Thanks for the tip. I'll give it a try.
Hi Scot, I just wanted to let you know that I tried setting the bias to 5mv with my Amperex 7316 tubes. I didn’t notice a big change in the sound. However, I am probably one of the worst people for this experiment. I have really bad aural memory and as a result I dislike doing A-B tests.
I may try it again, after all, it’s free. I don’t doubt that you heard a big improvement, there are just so many variables involved with different systems and ears, that I’m more surprised when people agree.
If you get a chance to try the 7316 tube, do it. I really like this tube in my BHK preamp.
