ICE amps vs analog amps for bass

I'm currently running Legacy Helix loudspeakers. The bass and subwoofers are being driven by two pair of 500 watt ICE amplifier modules while the Midrange and treble frequencies are being driven by two pair of Levinson 436 amplifiers. While originally auditioning the speakers I heard them with analog amps on the bass, treble, and midrange sections and the sound was superb. However, I was assured that the ICE amps would be sufficient to drive the bass sections so I've given them a try. However the bass sounds funny. I don't hear the impact, definition, and subtle "spatial cues" that I know are in the recordings.
I partially am blaming the ICE modules. I'd sure like some input in solving the problem. I can "upgrade" to "analog" amps for the bass if I choose, but for space reasons and economic reasons, would prefer to continue to use the ICE amps. I'm considering Parasound JC-1s, or Bryston 7bs, for the bass if I switch.
Thanks for your help in advance.

Thanks and when writing before i think you were referring more to the high damping of the ice amps if i'm correct.Also am i correct in that a lot of people think they can get more out of the recording then there really is on it in the first place?

Hi Coffeey,
Thanks the info I'm not hearing is on the recording as I've heard it on my previous system and others. I know the Helix should be able to provide this definition also. I heard it at Legacy headquarters, but have not been able to find these missins notes at home. That is why I'm questioning the ICE amps built into the speakers and am considering switching out the ICE amps for the midbass and using a more normal amplifier design like the Bryston or Parasound.
Thanks,
Steve

Just to clarify, have you hard other amps at home with your speakers that you liked better? Or are you basing this from hearing the speakers at another location in another system?

If the latter is the case, room/setup will make 1000% more difference than amps IMHO, assuming no major electrical mismatches
