Thanks!! So no performance improvement, just mounting convenience?
BrianDonegan said:Hi Bert-
Usually this type of noise is caused by interference between the power wiring and the I2S wiring, or power wiring too close to clock traces on the board(s).
From your pictures, my guess is that the source of your noise is one of the wires in this picture:
Brian, it does not change the problem if I put the wires differently.
Have to redo the position of the 8804 and metronome boards I guesss. It is the highest freq. line from the 8804 board to the metronome that causes most problems.
Even coming near with my finger kills the signal.

Did you create a ground loop in any way?
Kind of thinking about just getting an Opus for the time being. My question is what would be the more rewarding choice, going with dual mono DAC's or a single DAC with a Metronome? I'll be using the USB for now... so not sure jitter is AS big of an issue as if I was using it for a CDP. Eventually I will add the SPDIF module though. Also I might swap it out for the Sabre depending. I'm just getting a bit fedup with the sound from my sound card and not sure I can wait for the Sabre 🙂
Was also wondering do you think the COD is better then the Opus? Do you like the BurrBrown DAC better then the Wolfson? They are both oversampling yes?

My personal thought is that metronome + 1 opus will be better than dual opus with no metronome.
I was thinking about buying the USB receivers to interface with a SAA7220+TDA1541A. I'm just not sure about the I2S output of the USB receiver. If it outputs in 24-bit I2S, will the SAA7220 still recognise the signal? Can I set the PCM2707 to output 16/44.1khz?
An externally hosted image should be here but it was not working when we last tested it.

It is OK now, no noises or ticks anymore.
wiring is super short and most psu lines are going under the plate.
between 2 pcb's(which are on top of each other) there is a small screening plate, earthed.

mode 0-2 setup window, its on 96khz now.
Brian, the sound is awsome😀

dual opus is just like fresh air, you just want to keep it coming
😉(I mean the music)
what a channel separation.

The metronome is less of an improvement imho.
I actually haven't tried a single Opus, but I was going to sell off my dual Opus until I got the metronome in there...it really took it to the next level for me.
I think I'll do dual mono's as with the PC I don't think jitter is as big of an issue. Later I'm going to upgrade the DAC's to the Sabre's if they can be run in mono mode then I'll use 2 of them. After that I may add the Metronome if its an improvement to the Sabre's clock.
Sound like a good idea?

Hi Dougie,
Honestly, the metronome will be a bigger improvement. You'll be getting plenty of jitter from your PC.
With the Sabre, you won't need to parallel it as it already contains 4 stereo DACs! Plus the it has it's own in-built ASRC, so the metronome will not be required.

I know I don't need to run it mono 🙂 But if I can I think I might want to 😀
I believe that they have said that using an external ASRC with the Sabre actually improved it a lot.

I very much doubt it. The Sabre's internal ASRC is better than the Metronome's.
Well then I probably shouldn't purchase the Metronome as eventually I won't be using it. My friend might purchase the DAC boards when I upgrade to the Buffalo's.
They improved the Sabre by using a better external XO for use by its internal ASRC. One of the things that makes the Sabre so attractive aside from its impressive numbers is the inclusion of receiver and ASRC.
Whats a better XO exactly? I'm somewhat new to DACs. Is that the clock? Something like a tent labs?

That makes sense. Your friend will be getting a good DAC, but the Sabre is rather special.

I'm a little confused ... who is "they"? RossL and I have reported mods to the Sabre eval board in the ESS thread. Has anyone else reported anything?
