usually, if the input impedance of the next stage/piece of gear is 10X the output impedance of the previous stage/piece of gear, it is sufficient. So, if the CJ amp has about 20K Ohms input impedance, it *should* be OK in that it should not load down the preamp o/p stage.
The reason for the lifeless sound for the FS-CJ combination could have been something else besides impedance mismatch.
Eps, your orig post has no text supporting an impedance mis-match - you merely state that it's likely a mismatch issue. How did you conclude it was an impedance mis-match?
