Infinity RS Kappa 7 speakers, bought new off a dealer's showroom floor in 1989ish.They have managed to survive 30 plus years of my life, but with some wear. These were my first audiophile purchase, and are incredibly important to me.
I had the foam surrounds replaced for the woofers, Millersound refurbish the Polydome midranges, and luckily the EMIT tweeters have survived.
I had GR-Research update the crossover networks with modern and much higher quality resistors, caps, air core inductors, bypassed the pots, replaced the internal wiring with OCC wire, and added WBT speaker connectors.
They sound amazing! But I've spent several times more than what the speakers are worth, but to me it was worth every penny.
