Yes, you'll need to at least double your power to get dynamic improvement. Bear in mind that doubling your power is actually only a 3 dB increase in volume.

Despite recommending the ClassDAudio amp, I also tend to agree with those who recommend Adcom separates. As Blackraven and maybe others have mentioned, the Adcom GFA 555 or better yet the 555II are great amps for the money.
