I think you probably have the best 6SN7 tubes for your Phi 200, given your sonic preferences (I like a slightly richer sound, so I use NOS RCAs, but Andy Bouwman of Vintage Tube Services, who sold me the RCAs, recommended the Sylvanias if I wanted a cleaner, more transparent and detailed sound). I have had no problems (shrillness or otherwise) with the sound of the KT88s VAC sold me, using the RCAs.
Best Tubes for VAC
Hi All,
I've got a VAC Signature iia SE linestage (upgraded from iia) and a pair of Phi 200 amps. I'd like to optimize tubes for transparency and detail (of course I also want tonal accuracy, soundstage and imaging). I'm wondering if there are any folks out there who have optimized tubes in their similar VAC units? The tube compliments are:
PREAMP:
2x 12AU7
2x 8416, 7308, 6922, E88CC, ECC88, 6DJ8, (or 12DJ8 twin triodes)
AMPS (each)
4x KT88
4x 6SN7 (in the best 2 positions, I've got a pair of NOS Sylvania 6SN7GT's)
What have people found to work best in these VAC units? Thanks in advance, Peter
