Bigger Amp?


I am considering an amp upgrade and would appreciate some (friendly) advice. I am currently using a McCormack DNA-125 to power a pair of Audio Physic Spark III's and although I really like the McCormack, I am looking to add a little more warmth and presence to my system. I have heard some say that a more powerful amp will add more presence, even at low volume. I prefer to stay with SS since I can't afford to buy/maintain a good tube amp. Can any of you big SS amp owners attest to what more power will get me (if anything) at low volume?

My system is:
Theta Miles (Balanced but using SE)
HT Pro Silway II
DNA-125
AP Oval 9
Spark III
Absolute PC's
PowerWedge 114

I've spent a lot of time on speaker placement and tried a couple of other amps (Classe, Bryston) but preferred the McCormack, even though it doesn't have the balanced inputs.
Craigklomparens, I agree, the ability to deliver an abritrary amount of current instantaneously is probably the biggest factor, and as you stated this may or may not be true with a "more powerful" amp. I guess this is what we call a "faster" amp? It looks like you have answered my question... thanks again.
The Spark is rather a lean speaker to begin with. Maybe you should look at a sub woofer.
as far as ss amps the amp you have is about as warm as ss gets. conrad johnson owns them now.[ great company] as far as tube mantinence, they are not hard to keep running if well built. if a ss amp wears out its outputs thats not cheap. if a tube amp wears out tubes just pop in some new tubes. most tubes will last a long time though. just buy a good tube amp and never look back. i am sure you can trade that ss in on one, are someone might do some trading with you. i might even take it towards some tubes i have.
A second thought on the never ending shuffle of equipment. You say you don't want tubes but me thinks its going to haunt you. You sound like me a few years back! (no insult intended and I apologize in advance.) I have found that the best soft dynamics I have ever heard have always been with well designed horn speakers. Oh Oh,- there goes the whole system! There is a discussion about this at audioasylum.com in the effecient speaker forum (dated 12-15-01) called "Higher effeciency=Better dynamic impact?". I think I agree with the general drift of the discussion there. Check it out and keep listening to some good high effecient horn speakers with tubes. God Damn the Pusher!

The HT Pro Silways introduced too much shrillness/brightness/sibilance into my system. The Truthlinks were a lot warmer sounding at the expense of some rolled off highs, but worth it to me. I currently use something else, but possibly you could experiment with some different cables before changing gear.
