unico with nht 2.5i's

well, i picked up a Unison Research Unico to try out at home. Associated equipment...Rotel RCD 971 w/ MSB Nelson link III, NHT 2.5i speakers...

First impressions...

Open, very wide, quite detailed (but not hyper-detailed like some others)

Quite good imaging...sometimes it seems a bit 'phasey' (certain details seem to come from 'odd' placement points - not sure if it's a funtion of the recordings that I just didn't notice with my previous equipment)...

Biggest concern - Bass. Seems to be a bit sloppy, or rather, it's a bit slower than the mids and highs. I suspect that it's a combination of my speakers being ported and the tube preamp section of the integrated. I've heard that using the Unico with ported speakers may produce this type of result... I imagine it would be much better with regard to bass using sealed speakers.

I don't think I'm going to keep this unit. I realize that it is in a 'higher league' than the rest of my equipment, but because I cannot afford to switch all my associated gear, I think that I'll have to find something more in line with what I currently own.

Any comments? thoughts? thanks
