Nice. I just purchased the X-250 and X-1 preamp and have a Sony SCD-777 ES. I have been playing around with power cables and found that the cheaper AZ tsunami power cord worked great on the Pass amp giving it a more relaxed sound with great details. I want to try the higher priced AZ Gargantua cord (said to have the same properties as the Tsunami) but have not gotten around to the audition yet.
