Jeff Rowland Concentra VS Krell KAV300i???????

I wouldn't match Rowland with SF. Krell's a better match. In fact, Franco uses Krell monos...

Warren,

SFs can use a more aggressive sounding amp in my experience. The Krell 400i is probably a better bet true.

I still don't think the more laid back Concentra is a good match (and i owned one, so not prejudiced towards JRDG)
