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 to disagree with you on this one. In my experience I have not heard one tube that doesn't change over time sonic wise, normally 50-100 hours so I feel you are missing out big time. Heck it tacks 40 minutes for most tubes to be stabble!

My 2-cents worth anyways

Hi Fplanner2010, I received mine and just installed them. I will share my results in time.

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!
