Speaker Recommendations for my Vintage Marantz 2270 and Miracord 50H MK II

EASY - KLIPSCH HERESY

The Marantz 2270 is more than capable of handling 4 ohm speaker loads.

From the 2270 owners manual:

Yes, I seen this too.  But the fact that this receiver puts out the same amount of power into 4 ohms as it does 8 ohms tells me it has a very limited power supply.  A 4 ohm speaker could suck the life out of this receiver in a hurry.  Most modern amps can almost double their wattage into 4 ohms as opposed to their rating into 8.  If it was me, I wouldn't trust a vintage receiver with a true 4 ohm speaker.

This is also why nearly all speakers were 8 ohms back in the day.

Mapleshade speaker cables are great with vintage gear, both sonically and functionally...

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.
