Ice amp's may show good numbers when it comes to watts but they are very low current , many speakers require current to bring them to life .
I tried a friends Bel Canto Ref1000m's with a power rating of 500w at 8ohm and 1kw at 4 ohm , they produced much lower volume levels than my 200w at 8 ohm A/B designed Levinson amp . The lack of control was also very apparent on my mid efficient ( 87db ) Salon's .
That being said I would still try a friends preamp in your system before giving up on your present power amp .
