If memory serves me correctly, the 2270 was bit if an anomaly when it came to 4 ohms vs 8 ohms output. The Julian Hirsche review measured the 2270's output as 46 wpm into 4 ohms. Opposite of what you would expect
In any event, I used a Marantz 2245 for years with modern era speakers. I found the best pairings to be: http://www.nhthifi.com/products/10668-classic-three-bookshelf-loudspeaker#specs NHT SB2 (I would go for the Classic 3) and the http://omegaloudspeakers.com/super3i.html Omega Super 3i (I would go for the Super 7 monitor mk2.
I never tried the Marantz with a floor stander, only monitors.
What would interest me, if you would want to try an old school designed, new speaker is the http://directacoustics.com Direct Acoustics Floor Stander.
