BAT SS amps VS Ayre MX-R

I have a BAT VK-250SE with a VK-52SE preamp. I'd like to try a different solid state amp and eventually preamp to go with my Hansen Audio Prince speakers. I think the Prince's would benefit from a more high powered amp. I like the overall sound of the BAT equipment. I've considered the VK-600SE. I'm just alway interested in something different and maybe better. I'd like to hear form anyone with experience with either BAT or the Ayre MX-R amp or any other suggestions. With the Prince speakers I've left the upgrade path. I'm looking to do the same with my electronics. My front end is a Modwright Truth Transporter with Vintage tubes. I'm very happy with it.
