I really like the sound of the mid 70's late 70's equipment the best - much fuller, and richer in reproduction.
I have a couple Marantz receivers (2226B, 2252B and 2265B) that sound terrific and would work very well for you.
I also have a few integrated amp - tuner combinations that I also love the sound of (Pioneer SA 9500 II, and Pioneer SA 7800) The corresponding tuners are TX 9500 II and TX 7800.
I really like the sound of older Luxman equipment as well - they typically go for less $$ on ebay than Marantz or Pioneer. They aren't as good looking (IMO)
Luxman R-1050 is a very nice receiver, but they make many integrated as well.
Hope this helps
