No larger unit, as of yet.  However, we are cooking up a bigger unit that will include an atomic clock inside for release around the end/first of the year.  It will come in the 10-12K price range.
 


Atomic clock? Could you please elaborate. Sounds very interesting.

Yes that is very interesting. On the datasheet provided above it states "De-Jittered, re-clocked digital audio outputs". If the signal is de-jittered that means these existing units already produce a perfect clock signal. So how can an atomic clock provide a better than perfect clock signal? Either: A. the datasheet is lying or B. the atomic clock version will exist for no other reason than to fleece you of your money or C. Both of the above.

I am listening to the LCD2's on a Zodiac Gold this minute. Incredible imaging and musicality. As good as the reviews are on the Antelope products, I see very few reviews stating how the Headphone amp actually sounds. Actually, I don;t remember any.

Hi Gregorio,
 
First of all, there is no such thing as a perfect clock signal.  Every clock that exists in the physical world is subject to aging and drift.  The clock inside the Zodiac is a crystal type clock that's oven-controlled and it's our best yet, which is used in our Trinity (popular in many top studios).  However, most studios using the Trinity also use our 10M Atomic Clock, as well to clock it.  The reason is that atomic clock aging occurs in a more stable manner than crystals.  We make a 10M with many outputs so that studios can feed multiple rooms from one 10M clock and not have to pay for that level of stability over and over for each room.  This is the case at many facilities, including Metropolis in the UK, see here
 
The purpose for putting the de-jittered digital outs on the Zodiac is to make it possible to feed another DAC of choice, in case one prefers another DAC for certain source material.  What we've found is our DAC inside the Zodiac, as well as the headphone amp, are of such high sound quality that many users forego the need for feeding the de-jittered outs to other converters or digital headphone amps.  It's an option that's there for those that wish to use it.
 
Best Regards,

Marcel

Thanks for your response. If I understand correctly, you are saying that a perfect clock signal is impossible, in other words, it is impossible to remove all jitter. Therefore your datasheet for the Zodiacs (and the last paragraph in your message) is incorrect when it states "de-jittered digital audio outputs", it should at best state "reduced jitter digital audio outputs".

Thanks for clarifying.
