I'll keep this going and throw in one more factor for powering the L300, is the listening room live/dead/neutral? With wall to wall carpeting on a cement slab and heavy drapes over the windows my listening room falls on the dead side. My listening levels are kept at a moderate level, with my large ss amp the sound is very full and accurate. On the other hand my brothers listening room is almost as large but very live and he requires a lot less volume from his ss amp to power his JBLs. I auditioned a pair of L300 in a live listening room powered by a tube amp, the mids/highs were very good but it lacked the solid bass/punch the L300 is capable of. My listening preference is mainly classic rock from the 70s and 80s and for my tastes the L300 is excellent.
