Finsup: My 2-channel chain does not include any DSP. However, when I listen in surround, my AVR applies Pioneer's MCACC, and I do notice a smoother quality to the sound. Note that I run my 2000s with a pair of Vandersteen 2Wq subs with Vandy HP-5 crossovers. I have never felt the need for any EQ in the bass, but maybe it would help things.
Tobeornottobe: Fascinating post! I have often wondered what my Ohms would sound like with a pricier tweeter. Did you disconnect the Ohm Walsh super tweeter, or does it continue to run alongside the Omni Harmonizers? FWIW, I have no issues with a solid center image. If anything, it is too centered and narrow. That may be due to room treatments (mostly Auralex foam panels). I have removed some of them, and may remove more.
