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.

hi Steve
i have used the 14bsst on my dual Volt 12" and dual CSS 15" and will say if you are using for bass only,go wiyh a older pair of 7bst(98-01) only..the sst only improved on the mid,slightly,so save the money .
i have also recently purchased a ML (333) for my mid/hi
