Levinson 383 integrated vs Moon i-7 integrated

have heard the Concentra (not the Concerto) and while it has beautiful tone, unmatched in my experience in SS integrateds, was a little thick in the upper bass and not especially extended or open up top.

I know that Jeff Rowland integrated's are designed differently than most. Rowland is able to get more power out without the units weighing tons. I have a customer that manufactures 200w amps for announcement systems...their units weigh very little.
I do know that I've always read great reviews on the Rowland gear. I'd like to take a listen first before I make a choice. Sally

Krell 400xi is the bargain of the century plus a world class integrated. Soon to be discontinued, I would suck one up now!!
