Sierra 2 with Denon PMA-150H?

I'm planning on moving my Sierra 2 speakers to my office, and am looking for a new setup to power them. I plan on using airplay to play most of the music out of convenience.

I was looking at the Denon PMA-150H. Has anyone used this integrated amp with the Sierra 2 speakers? I'm a bit concerned with the power rating of this integrated amp.

Here's the link to the Denon: https://www.denon.com/en-us/product/amplifiers/pma-150h

TIA!

Unless you plan on listening very loud (or you sit very far away from the speakers) 70w is plenty.

Thank you, what caused me to question it was the 35W at 8 Ohms.

Admittadly I don't know how this might affect the setup. I will be sitting within 10 feet, and will be mostly lower level listening most of the time while I'm in the office.
