This is a problem us multi table users face, in fact a bona bona fide dilemma! What to do...what to do...
One solution is multiple phono stages and transformers. I went this route fearing though the long interconnect runs to the main preamp (currently a Wyetech Opal). This actually worked out well, the Wyetech has four or five line inputs so I can switch tables click-click-click. I did not notice any sonic degradation with the longer runs and the versatility is fantastic.
I stand in front of the system like a conductor with his orchestra and select the different players... Mr. Brier or Mr. Koetsu, or Mr. Mark Levinson, or Mr. van den Hull, or Mr. Carr. It's marvelous.
