A good suggestion would be a Harman Kardon HK3480 2 channel receiver, it is 120W per channel has provisions for a subwoofer which is highly recommended to fill in the lower octave missing out of the La Scala's frequency response. It can be had very reasonably and has killer looks and performance using today's technology.
I purchased a B stock one directly from HK on eBay or AudioGon for like $180 or so shipped to me, it had a few cosmetic flaws but performance and operation are 100% and it sounds incredible. The HK3480 was replaced with the HK3485 so the 3480's were offered at good prices. I think the HK 3485 was selling in the $500 range.
