I've had the 970/7075 for a couple weeks now, and at first the combo sounded a bit leaner than the 1070(s) I had previously. I don't know if it's the gear or my ears, but things are sounding rich and full now, and the lean sound seems to have disappeared. I know there is debate concerning electronics "break-in", so I'm not making claims one way or the other...just reporting what I hear.

I was toying with the idea of swapping the 7075 for a 7125, but so far the 7075 has provided all the power I've needed.
