Off on a tangent. I have the XA25 as well and did have the XA30.5. Pass Labs also believes that power cords also do not make a difference. They do not make as big of difference as with some other equipment, but I have found a quality cord like Audience or Audioquest can even improve these wonderful amps.
I am reading this thread because I plan to try the Oreas under the Pass Labs soon:)
