Default Best clock for 192\'s?

I have Mac dual 1.8 G-5, HD Accel 3 and one 192 with 16 analog ins and 8 outs( as well as the AES, ADAT, optical, etc...)I mainly use my syste for tracking live instruments, bands and such. I have read the white parer from Digidesign about clocking and jitter. I have heard from apogee about their Big Ben, and Lavry about their 4496. I also know there is Lucid, and Benchmark stuff out there and probably others.
My question is -
1.) Do I need an external clock?
2.) What clock is the best?

Not to sounds like a jerk or unappreciative, but I am hoping to find those who have experiences with clocking and jitter, and as I hope not to have the brand name wars, just the facts.

I'm a big fan of Apogee, so I would say, you would not go wrong with the Big Ben.

Frank,
Thanks, but as i said in my post I already read this info. Digidesign is showing in this paper that their unit clearly has less jitter then Big Ben, but people say they like apogee Big Bens. Go figure.

Marvinbass,
Have you read this before? http://akmedia.digidesign.com/suppor...tter_30957.pdf
I am curious what you like about your Apogee unit? Did you try other units before going with an apogee? Have you done any tests with and without your apogee unit? I have a Big Ben demo unit right now at my studio and I have A and B the 192 to the Big Ben. I think they both sound good, although they are both different sounding. I don't think either of them sound bad, they just sound different. If you look at the link I sent you, you'll clearly see the 192 has less jitter then the Big Ben. Not to say the Big Ben is bad or anything like that. I liked the Big Ben and I liked the 192 from my tests. But I thought it was interesting that so many people say Apogee, Big Ben, but then here in plan black and white you can plainly see the 192 has less jitter. Maybe we like the sound of jitter?

Hi,

you should stay with the 192I/O, no need for a external clock.

But if you are aiming for a second interface or a additional interface connected to the digital inputs of your 192 I/O
you should rethink this...then I would advise to buy a Big Ben (or a Apogee AD-16X).

Best,
M.K.BEAT

Hi Bill

Very interesting question. I've been mulling this one over for a while now, I have been clocking from my Apogee convertor since I went HD a few years ago even though the jitter specs suggest I should go from the 192. I have briefly tried using the 192 as the master but I can't honestly say I am hearing any difference - I just need a bit more convincing to switch to the 192 clock permanantly. Will be interested to see others findings.

I'm interested in this as I have a 192, Rosetta 800 and Big Ben. I'm not sure you can just look at figures though.

I originally used the Big Ben on a mix sytem, which included some of the lower quality Digidesign converters. It seemed to make a huge difference on this setup at the time. When I moved to HD with the 192 I found it a lot harder to make a judgement and maybe I am just swayed by what I am used to. All I can say is that there is a slightly more pleasing sound to my mixes if I have the BB clocking, but not worth the admission price if you don't already have one.

Is jitter a form of desirable non-linearity?

Is it possible that we're perceiving the audible experience of greater jitter levels as "warmer" "wider" etc?

It's the same "fuzzy" logic (...) that makes many audio engineers describe higher levels of THD in a signal as "warmer".

Same applies with tape machines, which produce far greater timing jitter due to the mechanical/physical/chemical properties of this sound reproduction method, yet many prefer their sound, describing it as "warmer".

This discussion is after all about the ultimate purpose of PT - quality sound reproduction. Even if certain phenomena and listening preferences might seem "counterintuitive" as the paper suggests, I strongly believe that an in-depth examination is due in this case. The results might be surprising to all parties.
