My two cents: I have tried several brands of KT88’s in my VAC Phi 200’s and have come full circle back to the Shuguang Gold Aero’s that the VAC’s came with. Very elegant, musical sound with great resolution, superb sound staging and zero fatigue. I also still have the factory Shuguang 6SN7’s which seem to be nice, too! While I haven’t tried NOS tubes yet in these amps, I am confident that VAC is pretty particular about the tubes they use. Plus, their cost is reasonable. I have used some NOS preamp tubes in my ARC SP-10 and my CAT SL1 Signature. British Mullards and German Telefunkens. They certainly are quiet, clear and non-microphonic. Maybe better. I’m not sure. |
I have a Phi 200 also and I dont use any old stock tubes in this unit. NOS KT88s are stupidly expensive and I have found that rolling the driver tubes usually has more influence on the sound. However, Kevin of VAC swears that you need a matched quad of 6SN7s so I use the stock tubes out of laziness. I do use old stock in my line stage, DAC and some of my other amps. |
Shu GA Looks awefully nice,,,but out my budget atnthe moment,,will have to stay with 1990's Shugaung labeled ARC. The Defy takes 12, = huge financial decision. But will consider https://tubedatabase.co/tubes/gold-aero-kt88 Shu WE6SN7 Sweet, and my guess competes with NOS https://www.ebay.com/i/293397411041?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=293397411041&targetid=596465759468&device=c&mktype=pla&googleloc=9025123&poi=&campaignid=6470636538&mkgroupid=81597521470&rlsatarget=aud-622524040958:pla-596465759468&abcId=1140476&merchantid=101678628&gclid=CjwKCAiAu9vwBRAEEiwAzvjq-44USXq61h4O1PlFAWFTXhnjDbxpJiqcXZNH-GKiSycSVV-8yiSnXRoC6gAQAvD_BwE |
