IS THE MARTIN LOGAN Renassance 15A worth the $10,000 higher cost than the Expression 13A

i have the 13a's .. love them...15a 's provide more of the same sound...the signature sound holds true from the 11a to 15a imho.

my room is 17 by 16 and they work nicely... 

these speakers are very revealing.. they will demand good clean electronics and wires upstream for sure.

i like to use solid state amps with tubed preamp.. i use krell/arc combo with mit wires
