@OP, I like the rec by Mr. Bourne above. How possible is it for you to keep two systems or have options open so you can go back and forth? That may be something you aren't interested though.
CHANGING FROM AUDIO RESEARCH TO AUDIO NOTE SYSTEM
Dear All,
I got hooked by the SET sound and am considering selling my Audio Research based system (REF 5 SE preamp and REF150 power) and Wilson SOPHIA 3 speakers. In exchange I would buy a level 3/4 system. M3 phono balanced input pre, P3 Tonnmeister power and AN E AN-E-SPe HE 98db or AN-E/SPx ALNICO 95 dB speakers.
However, considering the good quality I already have, I fear being a little downgraded. Wonder what is your opinion.
My room allows corner placement, and has 30 m2 with 2,4 m height ceiling.
Best regards,
