Hi,


I am trying to build a two-channel system for music from CDs. As far as I can tell, the only thing a preamp does in this case is act as a volume control--I do not need all the fancy surround processing stuff nor a phono preamp. In this case, is it really worth dropping $1K on an active preamp? Can I get away with using a passive preamp and spending my money on a quality amplifier?


Another option: what are some CD players

My system right now consists only of a pair of Paradigm Studio 100v2's.



Thanks!

You could build your own passive amp... there are several high quality attenuators that are available.


Or you could buy a high quality pre-amp, say a Audiolab 8000Q.


Plugging a CD player directly into a poweramp is not recommend. Some default to 100% on power-on (CD.P) be quite nasty if you forget

The best would be the CD player with a variable output, HOWEVER, try to look for a quality CD player that attenuates in the ANALOG domain. Those that do it in the digital domain do so at the expense of resolution (truncating bits - unless someone's devised a better way to do that). I really haven't looked at CD players with variable outputs lately, so I really can't give you any leads to start on.


As for a passive preamp, I'd have to recommend the TLC-1 by McCormack (probably REALLY cheap used now) - it was the unit way back when that got me started on this high end thing. One thing if you go passive - component matching becomes very critical: you'll need to make sure the output voltage of your CD player is sufficient to drive the amplifier, since there's no gain factor thru the passive pre. Some people also say you'll lose dynamic range when using a passive - I didn't really notice that more so than the transparency and smoothness I got taking out an active component in the chain - well worth the tradeoff!


Good luck!

I have the Accuphase DP-70 CDP as well as the Yamaha CDX-1050 which both adjust the volume in analog domain and I use them connected directly to my power smps with really good results but mind you there will be no tone controls not that you need them with good speakers.

sanction,


I am currently contemplating the same thing you are and, I think if matched correctly, a passive system would serve just as well or perhaps even better than an active system (signal from your CD player doesn't have to pass through additional A/D-D/A conversions and gain stages) while, as you have surmised, allow you to allocate a bigger portion of the budget toward a better CD player or amp.


At the ~$1000 budget you have set, I would look at getting a combo like the Music Hall CD25 CD player (retails at $600 but can be had for less if you negotiate and as low as $400 used on audiogon.com) and FT Audio's LW1 passive preamp ($500). Both have gotten great reviews and are considered great values in audio.


Though more expensive, other CD players in the same class you might look at include the Arcam CD-73T ($700) and the Rotel RCD-1072 ($700). Put together a system with a great stereo amp like the Odyssey Stratos ($1100) and I think you've got a system you should be very happy with.


Here are some links about some of the products I mentioned. Of course what you go with will depend on you auditioning them and seeing what you like.
