You have listed many fine choices. However, one of the best sounds I got out of my magnepan 1.6 speakers came from a vintage luxman R117 receiver. You could probably get by with the R115 (70/ch) especially for your needs. At $100-150 on ebay. You have little to lose and can always put it back up for sale. The R117 is $200-300 and is harder to come by. Save a small fortune and buy a good CD player and use the CD bypass to go directly to the amp section.
