Hi Mikefi,
I've been playing around with various amps and preamps lately to drive my Avalon Opus (not the Ceramique version). I have been finding more of a difference between the various amplifiers than the various preamplifiers. I haven't tried the older X1 / X0.2 series, so I don't know the difference between them, but I have been listening to the XP-10 as a possible upgrade.
Still, the difference between the preamps has not been as great as the differences between the Pass X250.5 and the Pass XA100.5. So, from my experience anyway, it would make more sense to wait and do an amplifier upgrade instead of a preamp upgrade.
