I own an LSA Statement and it is by far the best amp I've ever owned. While I haven't had too many big $$ amps, this was the first one that gave me everything - staging, tone, PRAT, and by far the best "impact." It is one of the few things I've found that drive my ProAc's to their potential
I think there are a lot of similarities to the designs (dual mono, big Toroidal transformers, etc). The LSA uses a tubed stage which lets you customize the sound a little with tube rolling. In the end, you can only try them out.
(full disclosure, I'm currently trying to sell my LSA Statement - as well as the rest of my primary system - for purely financial reasons. Job change and a move coming).
