less mass and more transparency.....
If my only option was HO, I would abandon MC altogether and go
with Soundsmith MI or an Ortofon MM like the 2M Red or Bronze, but
the quintet is lower in cost.....
My solution with my current cartridge which is .1MV is a Hashimoto HM7 stepup transformer, run into my phono pre @ 47k which is giving me the most transparent and organic analog I've ever heard......but I'm sure there are phono pres out there that will handle .3MV just fine....
Thanks
