I've owned the SF Cremona Auditor M's for nearly 2 months and use them with a REL B2. I am using a Levinson 38S and 334 and 390S and the combination is stunningly detailed and musical. I did not hear the SF's with Meridian gear, but everything I heard them with (including Ayre, Nagra, Accuphase, Luxman, Shindo, and of course Levinson) sounded great. There were some differences, of course, but they were mostly subtle (to my ears, anyway). I suspect the SF's will sound good with most quality electronics, but "Tweak 1" 's comment about checking with the manufacturers and hearing the setups in your listening room et al really is the bottom line.
Good luck! And welcome to the Sonus Faber / REL fan club! (Don't know that there actually is one, but there should be!)
