NOS tubes for Sonic Frontiers Line 1

Jim:
I have not owned the SF Line 1, and connot comment on the specific preferences of that pre. However, two good places to look for info about and comparisons of the various memebers of the 6DJ8/6922 family are:

I don't know the tube complement of the Line 1, but if it includes 12AU7's, IMO, Joe's discussion of that family is a bit short. There are other more detailed threads on AA.

Jim:
I am glad you are enjoying your first steps into tube enjoyment. It can be quite addictive. I fully understand your feelings about White Label USA PQ's, which are the next on my list. I currently have Holland Bugle Boys and Holland Orange Label PQs. Comared to what is considered "the really good stuff", the White USA PQs are actually quite reasonable in price. Enjoy!

Jim:
Forgot one thing......based upon my experience I have found absolutely wonderful benefits with tubes using good isolation and dampers. I am currently using Townshend Seismic Sinks (need one more for my pre) and Herbie's Tube Dampers everywhere there is a bottle. The benefits of the Sink under my tube DAC was absolutely eye opening. Can't speak for your equipment in terms of reaction to dampers, but in my pre (a PSE HL1) the improvement wrought by putting the Herbies Dampers on a pair of Holland Bugle Boys was really dramatic.

Jim:
Please post your observations when you get the Herbie's Dampers. I am interested to hear how you like them and what changes you observe.
