Your volume level should be adjusted to match the volume level of the other source components you are using so that when you switch between sources they are all at approximately the same level. IF you do not have other high level sources - forgo the preamp. As a general rule of thumb, you should set the volume on the CD50 towards the high side or all the way up. The CD50 has a LED bar showing levels, the CD55 has a numeric display.
Have you tried running the CD50 without a preamp? It sounds the best this way. The Resolutions have an excellent volume control - it works in the analog domain and does not degrade the sound (unlike the volume controls on Wadia players which sound better using a preamp). With the Resolution, the best preamp is no preamp.
