preamp vs. no-preamp

I have talked a lot about this subject in other threads. The inherent problem is that whatever parts ANY CDP is using to control its output/volume is not as good as a the parts in world class preamp that does the same thing.

It's like asking the question as to why should one go with a seperate preamp and amp when an integrated amp does the same thing. Yes I will admit their are world class integrated amps... HOWEVER, a well matched world class amp and preamp will beat a world class integrated amp any day of the week sonically. In this case though, a lot of the reason amp/preamp combo beats integrateds occurs because of isolation issues between low level signals and high level signals.

The problem is that too many CDPs that control volume use a kind of passive preamplification to do this. Basically most of them put out ungodly high outputs at full throttle/volume, and this signal is run through some passive preamplification (usually a type of metal filament technology) that contol it by the .5 db. I used to have a Camelot Uther DAC/digital preamp, and my sound dramatically improved when I moved to an active SF3SE preamp and having the Uther at max output.

My experiences are exactly oppostie of Keith's, I have tried a few pre amps and always found running direct to be better. I in fact did use a CJ Art series I and compared it running direct and both I and the other audiophile listening agreed the CJ colored the sound and lost a LOT of detail/resolution not to mention having a MUCH higher noise floor. I have tried a BAT VK-30se and found there was NO comparison between the two, the passive attenuation of the Capitole was leaps and bounds better. Other pre-amps that friends have tried include- BAT VK-50se, Aesthetix IO signature with dual power supply, Manley Steelhead, Lamm L1 and L2, Edge it just doesn't seem to matter most prefer it run direct. For that matter the best digital playback I have heard ALWAYS uses a passive attenuation of some sort be it in the CD player or an external along the lines of the placette. Any other thoughts on this subject? this really seems unusual that Keith and I would have exact opposite point of views. My only concern that I have right now is I would like more body/weight in my vocals and a slightly larger sound stage- would an active pre help this??? I doubt it- more room treatment, power cords or maybe a new amp is on my docket.

Tireguy, I am not going to claim I am always right. And I have not heard your CDP though I have heard AMAZING things about it. And if you have tried all of those preamps, all I can say is WOWSERS! I wish I were so lucky!

Maybe you have a magical kind of synergy between your CDP and your amp? I am not familiar with either piece.

If you want more body weight and a larger soundstage here is what I suggest getting: Virtual Dynamics Nite AC cord and Nite ICs. The combination is pretty frightening... The only thing I have to say about the Nite AC cord is it just is not fair that AC cords can make as big of a difference as it does in any given system. Especially when put on the Amp and Digital Source. It just is not fair.... The IC's are very good... They may not be absolutely neutral (my verdict is still out on them), but they initially impress me a whole heck of a lot.
