Power/Current: How much is realistic?

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.

Any updates on the Coda’s with your 13A’s?
what Pre?

Just waiting for the new Coda 07x Pre to come in.  Doug is making a new run now, Pretty busy after that review. Stay in touch.

Hey Millercarb, Whats wrong with Martin Logan ?
Just curious to your post
Mike

Why? Is there something wrong with them?

The comment was as usual provocative, specifically to provoke thought. You said,

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.

So you start with "rebuilding my system" and end with "without spending a fortune on something I do not need." But then you went and bought ML. Why? If you didn't know it then, I sure hope you do by now, because just look at the can of worms you opened with that one choice. Pages and pages of mind-numbing technical mumbo-jumbo and why? ML.

When there are all kinds of great efficient easy to drive speakers. And note, NOT saying anything bad about ML per se. People have a hard time with this. So I'll say it again. Because I know they have their fans. Not saying anything bad about ML. Heck the first speakers I built were ESL. But that was how I learned a lot of the crap above. Its not that there is anything "wrong" with them. Its just that they limit and greatly compound your amp choices. Which is kind of inconsistent with not "spending a fortune on something I do not need." You created the need when you bought the speakers.

That is all.
