cdp digital volume control or preamp?

This seems like deja vu....this seems like deja vu...
Lots of opinions on both sides of this coin, search old threads. The only way to know for sure for your tastes and in your system is to try it both ways. Some seem to believe that a preamp may improve body or dynamics. Then you add passive preamps to the equation...

If you search 'passive' here at a-gon (classified not chat) you will find a couple of passive preamps so cheap they might be fun to play with, the Channel Islands and the Luminous Axiom. Just a thought. By the way Lousyreeds, tfkaudio mentioned that his volume control was digital but his question was not specifically about the pros and cons of digital volume controls but also whether to add a preamp. The thread seemed to morph in that direction. Thanks for being there to correct me anyway.
