Try the Mod Squad Line Drive. It's called a passive preamp but it's really a quality-switching device. It gives all the versatility of a preamp but without the gain/color. They can be found on the used market for $100. to $150.
Do I really need a preamp?
I am considering another preamp to go with my CJ 2200. Am thinking about a CJ pre to go with it. However since my main source for listening is a cd player which has variable output, why do I need a good preamp. I have an Adcom GTP 450 tuner/preamp which will do the job for radio, tapes, etc. That said, how can I run cd and pre into the amp? As always, your help is appreciated.
