+1 on the vintage Infinity
I have a pair of original RS-II. I rebuilt (and modestly upgraded) the crossovers.
They are excellent speakers that imo outshine a lot of what's on the market today, when they're in good nick that is.
They need a LOT of power if they're going to give their best though. I have Classé monoblocks driving them, they're a good match but honestly big Krells wouldn't be out of place.
IRS Beta next...?
