I have a chance to get a set of Infinity Interludes at a great price. The ones I'm looking at are the IL40s for mains, IL25C center, and IL10s for surrounds. I am also considering a quintet of NHT SuperZeroes or (if I save a little more money) the nOrh 4.0 package. Could somebody describe the tonal characteristics of these speakers after break-in? I have a rather bright receiver (Kenwood VR-407) and am looking for a laid-back speaker to balance out the sound a bit. I would also appreciate comments on which package would be the best, although I already know which one you'll pick Also, are there any tonality differences between the old SuperZero and the new SuperZero XU?
