Rgs92, You are absolutely correct. I have been listening to a good number of PCs (up to $6000 retail), and there is always a compromise or two somewhere. What's worse, is that PCs can negate some of the desirable attributes of other components. I now believe that a conventional PC cannot get it all right, including:
1) Deep, defined, appropriate bass.
2) Clear and robust midrange with proper decay and no grain.
3) Open, extended, clean top end that seems to go forever.
4) A sense of forward propulsion and energy.
5) A huge and deep soundstage with no sharp edges.
6) Proper balance and a natural presentation, so nothing sticks out.
7) No haze, so it seems like you are sitting in front of the performance.
I currently have a prototype PC from a new company, that uses very unique technology. It is as close to getting 1-7 correct as I have heard. The benefit exceeds that of changing a component. The final version is currently in production, and I should have it within about 2 weeks. Anyone looking for the ultimate PC should wait a little longer. I am not convinced that there is an acceptable PC on the market currently.
