I certainly was not expecting such a big improvement, especially the blacker background with more detail and resolution. Additionally, PRAT is better. The preamp is really fast. The Pass seems laid back in comparison. The weaker bass may be an issue for me in the long run. This morning the sound stage is starting to open up slightly after I let the tubes burn in for an additional 3 hours.

The BAT certainly resolves the issue of the midrange being a little dry and sterile as reviews of the Pass X250 have stated.
Sounds like a winner and I'd love to hear it.
