Oldskoolboarder, most of the great tube amps out there are made in China. (including ASL) You should be able to get some great deals there. I haven't heard the Prima Luna but many reviewers who I respect love them. Kevin Scales from Upscale Audio in Ontario California thinks they're great.

Don't know the Sophia, but I like the name.

Hope you find a good one!
