Yes "acoustically focused clock" is marketing pure and simple, but it doesn't mean that the product is bad because they describe it a certain way. They just decided to market their product with a touch of gimmicky language.
A lot of big studios out there and big musician personal studios use Antelope clocking products....they have been well established in that regard for quite some time. Could all of these people be imagining an improvement in sound? People that are ultra critical of their systems and spend hundreds of thousands of dollars to get things perfect. People that listen to their systems all day long hours on end and know the sound to a "T". They are going to most definitely notice what happens when a new piece of gear is put in to the chain I would imagine. Sure some are addicted to just getting new equipment, but nearly everyone raves about the Antelope clocks in their studio if they have them/have heard them in their setup. Its not like Antelope Audio just came out of no where all of a sudden, they have experience in the industry. Sure there may be some gimmicky language used, and to tell you the truth that also almost prevented me from trying their product. But to be honest I am glad I gave them a shot as I can't imagine my system without the Zodiac+ now.
Wait until their cheaper base model comes out, and give it a demo, the sound should be identical to the + model. Don't knock it until you have heard it yourself I always say. Or at least demo one under decent conditions before you knock it.
This post might have come across as defending Antelope, but I feel they deserve it as they have put out a great product which I am thoroughly loving. Anything else I post in this thread will be informative and you should have my review next week as I will be receiving the Welborne power supply at that point.
