FLAC N DAC

My KG-4's have foam from top to bottom on both sides. They are open through the middle, expected I'd think considering the passive radiator design. I'd never seen foam inside a speaker before. Fiberglass, wool batting, poly batting, never foam. In contrast, a small set of Infinity's was stuffed, and I mean stuffed tight with poly.batting.

I had my KA-8006 done by Wargo's in Pennsylvania. No regrets, it has worked perfectly for the last year, often 6-8 hours a day. It was a hot mess, bad power switch, scratchy controls. It came back with such sweet tone, and depth. I'm not in any hurry to look for another amp. I had a KA-3500 done by a guy in KC,MO. That came back punching above it's weight, again very clean, dynamic. Added a thyristor mod to the power circuit to protect the unobtainium power switch. I think that's the thing about refurb/restore. Modern components can bring equipment back to what the manufacturer originally intended, and keep it there. New technology, incorporated correctly, can make it just that much better.
