Sonic differences between Conrad Johnson preamps

I upgraded recently from a PV-5 to a PF-R and I was astounded at the difference. Some would say that the difference in transients is probably due to SS vs tubes, but if so, so be it. The speed of this unit is startling. I bought my PF-R for $925 from Ebay, which I would think would be a good starting point (dollarwise) for a second system.

The PF-2 is a very nice warm-sounding ss preamp, and a steal at the used prices I have seen. If you don't need a remote in your second system, you could spend half what a PFR would cost and get a very similar sound that is very easy to live with. If you use your second system sporadically, the PF-2 may be a good hassle-free choice. It is "on" all the time and always instantly ready to provide great music.

I used a PF-2 for several years and recently upgraded to a new c-j tubed preamp (PV-14L) that cost twice as much. I'm not really sure I prefer the sound of the new one and may just switch back to the PF-2.

"The CJ PFR solid state preamp is a close clone of the Motif MC-10. The Motif line did have many higher spec parts than the cloned CJ models."

Perhaps, but the PF-R has soft recovery diodes, meaning low level detail will not be lost by a muddy DC bias. I strongly suspect that the PR-R would spank the MC-10, though it does need Black Gate caps to be all that it can be.
