I had thought the same myself. Can tubes cancel each other out? Tubes are in the chain to achieve a particular sound signature you like. This is the whole idea behind tube rolling. There are tube dac tube phono pre amps and tube amps snd tube pre Amps that can all be in one chain. Every link in the chain will effect the output sound. This does not necessary make it bad but would need slot of adjustments. My biggest concern is that most tube stages add gain into the signal path and if you are adding gain of 12 + 14 how much distortion can be you end signal or output. I like the flexibility of my Freya pre if I had a tube dac I could take the tube stage out of the pre amp. Currently I have Gustard R26 non tube dac do use tube stage on Frey’s with nos tall boys. I still hope to some day find the holy grail Telefunken nos tubes and not have to pay a $1000 each. Have fun exploring and enjoy the music!
Tube DACs
For some time I've assumed that tube DACS are meant for direct output to power amps -- in other words, no reason to use a tube DAC if you are running through a tube preamp (unless all components are by same mfr and designed for synergy).
But lately I have seen posts implying some run Brand A tube DAC through brand B tube preamp -- say, Primal Luna 100 to Rogue RP-9. Can't find any prior threads addressing this topic directly.
So, question: am I wrong to suppose that pairing random tube DAC A with random tube preamp B is a bad, or at least a silly idea, absent a known synergy?

@bigkidz What is the link to your company's website? |
@macg19 I saw you recently added a Black Ice tube DAC into your system and mentioned rolling in Mullard tubes to really increase it's sound/performance. |
@amtprod I got the Mullards (and others) from Brent Jesse. Go to audiotubes.com Brent is a guru, let him know Ian sent you (wont save you or me any money but it would be nice) Best way to get a hold of Brent is email. He is busy and short handed. The Mullards were expensive, $450/pair (1950s halo getter long plates). Brent also recommended "Brimar military CV4035 “flying lead” 12AX7 modified by Bob Hoviland for use in a 12AX7 socket". I think these are $350/pair. I have relatively cheap Brimar’s in my tube amp and they are wonderful - I’m a/b testing these against a much more expensive Mullard’s right now and so far the cheaper Brimar’s are better but I have many hours to go before making a call - the Brimar’s have a lot more hours on them than the Mullard's. Dave from Raven Audio also suggested Amperex & Valvo (ECC83). Brent has these and lists all prices and in-stock items online. These tubes were recommended specifically for the DAC - ZERO noise / microphonics. Brent will allow a trade-in if you dont like what you get - no re-stocking fee if you apply the full purchase price to another tube. I’d give the Brimar’s or Valvo’s a try first.
