I own a few restored vintage Marantz units (1060, 2230 and 2245) and have run a number of speakers with them. I had the 1060 paired with a set of Design Acoustics PS-10s for a long time. The PS-10s we're built in the 80s and can be had in mint condition for $300 or less (usually found on the evil auction site). I had mine jammed right up against the wall with no I'll effects. They're sealed and feature a 10" down firing woofer. Most PS-10s (I also recommend their slightly bigger brother PS10a) have either had their woofers refoamed or woofers replaced with matching spec Dayton drivers. I've used both and Dayton drivers are better. Buying a set with replacement woofers shouldn't be seen as a downgrade.
Overall a nice smooth sound that compliments the Marantz nicely. If you can find a pair with the adjustable tweeter, all the better.
