I recently asked myself the same question and did a fair amount of research and experimentation. Many passive devices will reduce dynamics. Sound quality is also a function of the CD player output. AudioNote has tones of gain, so most passive devices work well. So it is important to listen to the options.
Stan Warren has a schematic for a new buffered line stage. If you send him a SASE he will send you the schematic and 1 day later you have a preamp. Placette is one option. Gilbert at Blue Cirlce will make his BC3 preamp for you with a single imput. Portal Audio will be introducing a remote controled volume control in the near future. Ray Samuels at Ray Samuels Audio has a simple 2 input unit. So, yes, there are options, but you need to take the time to listen and be sure that it will mate with your system. Get a used McCormack and have Steve update and modify it to single input at the same time.
Hope this helps.
