Tubeguys:How much "tube sound" from tube players?

Foster_9, Sorry, I forgot to answer your question. IMHO what you seek from a tubed CDP will be lost with out the benefit of a tubed amp. With my present stuff I vastly prefer the combination of a SS CDP (Wadia) with tubed amps (Sonic Frontiers) than a tubed CDP (BAT) and a SS amp (Muse). The Wadia into the Muse was a poor combo whereas the BAT into the SF stuff was fine. I'm sure different equipment combos would produce varing results and YMMV but thats sums my experience.

Newbee's comment,

"It is probably far easier to get a SS preamp that is neutral and not subtractive, than it is to get a SS amp that will ever sound like a tube amp.",

caught my attention.

I have the CAT JL-3 mono tube amps. Each of these uses 16 6550 tubes and 3 small-signal input tubes. A Rowland ss amp sounds more tube like than these amps.

I would like to point out here that Newbee runs with THE greatest preamp from the 1980s .... the ARC SP-10. The stock SP-10 is indeed a very subtractive product, but a wizard like Steve Huntley no doubt could resolve a lot of this through many component updates. But even without such refinements, I am sure that this unit's awesome portrayal of space has everything to do with why Newbee owns this. You are not going to find this in an ss unit.....I have tried and tried with no success.

I suspect that if we dropped in any number of other tube amps from VTL, Manley, Atmasphere, etc., in place of Newbee's current tube amps, the sound might be even more rich and full and "tubelike". But if the stipulation was that we could only do this if we also replaced his SP-10 with any number of ss preamps such as ML, Pass, Classe, Klyne, etc., even the super expensive Blowtorch, you can be sure we'd see a sad sad face as we walked the SP-10 out the door. I really do not think this would be so easy to do...but who knows. And if we dropped in a more refined tube preamp like the Aesthetix Io/Callisto and ss amps like the Plinius Rowland or Gryphon here, .... well, .... , you get the point. And again, the amp/speaker interface is critical.

Foster_9: I have not heard any of the latest offerings of tube DACs or CDPs. So many Sony and Denon players are being modified with tube output stages and these are getting high praise by all that hear these.

I have been running with a Manley Ref tube DAC that uses 2 pairs of tubes. This piece brings my CD playback closer to my analog setup than any other I have yet heard. The piano especially is just magnificent. The Audio Aero in my system was a bit more refined but to me lacked that last bit of magic of the Manley.

Like many of the products from a decade ago, the Manley has some problems at the frequency extremes and the ultimate in resolution. But Steve Huntley at GNSC has recently improved this unit far beyond what I ever could have expected. This would now crush such a player like the Audio Aero. I still hope to get this running again here soon.

But even with the magic that the Manley DAC brings on, the ss DACs that I have heard here such as Counterpoint DA-10, Electrocompaniet ECD1, Muse 296 and Classe DAC1, into my Aesthetix Callisto line stage would all outperform the Manley into a ss line stage. I have no idea why this is, but the line stage continues to be THE most critical link in terms of retaining the 3-dimensional view into the performance.

John, I'm amazed that you find the Rowlands more 'tubey' than your CAT's. Are you just referring to tone, that is the Rowlands are warmer? I'm dying of curiosity why you would be buying all those 6550's if otherwise. :-)

I suspect that you are using the description of the effect of tubes differenty from how many would define 'tubey' when comparing the CAT's and the Rowland, vis a vis the last sentence of your post, which is my definition of one of the effect of tubes which is for the most part missing from SS devices.

One of the reason's I recommended consideration of a well implemented passive line stage is, assuming comparable quality of the attenuator, you need only match a good (assumably tubed but not necessarily) CDP with your chosen tube amp and speakers.

In the end its all about synergy, speaking of which - While the following combination of equipment would hardly rise to your expectations on either a tonal or resolution quality basis, and frankly surprised me as well, I recently combined a Wadia 302 with a Primaluna 3, the SFM's and my Tylers. The net result was excellent resolution/imaging, warm tone, full tight bass, and totally non fatiguing to listen to. It was most impressive with a solo piano when listening to the bass/lower mid-range to hear clearly all of the impact of the piano AND clearly hear all of the decaying resonances from the sound board as well as the wooden body of piano and the acoustic. So many times what we get is either too much bloat from slow rise times, too much resonance from slow decay, or the opposite. Since putting those components together I'm seriously re-evaluating what it is that I think I need from my system beyond that sound. If it were not for the phono stage of the SP10 I think both it and the BAT CDP would be retired. Now, after that admission, no one will ever take me seriously again! :-)
