While we can't speak a whole lot to the performance of the Jolida, I do see six opamps in there, so I would wonder what contribution the tubes are making.
The Eros will work with a LOMC, but you'll want to get some appropriate step-up transformers. We have included mounting holes in the chassis for 3/8" bushing mount step-up transformers (Sowter and Electra-Print tend to use this package), but holes could also be added for mounting Jensen or Cinemag step-ups that use the two sheet metal screws.
The Dynavector SUP-200 would be another option, but the price is somewhat unreasonable.
