Earl, I beg to differ; The only time when a two way with a sub is a three way is when all the speakers come from the same company - and even then it's not the same, as I showed in my review of the Wharfdale Opus speaker line for Dagogo.com. Aside from that there can exist a vast gulf in performance between a smallish two way with a sub and a generous floor standing three way - with or without sub. One of the reasons I gravitate toward big floor standing speakers is to attain a far superior definition and detail in listening. There is an entire universe of definition/detail which escapes a large swath of two-way speakers. They are built at a price point, and they are going to be missing a lot. Otherwise, why would the market for three-way speakers continue to thrive?
Earl, I can relate; I was an ardent cable skeptic, too, about twenty five years ago. I thought people were stupid to chase aftermarket wires - until I did my own comparison and it became clear that it wasn't stupid, but was a critical way to tune systems to one's favored sound. No one would have been able to talk me into believing it, as I had to prove it to myself. I really didn't want cables to make much difference because I knew it could cost me more if they did.
By this time in my involvement in the industry I know personally a fair number of engineers and designers (cable, component, speaker designers/manufacturers), some of whom I have helped move from skepticism to bewildered belief about the ability of cables to influence sonics in a system. For some of them the only convincing "argument" was hearing it for themselves in my room.
I still remember the day I decided to try it and went to the hardware store to buy the fattest/heaviest gauge copper cable which could still be affixed to speaker and amp terminals. I certainly wasn't going to waste much money on my experiment! I attached it, listened and became a believer.
I'm not going to try to argue you into it, but I hope at some time you try aftermarket cables. They are one of the best means of attaining the resolution, as well as dynamics and imaging, which you are seeking. :)
Oh, and if you try the ATC/Bryston thing you may be reaching for those cables sooner rather than later. Further, try some aftermarket cables and you will realize that you can indeed fix what did not seem broken. :)
