Combining an NAD amp with Revox Speakers

Hi guys, I just had a quick question and I am technically not competent enough to answer it, so I hope some of you might be able to help me...

The question is this:

Can my set-up using an NAD Stereo Amplifier ( https://nadelectronics.com/product/c356bee-stereo-integrated-amplifier/)

Run these speakers, without damaging them? (https://revoxaudio.com/product/elegance-g120/)

The reason I am asking is because the system was installed like this by our hi-fi guy; but a good friend of mine visited and was surprised by the acute lack of power coming from the speakers. He then investigated and told me that the amp lacks considerable power, and it should be able to deliver at least 150W to each of my speakers (2 in total); thus delivering 300W, whereas the dynamic range of the amp is only 200W. Nevertheless, my hifi guy is denying this deficit by all means, and is repeating that the amp is sufficient for the speakers. I'm also a bit confused by the special technical aspects of the NAD; as it seems to be able to deliver different Ohm settings and has a dynamic range...

Mostly looking to confirm i'm not frying my speakers as we speak.

Kind regards

NAD/Revox Combo

NAD Amps are designed to deliver instantaneous power well beyond the RMS rating. This particular model is meant to deliver 80 watts RMS into 8 or 4 ohms. These speakers are specced to an 'efficiency' rating of 88dB, which is about average, so there should be enough power to drive them, particularly if this reviewer was able to enjoy his Magnepans using the same amp: http://www.theabsolutesound.com/articles/nad-c356bee-integrated-amplifier-tas-210-1/

That said, those are expensive speakers, and you may wish to give them more power. It wouldn't cost much, comparatively speaking, to go find a NAD C370 that's been recapped at a reasonable price to see whether more power opens up the speakers, if you like the NAD sound. Or, maybe your pal has a more muscular amp that you can borrow to test them with, see whether it makes a difference at the volumes you typically enjoy. I don't think there's an either/or answer here. I probably would personally find the amp sufficient for the way I listen. Maybe you and your friend do not.
