Finally getting down to making a thread about these truly brilliant amplifiers. For me, the VI is an amazing piece of amplifier, driving my T1's with ease and transforming them into a beast that conquers everything. Currently rolling with RCA 6AS7G grey plates in the back and Tung-Sol VT-229 in the front, great combo so far. I also managed to catch a quad of RCA 6AS7G black plates, as there have been rumors that these sound better. Shuguang Treasure 6SN7 replacements are also on their way to me. Hoping to see some tube rolling going and reading your impressions on this, in my opinion, underrated amplifier.
