Some good advice here from @tpreaves @lowrider57
I agree that you need some more time on your tubes.Don't be in a hurry to start changing things.
Octave Audio V70SE tube recommendations
Hey there!
just recently jumped into the vacuum tube gear. Purchased a V70SE, Looking to start tube rolling, and wondering any of you octave owners can provide some recommendations for tube replacement. I currently have stock (4) JJ 6550 output tubes, and just installed drivers tubes w/ (1) RCA 12ax7 1950’s black plates and (2) RCA 12 au7 old stocked matched. Current system sounds a little bright or tinny. Perhaps tubes need more time to break in? (About 20hr so far), or I need to replace the output tubes. currently have dynaudio heritage specials, Linn LP 12 and DSM for streaming. looking for a little warmth and a bit more bass ( would like to avoid a subwoofer), w/o losing detail. Mostly stream when playing background music, then switch to vinyl for serious listening. Any guidance would be appreciated.
Best
