@mm1tt77 Currently I’ve got a Zesto Leto pre feeding a Krell Duo XD - combo would be well above your budget so not suggesting this path, wanted to give a sense of my personal tastes when it comes to house sound signature.
Exactly, this is the gap not usually covered when dealing with the desire of the OP all that well. While many of us can recommend a really good SS amp option, often times well outside of the budget of the requester. And, not wanting to spend $10-15k on a worthy SS class-A or amp myself. For literally HALF the money $, some good mono tube amps out there, with true three dimensional sound, scape, tone, totally engaging sound with mainstream tubes offered today.
The OP mentioned the AVA DVA M225s, Schiit Tyr, looking at the $3k range is a small pool of amps to jump up and down about. I’m intentionally excluding the Benchmark having been there with their quiet-spec gear, and feel it takes a little more $ to buy something truly engaging as a keeper musical amp(s). With the right tube preamp, maybe the Tyr mono amps, might generate some interest, but I’d still likely take a good used Coda if I had to go back to SS. If the OP could bring the budget up a little, there are amps out there to make those BMR speakers sing more. Recap, the OP stated the BMR speakers sounded "neutral". To me that statement can also mean "lacking body" to some. Get the right amp and they won't be overly neutral or lacking body. Those are nice speakers when paired with the right amp(s). There are better amps to be had out there for a modest increase in budget. I consider amps core to my system. OP, good-used might be another option too.
