Lynx Aurora clocked with INT AND EXT with Ishochrone.

[Nu-tra]

Hello everyone.

People have been asking what effect the Antelope Audio Isochrone makes when clocking the Lynx Aurora.

I played bass on both tracks directly into a brent averill 312 into my lynx aurora 16.

Isochrone- bass was clocked by the Isochrone with the lynx converter set in "EXT" and synchro lock in the OFF position.

Aurora- Bass was clocked by aurora and set to the "INT" position with synchro lock ON.

This was done in logic and played along to a click track. I know its not a perfect test because it's two different performances but you can hear what the effect the clocks have. One is harder sounding than the other.

Yeah I'm bored.

I just listened on headphones.
I prefer the bass with aurora internal clock. Bass seems more full, natural.

FWIW my rig is apogee16XDA clock > aurora16 on internal > aurora 16 on internal.
this seems to preserve the original source the most. isochrone made things sound 'crispy', very nice, but stereo image and sound weren't as close to the original source as i would have liked.

my isochrone is retired for the time being, but i look forward to trying it with the atomic clock. i've heard very good things about the atomic clock.

strange and thx isochrome....

hm strange i think your chain isn't that bad but I'm instantly thinking of 56kb/s mp3s or something if i listen. (please don't take this as offence ) it's just the way i feel...
So it's really hard to judge on these also if it goes to such a special topic as clocking....

ocx ?
what BNC Wordclock cables are you usign?

the difference its incredible when i hear both with a hi-jitter clock.
aka. onboard soundcard.
but hearing both with my <1ppm clock 15°-30°
the difference its less,
becouse the jitter accumulative effect.

here the "ocx" file sounds more crispy, but seems a bit weaker lows.
the other Lynx SyncroLock(TM) file here sounds blurry mid bass. but stronger.

thers another berrillium atomic clock from: teac esoteric g-08Br
and can be upgraded to military grade spec. celenium-144 or hydrogen atomic clock.
...
P.S.
i would like to describe the sound of my drawmer m-clock
when listening .mp3/.wav or image files of DVD or HDCDs:
it makes almost everything sound verry transparent, louder and wider,

makes my lynx aes16 syncrolock(TM) sound harsh.
and makes my rme steadyclock(tm) sound thin/weak, like when you see the bones of anorexic people.
the Alesis Ai-2 sounds like has missing mid-bass, and its not as louder or wider, but verry sweet also.
thats how i feels it sounds to me,
testing A/B with some songs.

but have noticed that my Drawmer M-Clock EQZAL TCXO crystals are verry sensitive to room temperature. if nothing else in the rack.
when room ambient temperature its over >22° sounds super transparent and louder with strong mid bass & lows.

but if room temp its near <16° sounds worse than my RME, a bit less louder than RME and sometimes has moments of Greatness, verry weird
bad,bad,bad,GREATNESS,bad,bad,GREATNESS,bad, etc...
the Temperature Controllers inside the EQZAL Crystals cant keep up with a cold room surrounded by all that cold steel and aluminium of the rack.

love my m-clock but, im starting to love that crispy sound of the ocx
first, i would like to buy a psaudio powerplant, or furman it-20 II + ar-20 ii or PF-PRO ii + ar-15 ii, or Monster MPP7000 + avs 2000 pro
to clean and stabillize the AC 120v 60Hz line from ground loops and EMI & RFI, to improove my drawmer a bit more.
the AC line its not the best here, but Drawmer gives great results.
anyway,
nice test
thanks

It's a 75 ohm bnc cable.. it's a word clock cable. I'm selling my ocx cause I need the money if anyone is interested.

sounds great, but too much money.

[Nu-tra]

I haven't quoted a price yet... So it might not be too expensive.

The aurora sounds louder. That effects the test unfortunately. I did adjusted the volume myself to get an accurate representation. The aurora sounds muddier or blurrier to me than the antelope. The Isocrane sounds more defined and less mud.

I have tried many converters and a few clocks. I never found an internal converter that I really liked enough to sell my big ben. I agree with the price. Big Ben is bad enough. Antelope my god!! NASA price. but with NASA results???

Thanks for the post.

[Nu-tra]

Yeah the atomic clock is like $5000 plus you need the ocx to run it which is another $1500. I never touched the levels btw. I did a int and ext bounce. I thought the lynx was louder...

[audiovisceral]

fyi, i e-mailed lynx and they said the aurora outputs a 30 picosecond jitter clock. the best are < 10 ps, so the aurora's actually pretty good for a master clock as is.

[Bang]

to the original poster.. did you turn off syncro lock in the Lynx Aurora software mixer AND the Lynx LMixer (if you use the AES16)? This is the only way to clock the Aurora externally.

Lynx SynchroLock(TM) 44.098khz

get:
lucid genx192 +-25ppm
or alesis ai-2 +-50ppm but only works at 44/48k
or Black Lion Audio MicroClock 10ps
or betters... Drawmer, Mutec, dCS, teac esoteric, Antelope, Rosendalh, Mytek, etc...
with 99.997% OFC cable for 44/48khz and pure silver for x2 x4 sample rates.

That's crazy, the clock on even the inexpensive Mytek converters clock to below 10 picosecs, the Microclock by Black Lion Audio is below 10 picosecs and although Apogee doesn't report how low the Big Ben can clock, I've read reviews where people have tested it and apparently it's in the low 20's, which apparently doesn't matter since at anything below 50 picosecs, our human ear can't detech the build up(probably even higher than that). I remember the Aardsync II wasn't really too low on the picosecond marker, but it had a color that people liked, harmonically. The only thing that really affects us mixers is that things become smeared and it becomes harder to create depth and space in a mix when the clock isn't as good. I've heard the Aurora clocked internally and it sounds darn good that way. I think it sounds even better with the microclock attached to it. Probably due to the harmonic content the microclock induces or bring out. In any case, there's a feeling of refinement with the microclock attached that gives an impression or sensation of deeper and more spacious. Just my two sense from experience. Also, I liked the Lynx's clock internally before I got my Ergo from KRK, but once I hooked that up, all things were revealed and I definitely like the Microclock over the Aurora's internal clock.

Hey- what about recording playback a 1k sinewave generated in software at-1dB? Let's look at the FFT of both cases to see which one is more distorted.

clock jitter affects the harmonics,
sine waves dont have harmonics.

jitter also affects sampling, easy to see with high frequency saw waves, that are not affected by the Nyquist sample rate.
