DeVries,
I have a collection of old receivers and amps in my garage. I'm running an SX-939 and a Sansui AU-717 through M2s and they sound fantastic. I had a pair of M3s but sold them. The 717 has been used in my 2 channel setup but is now in the garage since my Emotiva XPA-5 arrived.

We toured the Midway 2 years ago and yes, it was unbelievable. What a ship it must have been. I was infantry VN and we appreciated all the support we could get!!!
