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 own both tubed DAC and preamp. Definitely a very synergistic combination. In my system especially since both are Audio Research. Absolutely nothing wrong combining different brands.

 

One thing I must comment on is the word “random”. I assume you did not really mean just combining two different brands randomly. But that research into the sound quality of each… and particularly when buying the second is a part of your process.

I definitely do recommend both. Quite honestly when I added my tube DAC… it was astonishing how much more musical and realistic my system got.

There are many great solid state preamps. Nothing wrong, at all, with using one. I still prefer high end tubed preamps. When I have compared similar prices ss and tubed preamps I have preferred the tubed… they have a more natural and musical presentation. There are probably exceptions.

Controlling amps directly from DACs is not a thing yet. Many people have tried it and most have abandoned it. You end up with great details and a sterile sound. I suspect over the next twenty years this will slowly change as digital dominates the market and analog becomes less main stream.

 

But for now, unless you want to put out a lot of money, a lot of research time and probably buy you DAC (non-tube) and amp from the same manufacturer, it is better to assume you need a high quality DAC and Preamp.
