Hi Charles, yes I agree... as far as accuracy there are 2 things I look for. One is an absence of problems such as "lean, dry and flat", or on the other end warm, slow and bloated. Tone and harmonics should come across as natural, not stripped down or augmented. Other issues like sibilance being enhanced, harshness, edginess or graininess need to be absent. Then there is detail, the more detail I can make out without problems the better and the more accurate the cable is.
I also find beta testers very helpful. The reaction to cables so far follows a bell curve. With a less accurate cable I get a wider distribution of reactions and far more outliers where the synergy is either very good or very poor. With a more accurate cable I get a far more consistent reaction to the cable, which was a main motivation for this thread. It seems like the more accurate cable is able to achieve "synergy" with pretty much any system while the less accurate cable is far more hit and miss.
Charles, also if you have not upgraded your Omegas to the latest drivers you should do so, they are inexpensive and the latest ones are absolutely amazing, the performance equals anything I have heard, including high $ items like Voxativ and Feastrex. The highs extend to 20k instead of 17-18k and the midrange bump has been tamed, they are much more neutral than they were with the old hemp drivers. Soundstage is greatly affected by equipment with these speakers and I have no problem getting the speakers to disappear and the soundstage to extend past the physical borders of the room if it's on the recording. They are as close to point source as you are going to get and I have not experienced better soundstaging/imaging with the exception of the all-TAD system at this years RMAF, which did pretty much everything better than anyone else, imo.
