What combo for Rega Planar 3

Ok so a house move means we are going to have a shuffle around and so will have things set out differently

Currently have a Rega Planar 3 with the Ely's 2 cart, Marantz KI Pearl Lite Amp and the Diamond Speakers.

Now the setup is nice, but will need a slimmer amp with the move and unit that has been purchased. The Planar 3 will stay but looking for a nice smaller form integrated amp, the speakers will be going too. So looking to start to build a more long term setup.

Recently heard a Rega Brio and the sound difference compared to my amp was more open etc.

Thanks
