Running CD-Player Directly from Amp

I've had excellent results running the XA7ES direct. The Sony's remote adjusts volume remarkably well when run direct. The XA7ES is every bit as good as the 830, IMHO of course. Enjoy!

Resolution Audio CD-50 and CD-55 players both have variable analog outputs (balanced and unbalanced), and both are available used for less than $2k. I run a CD-55 directly into my Bryston power amp with excellent results.

I have a Theta Miles (balanced version = $1400 used) that has an analog volume control and drives my BAT VK-500 really well. Impedance between the two components seem to be no problem. It is definately better than when running through my Forte Model 2 preamp. Part of the problem may be that the Forte has only RCA outputs and the BAT XLR inputs. I convert with a AQ Lapis 3 RCA to XLR IC. I don't know how much this conversion process degrades the signal.

I think the general consensus about driving amps without a preamp is that it provides more detail and clarity. Many people seem to prefer good preamps in their systems because they provide more bloom, dynamics and overall magic to the sound. I'm sure a big part of this depends on the efficiency of your speakers, the gain of your amp and the output of the cd player or DAC.

I would definately give the Theta Miles CDP a listen in your system.

Here is a slight twist, have you thought abut using an amplifier with a volume control? I am using a David Berning ZH-270 amp with an Electrocompaniet EMC-1 cdp and I am getting very good dynamics, detail, and resolution (overall, better purity). My speaker is fairly efficient at 91 db/8 ohms (very linear).

I agree with Drewfidelity that there are many variables when you introduce another component, such as a pre-amp. I don't really believe there are any components that are totally neutral so, the introduction of a pre-amp could be either pleasing or disturbing to your taste. Certainly, a good pre-amp can provide more drive and dynamics (especially when using long interconnects). Some use a pre-amp to add a certain flavor that are pleasing to their taste. As they say, different strokes for different folks!

I think it would be a tremendous advantage to audition equipment in your system to determine your personal preference.

Thanks for the thoughtful responses. I learned a bit more from searching prior threads. To be more specific with my quandary, I have a very nice pair of Linn Sara 9 speakers that work well in my room (close to wall, further from big dogs...). I am currently using a YBA Integre int. amp with Rega Planet CD. Although I like the sound of the CDP, I'm afraid the Integre doesn't have enough oumph for the fairly inefficient (isobarik) speakers. I've been considering getting a more powerful integrated amp, but thought I might look into an amp/CDP direct pairing to give me a bit more bang for my buck.

I've put the Theta Miles and Resolution Audio 50/55 on my short list, but perhaps there's an integrated amp that would work well with my Rega Planet? I am partial to the "musical" (i.e. British) sound.

Actually, another thread might be in order...
