I’ve mentioned this before, but I’ll do it again... I went through a vintage phase a couple years ago, got a Marantz, Harman Kardon, and Pioneer receiver. All of them had been professionally recapped and tuned... All of them were pretty to look at... I called the Marantz "functional art." But, it was more of an art piece rather than a great amp, when compared to even modest new gear. I put them all up against even Marantz’s little nr1200 and it blew them all away on every sonic attribute AND has all the modern functionality and hookups.
That said, I still love my Epi 100 speakers from the same era, though I've put in a new capacitor/crossover and of course refoamed the woofer (mid-late 70s). Nothing I've heard speakerwise has convinced me to part with them; everything sounds good on 'em, and they're not picky about set up with that widely dispersive, sweet tweeter that still manages to image even far off axis...
