Do you think it is worth it to move from a NAD 2400 to a HCA 1000? Will be used to drive my 1Cs.

I have a hca 1000a on the way. Will let you know my impressions

For what it's worth I switched out my NAD 2150 for my Parasound HCA-750A and noticed a VERY distinct difference. The 750A produced a less harsh sound, more blended sound stage, and warmer sound. I was more than a bit surprised. I'm using a NAD 1020 pre and Polk Monitor 5.
