good integ amp match for Spendor S3/5r?


I may be purchasing the Spendor S3/5 r monitor and would
appreciate advice on a integ amp that matches well with
these speakers. I have a budget of around $500.00 used.

I know these spendors are not the most efficient, so I am
assuming I need lots of power, like 80-100watts?

How does NAD, Arcam, Music Hall or Cambridge Audio work
with Spendor?

The quality of the watts are more important than the number unless you want to play at a very high volume much of the time. I have 6 pairs of Spendors but not that model. NAD gives you a lot for your money; if you can find any of the BEE models in your price range they would be a good bet.
