You guys are seriously awesome! I have to laugh because I'm typically guilty of requiring exacting details in order to give an accurate answer.

I've mentioned in 3 or 4 posts that I don't know the amplifier....I simply pulled the Sonos image and the amp image off the world wide web. I don't know the amp that was used and we did use a Connect.

Also the problem is fixed and I'm not worried about that anymore. I'm just trying to figure out the best way to improve the sound of the Yamaha because the vintage amp was considerably better. I would love to throw separates in or put in a $3000 amp but that is not in the budget.
