Rekindled my audio pastime. Bought speakers, good deal. Bought amp, touched speaker wires together, blew amp. Fixed under warranty, whew!. Heard a strange fuzziness and ringing..sent inter connects back and passive preamp back(that I now don't need and sold) nothing wrong. Never did figure that one out. Sent in crossover because of fuzziness/ringing. Got new op amps and a checkover for $160, a bargain. Cat busted off my banana plugs on my speakers twice, now have spades. Nice vender fixed for ZERO. Bought streamer on Amazon, then bought Bluesound. Sold original for almost new cost. $10 loss, another whew! Making homemade sound panels on the cheap and buying cheap bass traps, Loss of $300. So moral of the story is I dealt with good people and it didn't cost me much except chasing phantoms and changing gear in and out. And now I have about $8k in everything and it sounds pretty darn good!! All comes with the territory and it gave this newly retired guy something to do last winter.
