Which would you choose?

Hello all. I am putting together a second system based upon vintage components. These include a Sony SCD-1 CD/SACD player, a Threshold 3.9/SE power amplifier, and a pair of Alon Phalanx loudspeakers. All cabling is generic, being a combination of Beldin and Canare.

I have narrowed my preamp choices to the following: a Krell KRC-HR or a Pass Labs X-02.

Thus my question, which would you choose?

Many Thanks!
