Philip,
What's your main speakers by the way? For sources, would you be willing to fore-go CD players instead go for the DACs such as from Linn, Weiss, PS Audio, Berkeley, Ayre, DCS ....to name a few. I'm not as experienced as most seasoned audiophiles here, but I think these are some of the best digital sources available in the market.
I heard the Pass XP30 last year, for SS, I really like it and IMO this would compete with the very best out there including tube based ones in terms of transparency and straight wire concept (no coloration). But I would leave the preamp option last, instead try the DACs directly feeding the amps first as most comes with variable output and see if it matches well with your system. Most audiophiles experience thinness when fed directly. But depending on the I/O impedances b/w DAC and amps, type of speakers and ancillary equipments, one can be a rewarding experience.
Best,
