Tube cdp's and Tubed Output cdp's


I don't know much about cdp's that use tubes and I'd like to understand more about the. Thanks in advance for all your helpful information.

My first question is, what types of tube cdp's are there? (i.e. Tube cdp, tubed output cdp)

Second, what are the advantages of using a tube cdp vs. a ss cdp?

Third, if you use a tube cdp, do you have to let the tubes warm up before using it to listen to music?

Thanks again for all your responses,
Mike

I'm currently using a Level 1+ Music Hall CD25 that was modified by Part Connexion. (Goes into a Sunfire preamp and Sunfire amp to Klipsch Legend series speakers.)

I have recently switched to NBS Master III speaker cables which have really brought out the midrange and have tamed the brightness of my Klipsch speakers.

My objective: Improve the midrange and clarity even more and make the sound smoother.

The only tubes in CDPs that I'm aware of are in the analog/output stages of the players. In the early days of CD, the use of a tubed output stage often had the nice effect of taming some of the digital "glare" exhibited by the early players and CDs--my Analogic Designs (Scott Nixon's original company) CD player may not have had the hyper detail of the Magnavox 472 on which it was based, but it was FAR more listenable and enjoyable for music. As digital and CD players have evolved, the use of tubes in an output stage doesn't necessarily "soften" the sound (although it certainly can, depending on the design and tubes used), but on well-designed units has a three-dimensional palpability to the soundstage images that most solid-state dsigns still don't quite match, in my view. They may not quite have the control in the deep bass of solid state units, but they have good quality in their bass reproduction, and depending on the tubes used might have a lusher midrange. These are generalizations, though, and not true in all cases. You do need to let the tubes stabilize before listening to music, but it doesn't take that long, and there is a period as they warm up that the sound will continue to improve. I tend to leave my tubed DAC on for long periods, because it usually takes a half-hour or hour for it to sound its best, as with most tubed equipment I own.

If there's any way you can listen to a Shanling CD player, either at a dealer or through a friend, it would be instructive because, at least in its original version, it had both solid state and tube analog stages, each with its own set of outputs, so you could hear the difference between the two quite easily. When I heard it at my dealer's, there were some discs where I preferred the tubed output, some with the solid state output, but overall the solid state output seemed a bit cleaner. Who knows what would happen if you changed the tubes, though...
Does anybody have any thoughts on tubed CDP's in terms of pairing with a tube amp or tube integrated and getting too much of a good thing???
Another question... Would the addition of a tube buffer like Musical Fidelity's X10 or a tube preamp benefit a SS CD Player given the desired objective?

Thanks.
For Jh2os--there is never too much of a good thing when it comes to tubes!!! :^) I use an Audio Logic DAC, a Jadis JP200 preamp and a pair of Lamm ML 1.1s with no problems, but I do note that the better tubed units and solid state units are sounding far closer to each other these days than they did 15 years ago. I imagine if you get some heavily colored tubed components they may overdo it in terms of fidelity to the signal, but on the other hand you still might like what you're hearing enough not to care.

Mdp0430: Probably yes to some extent with the preamp, particularly if you've got a good CDP. With something like the MF X10, depends on your objective, in my opinion. With the MF you're adding more circuitry into the signal path, and essentially coloring the sound. In that case, if your objective is fidelity to what's on the CD, unlikely unless you really have a poor solid state CDP. But if your objective is to tailor a sound from CD that you can enjoy musically (and I know a lot of people who have a hard time doing that), and the MF does that for you, then that's probably the ticket.
I agree with Rcprince's response as well, Jh2os. We have a tube CDP running direct to tube amps, and absolutely love the sound.
