Can Dynaco ST-70 Drive Polk Monitor 10?

I don't think there will be a problem driving the speakers, but....

While the Polk was a great value in its day (IIRC - and it's been a long while), it always struck me as just a bit soft in the bass. Similarly, the ST-70, while a really great amp in many ways, is not the last word in bottom end grip. So....while this might not be a match made in heaven, I'd still think it would be kinda cool.

You should be fine. I drove a pair of the Polk Monitor 7b with a NAD 3020 rated at 20 watts per channel (though it was very conservatively rated). When I bought that pairing I auditioned the 3020 on a set of the Monitor 10s and went with the 7s due to size and finances. The dynaco should work very nicely.

Yup 3020/10s - first system out of college - oh, yeah, and a Thorens.

I owned the Polk Monitor 10 for about 15 years. Most of that time I was driving them with my Fisher 400 and they are ok. I now am using a PACO/Jensen TR-10 combination. I wish I still had the Fisher/Polk to so some comparison testing as the Jensen may not have the bass of the Polk but sound better for my listening choices. I have an older HSU VTF2 to supplement the Jensens when needed. If its going into a smaller room I liked the smaller version of the Polk 5JR or Spica with a tube system.

A lot will depend on the size of your room, how loud you like your music, and the dynamics of your favorite music genre. No one can guarantee your satisfaction.
