certain instruments like a piano. 45% is a good number to shoot for. Its good for you, your house, any m... 
I need a lower gain 12au7 for Mastersound
I believe RFT is what came with my Mastersound amp. Although my amp used different tubes. 
I need a lower gain 12au7 for Mastersound
The 12AU7 is the lowest gain tube in that family of tubes. The problem is not the amp. The problem is between the speaker and the source. 
I need a lower gain 12au7 for Mastersound
Are you sure those are preamp tubes? Mastersounds claim to fame has always been their passive gain stage. The 12AU7 tubes are drivers for the output tubes. Using one of the low gain alternatives will result in a very dull sound. Apparently yours i... 
Best Subwoofer you've ever heard???
Vandersteen subwoofers are one of the best I have used and they have a unique way of integrating with your main speakers. Maybe not the deepest bass, but deep enough and very musical. Highly recommended for music with three eight inch drivers in a... 
speaker types and biwire
It depends on the design of the crossover and not all speakers with two sets of binding posts have crossovers designed for bi-wiring. I'm sure a lot of what you heard was in the better speaker wire. 
Audio Research REF 3 and REF 5 Tweaks
"the addition of Herbies tube dampers really cleans things up."Really, you cleaned up the sound of your Ref 3. 
PSB Alpha B 1's
Another good inexpensive speaker is the Paradigm Titan. I have played around with the Alpha and the Titan and I like them both. 
Where do you have your rack?
Tim, Can I make a recommendation? Your room is not balanced. The left side has bookcases with plenty of diffraction and the right has uncovered windows (reflective). Remove the room treatment and install some window coverings to try to get some ki... 
Trade- off, power SS vs tube magic.
"it's called tubelike if it's SS and vice versa."I don't think I have ever heard someone say this tube amplifier is the most solid state sounding yet. 
Where do you have your rack?
The reason for not placing your rack between the speakers has much more to do with sound than convenience. I get the impression your long interconnects are not as good as your other interconnects. It might be time to upgrade your long interconnect...

I suppose Upscale Audio has some decent tubes, but the service isn't what it used to be. The people on the phone are not that knowledgable and they refused to take my order over the phone.

Roger Modjeski has them at a reasonable price.
