Which 6550's should I use? What is better than 6922's?
Will the KT88's make my SF power 2 sound warmer and smoother highs compared to 6550c's that I'm using now?
I am thinking about buying 2 quad set of Gold lions re-issues
or Tungsol 6550 re-issues.
thanks
I will start with the driver tubes first. thank you
How about the SF line 2 pre, it sound a bit lean compare to my Adcom. I have 6922's any other tube you can recommend? Thanks Again
