When I went digital, everything including the turntable was processed digitally. The only thing added since then (1995) was digital RIAA correction.
Living is learning and as you move along the audio evolutionary curve you learn about component interactions and problems you did not expect that require solutions.
My main speakers will be bi amped not tri amped. This allows me to get rid of the RC network between the two transformers and use an amp that will handle the very low impedance of ESLs at high frequencies. I know of no better amp to drive the midbass and midrange of ESLs than the Atma-Sphere MA 2s. They are capable of putting more power into ESLs at those frequencies than any other amp. The problem is they have an output impedance of 1.7 ohms and the ESLs drop well below that at high frequencies thus the high frequencies roll of after 12 kHz. It is a very popular combination usually only affordable by older gentlemen that have already lost their hearing above that frequency. Only solid state amps have the ultra low output impedances that will drive ESLs at high frequencies effectively, thus the odd combination.
You may have arrived at your destination. I am still enjoying the trip.
