I am not sure you know the dealer.
I’m almost positive I’m right about the dealer…in fact, I would wager the cost of an in home demo that I’m right LOL! I hope you like the Grimm.
I don’t think we’ve seen any dealers whining…your points may be valid…or not, depending on the dealer’s goals.
If it’s the dealer I’m thinking of, this person enjoyed a very successful career, retired and started his audio shop. He carries some super high end gear and imports certain other high end, well regarded gear. I’m so very sorry the OP and this dealer found themselves with opposing goals because the OP seems like an outstanding individual and i know, first hand, that the dealer is. This dealer is indifferent IMO as to whether he sells a box or not. He would probably be the first to tell you that he doesn’t sell boxes. You say adapt or die? That doesn’t apply to this dealer I assure you. I would say that he curates systems rather than selling gear.
All’s well that end’s well and the OP was able to accomplish his goals.
