Yamaha RX-V581 or 681 - Help please

[HDTV1080p]

Hi,

I am confused about choosing the right AVR from Yamaha, between 581 and 681. Which will be having the best match with my custom 7.2 sound system comprising Bose acoustimas 10 (5.1) + Bose acoustimas 5 (2.1)?
I was told by the Yamaha customer care representative that both are having same wattage of 600 watts but 681 has high ampere rating for which the sound output will have much clarity.
My (dedicated) room dimension is 25 x 9.5 x 10 (L x W x H in feet)

If you have the budget, do go for RXV 681. Its far better in terms of connectivity and latest decoding techniques.

Can you please elaborate on those important differences?
