    I just got one of JJ's new ECC803's in the mail today, and decided to A/B this with the JJ, Tung-sol and Electroharmonix 12AX7's.

    My setup was a DB659 (v1 variable, v2 JJ 12ax7) into a Samson sx1200 into an Accugroove T112L.

    All are good, warm and defined; but the ECC803 stood out as very defined and hi-fi. The only version they are making now is the gray plate (the silver plate didn't perform as well), and this is supposed to be their counterpart to a Telefunken 12AX7, but warmer and smoother.

    I'm actually surprised at how tube differences come out on the DB659. It's more significant than with my Groove Tubes Brick

    I actually just got in two ECC803's and two Tung-Sol's, too! :)
    The DB 659 seems pleasantly very tube tube sensitive to me, too. I like it! :hyper:

    I'll have to try some of those JJ's in my Dem 201S.

    Thanks for the head's up.

    [temp off topic]
    Hey, TBowlus, have you tried running the Berg IP's with your 201S yet?

    I know the passive Berg cabs really like the Dem front end.

    Its must be nice to have infinite combinations of gear. I should take time out to figure out how many possible combinations of basses, preamps, poweramps, heads, and cabs you have...

    Okay, this really deserves its own post, but here goes. (I haven't done math in a while, so it may be off:) )

    Basses = 31
    Combos = 7
    186 combinations of basses and combos

    Basses = 31
    Heads = 23
    Cabs = 51 (Different types, this isn't even including doubles or using multiple cabs)
    36,363 combinations of basses, heads, and one cab

    Basses = 31
    Preamps = 27
    Power amps = 7 (once again unique power amps, not including doubles)
    Cabs = 51
    298,809 combinations of basses, pre's, power amps, and one cab

    335,358 possible combos of Tom's gear!!!

    We would need a 3 year long GTG to try all of that out...lol

    Thats if he only runs 1 cab per set up, and 1 power amp per preamp. So its actually a lot more. I'm too lazy to figure it out right now, you'd have to account for the loads that the power sections can take, the impedances of the cabs, and the number of outputs of the preamps, but i'd take a guess at between 2 and 5 million. And of course, if Tom uses a signal splitter to go to more than one setup, he has a hell of a lot more options.

    It's really a beautiful preamp, but looking inside, I can't see why it is so expensive ... there's not much in the box. On the other hand, it works and I can't complain.

    I can't complain about the Samson either ... I picked it up because my TFB550 went to the shop ... the Samson was $300 which is an incredible price. It's a bit heavy (there is a huge toroidal transformer in the center of the box) but otherwise your standard non-coloring power amp

    Yeah thats why I just kept it simple. When you talk about multiple cabs, and the fact that he has a custom series to parallel y cord cable, and the fact that he has multiple big power amps, the true number is infinite!
