Looking back at the NR1200 unit vs PM6006+ND6006 and PM7000n (which I own already). Are there any indications that the NR1200 may struggle with low impedance speakers (i.e. KEF R's - 3.2 Ohm minimum)? Would there be a merit in moving onto the PM+ND combo? The NR1200 seems like it has a decent amp section, although the 4 Ohm rating is not provided.
What best price could you do the PM6006+ND6006 combo and PM7000n? I really like the PM7000n but I struggle to justify getting another one for a secondary system (unless you can do a great deal, open box, demo unit etc.)
