@joeradio - For "all things" vintage Infinity, go to the Infinity Users Forum at AudioKarma. Lot's of vintage Infinity aficionados there. They will offer guidance on appropriate amps and repair/replacement of EMITs.

@ishkabibil - I have 2 vintage Infinity Speakers that use EMITs - Infinity Qb and RS1.5. I do not find the EMITs "steely" in either implementation.
