My amplifier, pre/pro, and 6 out of 7 speakers were originally bought as refurbished, demo, or blemished. I've already been eyeing fancy 2-ch electronics for the future and have noticed some very good deals for refurbed stuff. I think Pass Labs, etc. Refurbed stuff often still comes with warranty. Same with demo's, or at least mine did with 5-yr.
Some people think hi-end electronics represent the choice between buying a new or used car. Some like it new, and others feel that the immediate depreciation of "driving it off the lot" is not worth it. It can be a difference of thousands.
