Wally, I know you're familiar with SFI gear, cause I bought a pair of amps from you. As you might know I also have the whole 3 line of SFI (T3/P3/L3) -and soon in a month or so when I get them- Power 3. I have been using them for few month now and happy with them. But my amps are the 7Bs and speakers are the ML "ReQuest". As you can in another thread, this combination is not perfect particularly in the highs (too edgy specially at high volume). Now, I was thinking to upgrade the tubes in the Line 3 preamp. SFI tech recommends the Valvo ECC88 to replace the Sovtek 6922s. Others recommended the Amperex 7308. Or shall I wait for the amps to come? Also what upgrades would you guys recommend for the Power 3 if any. The same question I would ask the guys of Upscale audio whom I heard some good things about their knowledge on the web.
