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?

I’m totally on board with the idea that a tube dac can work well with an excellent preamp. I’m currently using an Aqua La Scala with my ARC REF6 and have no issues.
As far as tubes go- I’ve had great luck following the advice given from Brent Jesse. I’m currently running NOS Telefunken red tips w/ wing shape plates- great tubes!

Doge 7 Tube DAC is great. Have owned, Dac 1, Berkeley Audio, Hegel, Chord, MSB and more. This one sounds the best by far.

 

 

I've never had a tube DAC, per se (where the tube amplifies signal). But I have had tube buffers, both external and internal to a DAC.

In my experience, a well designed and implemented tube buffer can add to the sound quality of a DAC, especially when the stock tube is replaced by the best quality NOS tube available for that design. In my current DAC, the MHDT Labs Orchid, the stock buffer tube is a GE JAN 5670W. Well after overall burn-in was completed, I got a nice sonic bump by rolling the stock tube to a WE396jw. But when I got an adapter that let me use a Mullard CV5331, that was sonic paydirt.

An already very good sounding DAC got even better.

So I'm a believer in tube buffers...

Right now, listening to Qobuz through Bluesound to Musical Paradise tube dac to a Yaqin tube integrated to a pair of Forests,(secondary system). I wouldn’t have thought I’d be getting the sound I’m getting with such components but there’s amazing frequency range, plenty of depth and air, it’s amazing. No rules.

If you can run a tube preamplifier with tube amplifiers then why not a tube DAC? Makes sense to me, although I have not heard that combo but my gut says it should sound great. Of course synergy between manufacturers will always be an issue to be aware of, so if the first pairing does not work out well keep trying, I am confident you will find that correct combo that brings heaven.
