Couldnt agree more with the Audio Refinement Complete. However, since you mention a Rega P3 as part of your system, as far as I know, the Complete does not have a phono stage (or am I mistaken guys?).
A good match with your Sonus loudspeakers would be Unison Unico (hybrid integrated sporting 2 ECC82) that has an internally switchable MM/MC phono input. You might find one if you could spend an additional $100 or so. Otherwise, there is the less powerful Unison Unico P (also hybrid with 1 ECC82, 50 Wpc/8 Ohm against 80 Wpc for the Unico), whereby the plain Unico is undoubtedly superior to the "P".
Good luck!
