I'd think the 140 should match Ref 1 quite well. I can only speak for (my then) D-Premier and Kef Q300 which was an excellent combination. I believe the Ref 1 is similar, but clearly superior to the Q300. If you find that you need more power there is the nice possibility to upgrade to a dual-mono 210 amplifier.
EDIT: In addition Ref 1 is in the SAM data base - profiles for both the short and long ports so that would be very good.
