If you check out the Rainmaker frequency response, it is indeed rising at the top end. They are voiced/designed specifically, one either likes it or not I suppose(In contrast, the Totem Hawk have a much flatter frequency response). I’ve now owned 3 pairs of Totems, and I can attest to the fact that they respond to cables if the electronics are up to snuff. (Oh, you're the james that's been attacking me for daring to not like Tekton speakers, hopefully you can be reasonable in other threads.)
It all depends on one’s tastes. I’ve now compared the Rainmakers to every other pair of bookshelf speakers I’ve got, and they have a sense of being at the concert that is striking. But I would suspect with some electronics I wouldn’t like the result. I had a bright Onkyo integrated, and also an Emotiva amp that was too, those would not blend well with these Totems. My current integrated, the Nad C375BEE has been described as somewhat warm, and I agree. For me the result is good, but I want to be careful about not overdriving the speakers.
