what amp under a grand?

ill check them out.changing speaker placement did clean up the sound though.

mccormack dna 1 or 125?

It may not be your amp, but if it is, then ditto on the McCormack. I'd vote for the 125. The "McCormack sound" may not have the very last word in HF extension or air, but their amps are very highly regarded in every other respect. 125 should be slightly more transparent and neutral than the DNA 1, if both are stock.

McCormack dna 125 or rotel rb 1582?

Your speaker is very musical and could certainly be described as a tad dark sounding. A higher power class D amp would be the best choice. It will balance out the speaker perfectly and for little money. You can buy brand new monos from Ghent Audio for $999 with a trial period.

You can find used Bel Canto, Nuforce etc amps that would also work wonderfully.

I use a Bel Canto Class D amp with mine and the combo is perfect.

Your speaker can certainly sound a tad dark and muddy with the wrong amp. You want a crisp, clean, fast and neutral amp for your speakers. You want power and your speakers react well to lots of power. Class D is not always the best choice, but in your case they would be ideal.
