I just purchased one of these on EBay. It had 8 x RE 7393 steel core
transformers. Two of these were damaged so I had the two damaged units
replaced and two other adjoining units also replaced with Jensen JT-11's.
I'm balancing the I/O of a pair of RNC's with these. I'm liking what I'm
hearing. The differences are subtle...........a smoother low end with the
Jensens on first listen but both types are adding something I'm liking,
especially when these units are usedin the normal operational mode where
color may be a desirable factor. Anyone have any history on Underscore
Electronics or any info on the RE7393 steel core transformer? Just curious
more than anything else and a Google search isn't getting me anywhere.

Thanks,

DJ
