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?

A great more pwerful amp isn't always the end to all ends.So much of what comes out out of the speaker;isn't "all" about the amp.Good front end stuff/ cabeling/power conditioning/power cords/--Componant Isolation/ and room treatment/All have just as much to "say" about the music coming out of the speaker,as the amp driving the speaker.
Difficult to answer simply. A bigger amp will not necessarily add more warmth. The marketing of more and more "power" as watts is misleading. A bigger amp, IF WELL DESIGNED will sound more "warm" at lower levels because it will probably be able to push more current when the music requires it, transient response. This is a major reason a larger amp is needed and its often a matter of current, not watts. A solid state amp will clip and send a square wave through the system and this sounds rough. One reason a tube amp sounds warmer is that do to its design it does not clip in htis fashion when it is momentarily pushed to its limits. Other that this power does not translate directly or easily to sonic differences.

As you noted tubes are great for warmth and many of the SET amps have no more than a few watts.(of course they use effecient speakers too)

Don't buy into the power thing. Not that it cannot be a factor but it is more a matter of design. Quite frankly, the way wattage is advertised I think it is mostly a macho marketing devise more than anything else. If you like to read about this stuff there is a great article on SS power amplifier supply on the Chicago Audio Society's web page. I do not have the page handy but just do a search on that name to get it.

Also, have you done eveything you can as far as speaker placement?
Good luck listening.
I understand that obviously all of the components affect the sound of the system. I am going to experiment with some tweaks, then if I'm still not happy, the front end. I guess I
have misstated my question here. Aside from the other problems, I guess I am looking for a more dynamic, balanced sound at low volume; the kind of sound I get when I turn it up. I am wondering if, in general, a more powerful amp will provide this, or should I look to upgrade some other component. Thanks for your help.
