@mathiasmingus I tried a respectable tube amp on the speakers and though it sounded very sweet, it just didn't deliver the "slam" that I want. Of course, amps are all very different from one another so I can't speak for what an ARC amp would do or any number of other great tube amps. The Contour 60i do demand some current to make them come alive and deliver what they are capable of. I settled on a SS amp that has a softer sonic signature than most. I bought a Balanced Audio Technology (BAT) VK-255SE. I also use the very well paired BAT VK-33SE preamp (lovely tube preamp). It's a wonderful matchup for the Contour 60i.
So the bottom line is, if you are finding the Contour 60i speakers are delivering what you had wanted then at some point make a change in your electronics that will better suit them. You have the preamp, just get the right amp to address the sonic signature that you desire. And yes, a very good power cable and signal cables are very important in delivering what any electronics have to offer.
Enjoy the fun ride!
