Tube or SS DAC/Player with Tube Preamp?

I'm on my third set of NOS tubes for my DAC, and the sound is dramatically different with each set. In many ways, this might be the best feature of a tube DAC, but it does mean that you commit to spending a bit of time (and money) fiddling with it. Still, with the right tubes in the right equipment, the sound can be magical.

I have tubes all around in my system and I think that Sean might be right in saying that it may be too much of a good thing. My current quest is to find a somewhat tighter sound than I have now, and I do think that someplace down the road there may be room for a SS amp or DAC. But...with a few more tubes on the way, and a couple more cable designs to try out, it may be a while before I'm finished playing.

Cheers,

I enjoy tubes in my pre-amp and mono-blocks (Atma-sphere). However, I am using an Accuphase DP-75 CD player and am struck with the musicality of this SS unit! I think that at times, we're all hung-up on what is trendy rather than HOW IT SOUND IN MY SYSTEM! Will a $2000 tube amp sound "better" than a $10,000 SS amp? Probably not! Will a tube amp having a mediocre design with standard grade electronic parts sound better than an exceptionally designed SS amp with premium grade electronic parts? Same answer! Don't forget, tube amps can be impossible to match with many speakers, and S.E.T.'s usually are not known for great bass control. Let your EARS (and your wallet) be your judge!

YOu currently have a very neutral tube preamp in the SF2, so I wouldn't be too weary of using a tube dac section. That stated, swapping out tubes in your preamp may be more forward in getting the sound characteristics you like.

As for a DAC or CD combo? $2,000, no problem, do you mind having money left over?

My experience with tube dacs has been positive. I have a CAL Audio Aria in a bedroom system which is tubed and I have demod the Cal 24/96 Alpha dac and a friends Sonic Frontiers CD1 (for sale now) all very nice pieces, but I'd rather point you to a real gem that's solid state

THe EVS Millenium II Dac at $1050 has the most neutral sound and incredible detail. Ric at tweakaudio.com is a real pleasure to deal with and offers a 30 day money back guarantee. His DAC upsamples and has a hearty power supply. He sells at wholesale prices and really has a passion for developing high end audio at reasonable prices. I'm still burning mine in, so I'll hold back on my comments, but have been very impressed so far. Check out the reviews at audioreview.com or do a search here or at audioasylum

Transport? A Cal Audio Labs Delta is an excellent choice and can be had used for around $400

there's still plenty of money left over for the connecting cables and some new cds

I prefer to limit the number of places where my sound can be colored as much as tube rolling can do. Hence, with the tube pre (a fine choice there, by the way) you've got the key place to control your sound with tubes. I disagree with those who intimate that ss cannot deliver good sound - it can and does (I always thought highly of Bryston, by way of example). But it does reduce your sound tweaking options, a fact some find useful and others find restrictive.

So I can't give you a direct answer to your question, because I don't know what you want to do - is it part of the fun for you to fool around with your sound by tube rolling and cable swapping, or are you trying to obtain a specific sound from your system? For the former, go tube DAC or player, for the latter, go with the best SS you can find. By the way, what are you using for a CD source currently? Maybe you could up the budget on the DAC if you kept your current source (if it has reasonable digital out)?

Since technically SS output is matched with any input impedance I would go for SS. It is not guaranteed that it'll sound better than tube since we all have different ears. On my opinion most of the tube designs have colouration of sound rather than details. Some people like it some people don't.
