I bought this great amp right here on TB. Only reason I'm getting rid of it is because the band broke up and I can't see myself needing this much power for a long, long time. Still in great shape. Haven't had a single issue with it. Looking to get [DEL]$400[/DEL] $375 shipped for it. I purchased this from Dee-Man, I hope he doesn't mind me using what he wrote about it. "Howdy TB. I've been shopping for a power amp, got a few, A/B'd them, now have to sell the ones I'm not keeping. So, for sale only is an excellent condition Crown K1 I recently got off ebay from a 100% positive seller. This discontinued amp gets lots of love here on TB, and for good reason. It is powerful, clean, very balanced sounding to my ears, has power-saving functions, 1.4V or +26db input sensitivity selection, bridges to mono and has NO FAN so it is dead quiet. 350w at 8 ohms 550w at 4 ohms 750w at 2 ohms 1500w at 4 ohms bridged mono. 2 rack spaces high. Weighs 32 pounds. I'll try to post a pic soon but it looks like a new one, except for some minor rack rash (front panel is very clean, and a cool blue)."
