Another way to do it is to buy the best CD player, up to $750, used, without volume control, so that CD quality is not impaired by cheap volume control. Purchase used, or new ($350 list, from tweakaudio.com) EVS Ultimate Attenuators which attach directly into the RCA input jacks of your amplifier. For single source system, such as CD only, you may never have to buy a separate pre-amplifier, either passive, or active.
There is a model for transistor, or tube amplifier, and you can email Ric Schultz at tweakaudio.com to match your amp specs properly. Whatever your CDP, and amp are capable of producing can be optimally heard with this set-up.
