Jeff- Very excellent of you to pop in with good info! You da man!
I heard KXSE experimenting with their Vorsis last month. They sounded different from minute to minute, so I am guessing they were doing some A/B comparisons with their 'O' box and the Vorsis. I heard through the grapevine that GM Larry Lemansky (sp?) told the engineers to 'rip it out' and leave the 'O' box in place. Next time I attend the Wednesday lunch, I will try and remember to ask for the whole story. Entravision engineers are reluctant to discuss merits of one product vs. another sometimes.
This Vorsis removal seems odd since Entravision uses audio guru Paul Shinn to do their processing. I would think that if he can't make it sound good, nobody can.
