The old Sonic Frontiers Pre-amps might work, although you might not find them "tubey" enough for your taste. Upscale Audio in Upland, Ca has a top of range Line 3 (probably the one I traded in there last year) listed for $2500 on their web site. It is a terrific sounding 2 chassis pre with all of the features you seek. I traded it because a) it needed some minor repair/maintenance and b) my new listening room made locating the 2nd chassis a pain in the ass. I'm sure that Upscale has seen to the repair and maintenance issues.
Good Luck
