The Spark is rather a lean speaker to begin with. Maybe you should look at a sub woofer.
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?
