Any shipping involved?
Sometimes that can kill a deal.I'll say this much its a handsome SOB!

If anyone else comes up on this post, I have a Kenwood KR-4600 that has been recapped/refurbished with some larger caps in the power stage etc and it sounds incredible. Craps all over the Yamaha as-701 that it replaced.
The sound from this unit is so musical, leaning warm and the perfect personification of 70's era hifi golden-age.
I'd put it up against an integrated of today, valued at $2k brand new and I'd be extremely surprised if it was bested by it in what matters, how it sounds. Not how many wpc it has.
The Yamaha as-701 that it replaced, had more than double the power rms, but less than half of the musicality.
Bear in mind people, even though the KR-4600 has about 30wpc rms now, it's capable of delivering more than double this, for short bursts. It's never going to power speakers well that are more demanding than say continual 100w rms minimum, speakers, but it was never designed to do so.
