Power/Current: How much is realistic?


Rebuilding my system, Just got a pair Martin Logan 13A, B212. Just looking for insight on how much power/ current
would be enough without going overboard and throwing $$ away. I know i am only driving the panels. Had a Krell fpb-300, 400cx, 350mcx driving M/L Oddessy Descent i. Should i go up to 600watt?  Looking for that last amp without spending a fortune on something i do not need. Thanks, Mike

A big Thanks to all who posted I just pulled the trigger on a pr. of Coda Tm monos. Will let you all know how they sound with my  M/L 13a's.
 Another shout out to tom6897 Thankx
Congrats, those should work very well.
I have just recently received a 7X pre and a 15.5 amplifier from Coda replacing my .8 Pass Equipment and could not be more pleased.
As much as u can afford, more is always better.
 Had low power, mid and high power, high power amps are always better at crescendos, power chords, maintaining the current.
