Integrated amp advice needed...

Hi Guys, considering new integrated. Here's my list of suspects, the new Musical Fidelity A5, Krell KAV 400xi., Bel Canto EVO II and new Bryston B100SST. I'm aware the the Bryston and Musical Fidelity are very new and not hot topics yet. I just want to get some info while doing my research and listening. I currently have a Marantz DV9500 and Mirage OM5 ( up for sale) too big for my new smaller digs. I'd like to latch onto the Gallo Reference III's or Thiel 1.6's. As always, input appreciated.
