High end stereo preamp vs mc preamp?

So thinking about spending $10-15k for a quality stereo preamp for bypass use with ht system. Have a middle of the road avr, which is now used as a preamp, which sounds fine for ht.

now wondering if a hi end ht preamp, 5 to 7 channels, exists that achieves a level of quality offered by a high end stereo preamp. Seems same level of spending toward a stereo preamp must provide opportunity to get an amazing ht preamp with a great stereo capability
