ARC DSI200 or Bryston 4bsst2 & ARC SP16L

Currently own a Bryston 4bsst2 amp. I'm about to try a ARC SP16L as the preamp, but I'm also loving the look of the DSI200 by ARC. I'm considering selling the Bryston amp to finance the DSi200. I'm trying to get a little more warmth from my system due to a recent speaker change that can benefit from some added warmth. Comments appreciated. : )
I don't think the SP16L will add much warmth IMO. You might want to spend a little more and look at something a CAT or Joule, VAC or Hovland. More detail and less coolness.

Nice room by the way.
