Yamaha A-S701


does anyone own this integrated or have experience with it?  I have a 20+ year old Yamaha RX-770 and am curious if this would be an upgrade sonically.  the RX-770 sounds pretty good but don't know how much longer it will last. anyway thanks for any info.

dhpeck- would love to do that but beyond the budget!  I'm sure your correct about the others being in a different league.

willland- I have a Schiit Bifrost 4490 DAC which I really like.  I'm more interested in the comparison between the RX-770 and A-S701. these days I listen exclusively to streaming music. MacBook Air > Schiit Bifrost with Nola Boxer speakers and the RX-770.  probably not many RX-770's around these days. I guess the only way to find out is to order one somewhere with a good return policy.
hi loomisjohnson, what was your gear with the as700?  the RX-770 isn't bright at all, very neutral.  
I know that the A-s801 can be had discounted, maybe close to the price of the 701. The 801 would provide more power, however i am not sure of other differences.
