Manhattan II vs 8x192 Clock

Hi everyone,

I have a Mytek 8x192 ADDA which I am using for tracking and feeding my chain.
I recently got a Mytek Manhattan ii Dac for monitoring.

I see on specs that 8x192 uses a CX-797 clock with an internal jitter lower than 10picoseconds.
While Manhattan ii uses a Femtoclock with 0.82ps (I guess that's picoseconds too).

Both units connected to pc through AES using an RME HDSPe AES card.

So my question is which device should I use as a clock?

I've read that it's better to use the AD converter's internal clock when recording so I always clocked from my 8x192.
But now I got the Manhattan ii I am wondering if there will be any benefit on clocking from Manhattan due to the lower jitter..

Or Maybe I can use both, Manhattan for mixing and 8x192 when recording? Any thoughts?

I am currently building my studio so all units are packed and stored but I will surely AB them once there is some dust free space to use

Typically you want to clock from the ADC.

Yes, that's what I am used to also.

Quoting from Manhattan's manual:

Quote:
We recommend running Mytek on Internal Clock, using the built in Mytek FemtoClock which is by far superior (<1ps jitter) to any clock source connected from outside.
Incoming signal is synced to the converter’s ultra-low jitter internal crystal oscillator. This choice assures the best DAC performance and is superior to any (even Atomic) clock supplied from outside because of its close proximity to DAC clocking chipset.
And 8x192's manual:

Quote:
The built in CX 797 clock generator with multiple wordclock outputs is the best source for stable studio house clock, and the 8x192 will perform best using this internal clock.
It's recommended that as much as possible the unit should be clocked from its internal CX 797 clock generator. This mode offers minimum jitter allowin for the best performance and system stability. Associated equipment should be slaved to 8X192 clock outputs whenever possible. There is no measurable improvement (rather typically a degradation) when the unit is clocked by external clock generator.
I understand that each device performs best with internal clocking.
So I guess it's wise to take advantage of Manhattan's ultra low jitter and clock from this one when mixing,
and clocking from 8x192 when recording.

See if you can hear a difference. That DAC is likely very jittery immune.
