Has anyone compared the Sophia Electric 6SN7 tube to the Synergy HiFi 6SN7. I have a pair of modified (by Bill Baker of Response Audio, Purity Audio fame) ASL Monsoon mono bloc amps and there are two 6SN7 tubes per mono bloc. Eack mono bloc has a 6SL7 tube and four KT88 power tubes as well. I am currently running Genalex Gold Lion re-issue KT88 tubes.
Thanks!
