Best tube dac available?

Typo, I meant Sksos1.

Besides the Bricasti is a SS Dac and the OP is asking about TUBE Dacs.

Like me, he may want to pair a tube Dac with SS amplification, to get the blend he likes.

wisnon ~ Yes I understood what the OP was asking but since I had some experience with a tubed DAC (and also an AYON tubed dac) I just threw in my 2 cents worth. And while the BIG6 was wonderful I'm sure the more expensive Lampi's sound better, they should but I never heard one myself so can't comment. Also the OP didn't ask about tube size so the age old question remains....does size matter!

Skos,

Yes, size always matters. LoL
