In a word, no.
The original standard for LCR equalization is a passive module that goes between a high-gain linear amplifier and the rest of the system. Because of the way inductors are made and perform, it is not practical to operate them at high impedances, and the standard modules are all designed to operate at 600 ohms. Hence a studio mic preamp could easily be used since it is designed to drive a 600 ohm impedance, and it has very high gain, 60dB or more. The LCR module attenuates the midrange by 20dB, so high gain is needed in front of the module.
Eros, Seduction, and most phono preamps operate internally at much higher impedances, 10 to 1000 times higher. To get these low impedances with tubes usually requires a step-down transformer to drive the LCR module. Sometimes a modern LCR phono preamp will have lower gain before the module, and another gain stage after.
I think all this came about as electrical phonographs were first becoming available; there were no dedicated phono preamps in radio studios, but plenty of mic preamps and the usual gain controls, source selectors, etc.
It's an attractive purist approach to phono reproduction, and I'd love to explore it further. But because of the step-down transformer, it would require a third gain stage as well as the output transformers, and would necessarily be expensive. The configuration is basically similar to our high-end Tape Repro amps.
