NAD 320BEE with PSB Floorstanders

I have a NAD 320BEE paired with PSB Image 2B. I'd like to move to the floor model PSB, either T55's or the Silver i's. Is the NAD powerful enough for these speakers? Are the Silver i's overkill. I only want to change one component at a time and I tend to like the NAD amps and the PSB speakers, so I want to stay with these brands. Thanks for any help.

you will be fine...the nad is refined and has enough headroom to be dynamic with pretty much all psb's
