Sometimes I wish I'd grabbed an early pair of 2.7s that were available to me, if only because they are a bit smaller and they had the ebony finish I coveted.
Still, it's simply astonishing how well the 3.7s work in my small room. In terms of "room problems," frequency bulges or nodes they are as perfect as I've ever heard in any speaker anywhere. There is literally nothing in any track I can play that trips them up and calls attention to the speaker.
And, again, that's driving them with the CJ tubes. Though I used to own a smaller CJ tube amp many years ago before the Premier 12s, and it didn't control the bass of larger speakers like the Premier 12s do.
As I may have mentioned earlier in the thread, I've also sometimes hooked up my tiny Eico HF 81 14Wpc integrated tube amp and, aside from the bass getting a bit overwarm, it sounded glorious with the 3.7s.
