How Much Preamp Gain is Too Much?

In the age of the CD player, how much preamp gain is too much? Since a CD player has enough voltage to drive almost any power amp, why do I continue to see preamps with what would appear to be quite a bit of gain? While I do not prefer having a player with an integrated volume control, all that seems to be needed between a player and a power amp is a quality volume control (i.e. a passive preamp). I have heard that passive units tend to cause a lack in dynamics (in comparison to systems employing an active preamp). I cannot imagine that this would be true in all cases.

I have a Canary Audio CA-200 passive on the way. However, I also like the idea of putting tubes in front of my B&K Reference 200.2 power amp. I have the Quicksilver Line Stage (non-remote version) in mind. The Quicksilver seems like a nice piece. How will its gain affect my system? Since I listen at lower levels, I imagine I will be in the lower portion of the volume control (where a volume control tends to be less linear). I welcome any comments.

Thanks.

Sounds to me like you have it figured out and just want some reassurance.

You are correct on all fronts, no need for gain, almost all CD layers can drive an amp to full power, passives perform better or as well as actives when properly implemented, you don't want to be at the lower end of the volume control,

Check out the TVC passives that Jeffrey Jackson is selling, very nice and not too expensive.
