>>I got a bit of this when I heard the otherwise very nice Soul Superfly, and when I was seriously considering the Omen Def, Sean (who is very helpful), said he could address it with a modestly priced cap upgrade.<<
There is a Zu tour stop in L.A. tomorrow evening. I had an exchange with Sean today regarding that and asked him about whether a simple cap change or cap + wiring change would suffice to address concerns of a Def3 buyer sensitive to high frequency aggression on mediocre recordings. He said he thinks it is best to do with with the capacitor change in the high pass filter, alone and that it would also fully address the problem. If the speaker ever changes hands or system components alter the nature of the problem, it's easy to revert to spec on the cap, and the full transparency of the Event internal cabling is preserved.
