I’m in a similar situation, although I do not know my room size yet as we will be buying a new home in the spring and I plan on having a dedicated music listening room with two channel. With that it may be possible to be a 10’ x 12’ bedroom or larger den/family room depending on the house we find. But, I am seriously considering a pair of Buchardt active speakers with just a pre-amp with balanced outputs driving them. That way I can spend more on the speakers, pre- and front end without the huge cost and weight of a power amp. Backert line stages look perfect for the bill, although I may consider (possibly used) Jeff Rowland or Audio Research. With the Backert i would need a phono pre, but many affordable ones are out there.
