I realize this is an old thread but wanted to add some information. I've owned one for close to twenty years and yes they are very good and they are rated at 185 WRMS per channel at 8 ohms but also rated at 240 WRMS per channel both channels driven continuously at 4 ohms with 0.05% distortion and they rated them conservatively. So these are very powerful receivers and sound very good, almost tube-like. I use mine with two pairs of Large Advents and have only seen the clip light on once or twice and didn't hear any clipping and this was at a very high volume, I just turned it up that loud to see if they worked actually, so I would imagine with Klipsch they would get very loud. Bu they're reliable, built like a tank, have all discrete transistors, no IC's in these things. I will never sell mine even though they are now selling for 6 to 7 times what I paid for mine. This was the third most powerful receiver Marantz built, the next was the 2500, then the 2600. Rated at 250 and 300 WRMS respectively per channel, probably into 8 ohms, don't know what those were rated into 4 ohms. I had an output transistor go on me years ago when I first bought it and had it fixed and it's been fine ever since. It is now at least 41-42 years old, I believe they made these from 1977 to 1979.
