Quite happy with my Luxman CL38uc -it's at the top of your budget but you do see the odd one come up for sale. Tubes if you're that. I like the combo of a tube preamp and ss amp. If I've a complaint it's the lack luster remote for what that's worth. Otherwise no question regarding Luxman quality, both build and sound. Lots of "professional" reviews out there that are all positive.
