Replaced my entire system within the last year. Previously had an original Linn LP-12 with Sumiko arm and Benz Micro Glider, Audio Research PH3-SE, Audible Illusions Modulus 3, McCormack DNA-1, Rega Planet, MIT interconnects, Magnepan 3.3's, fully reconditioned at the factory and an NAD 4020 tuner.
Finally went the tube route and updated the table and speakers. Much more musical and open. The Einstein seems a much better match since it has 68 db gain compared to the ARC PH3SE with only 54 db.
Very happy at this point. May look at other cartridges, a balanced phono section, and a tubed tuner down the road, but...
Great system. Looks very thought out. Your room seams to have a cool vibe to. Enjoy the great tunes. And the those 3.7. Trust me you have some of e best speakers in the world. Once they break in your gunna freak with joy.
