Hi. I have a new pair of C7s mated to a 15 year-old McIntosh MAC4300 receiver. SS, 100 w/ch. Perfect match, for all the reasons that you list in your post, especially because it provides the bass response that the speakers need.
While my MAC was out getting its routine 5-year service in Binghamton, I hooked them up to a 25 year-old Marantz 2225. Even 25 watts drove them beautifully. These are fabulous speakers that will make anything sound great.
As for stands, I have them on 24" Sound Anchor four-posts. Frankly, I hate the looks of the stands, but they do the job better than anything else I auditioned. Tellig's review in Stereophile said mount them on cheaper, sand-fillables, but I disagree.
I agree with the poster who said that Naim components make a good match with the C7s. I auditioned them on Naim, CJ and VAC amps.
