I noticed that I rarely see threads that don't "leave you hanging" as to the outcome. I have decided to report back and say that I can't find any reason to make any changes to these speakers. They have sounded good with anything I have attached to them.
That said, I will tell you that I have moved on to finding something to push them that I like. One of the earliest threads that I read on this forum said that Klipsch speakers will end up making you want to upgrade the rest of your system and I find that true. I started out with my Pioneer SX-1250, then my Marantz 2325, both of which I like, but something was missing. I came across a deal on a Mcintosh MA6300 which I thought would hit the spot and while it sounded good, still something was missing which is hard to put my finger on, or ear.
More reading (I love this forum!), and the idea of tubes was planted. I made contact with a wonderful gentleman named Pat Hickman of Classic Tube Audio in Camas, WA. He let me check out his stock which had a museum of sorts of historic gear, some really cool equipment ready to refurbish, his lab and he let me pick his brain on some questions I had about tube audio. He's even built his own amp that did well at T.H.E. Newport show. His knowledge of tube audio spans 50+ years and he was gracious and patient and helped me on a path on which I still feel I need a striped cane.
Lo and behold a Scott 299 C tube amp and tuner are on their way to my place and then straight to him for a rebuild. The follow up to this will be somewhere in the Talkin' Tubes thread.
