Snooker,
I really like the Ayon family sound and the Spheris is the preamp in my dream system (the amp is the Ayon Titan mono blocks). Still, auditioning the Spheris with your Pass x350.8 amps would certainly seem prudent.
I read the specifications for the Spheris and it listed an output impedance of 30 Ohms. The single ended/balanced impedance of the X350.8 was given as 50/100 kOhms. From what I've read related to rules of thumb for preamp/amp matching, it seems like that should be a good ratio, but I would defer to more learned members of this forum, or better yet I would call Pass Labs to discuss.
On another note, should you ever decide to move from the CD-5 to a media player, I highly recommend the Ayon S-5.
