70 watts is a little weak. Something over 200 watts is preferred.

Not everyone needs that much power or can even utilize it with their speakers or their living setup. Maybe not for you, but I know this would be the perfect amount of power for my home office rig.

For me, power brings more dynamics and quality to the sound regardless of system size. But again, that is my personal opinion.

There's just nothing factual to support this. If you have speakers that run optimally at 100w/channel, the 250w amp vs the 200w amp vs the 150w amp is going to have VERY little, if any, difference in the dynamic headroom necessary to operate at peak efficiency. I agree that a little headroom beyond your speaker's ratings/measurements is important, but 70w of clean power is plenty for a lot of speakers. Distortion is a lot bigger issue impacting dynamics than just rated wpc (which is often rated differently or downright incorrectly by many manufacturers).
I'd love to see some information that supports more power = better dynamics regardless of system size.

True. That is why it is my personal opinion.

Also depends on speaker efficiency. For example, running a 86 db/w set of speakers using a 1.5 watt SE OTL amp will sound quite different than running it a pair of La Scalas with 105 db/w sensitivity. But again that is my personal opinion. The less efficient the speakers, the more power the better the sound. That is from my personal experience.
