Received my MB-2.5s last Friday. The speakers were literally brand new as the dealer said. Then of course they sound brand new, too. My first impression: Large, deep sound stage with pretty decent treble and mid. The bass is boomy as everybody said when these speakers are new and not broken-in yet. I only have a few hours on these speakers so I still have a long way to go. They do need to be separated far. I placed them 9 feet apart as Xti16 suggested and the sound stage is quite impressive.
