The Shugaung Black Treasure 6SN7 equivalents sound excellent in my Ren 30/30 amp.
Best tube rolling options for VAC Ren MkIII preamp
I have read most VAC threads on Audiogon and pieced together some information on tube rolling for VAC 300.1a and VAC preamps (Renaissance Mk III is what I own). Was hoping to get in one thread others' experience/POV/advice on what the best tube swapping options have been for their VAC gear, or other high end amps/preamps that take similar tubes (e.g., 12AX7, 12AU7, 6sn7), or if stock tubes from VAC ended up being the best choice. Thanks in advance for any insights. If I'm missing an definitive thread on this pls redirect me.

Podeschi, I have some Ken Rads, are they all the same? Can you send me some pics to [email protected]? |
My Recently added seimens 7308s into my Ren sig mk2a made a huge. Difference - deeper and tighter bass, more extended highs, etc. Overall a much better, well balanced sound. Wouldn't have believed it out of 2 tubes. Added Black treasures as the front 4 tubes for each 300.1 about a year ago. Got slightly sweeter,more extended highs. Good luck. |
Hi Fplanner2010, okay some initial thoughts with these 2 tubes in my pre. Most defiantly you can hear a difference from the get go, yes I agree the bass is tighter and deeper, highs are extended and are actually clearer. Would not know this was possible until having placed such in my pre and actually hearing the differences in person. The floor noise has dropped also, more focused. Will put in some more hours and then place back the original ones to compare, amazing what two tubes can do :-) Thanks again! |
