My suggestion is still to jump of the whole additional clock train, all together. All the naysayers are correct in one aspect: Digital is always perfect.

The only thing that matters is how much noise/jitter you have in the DAC/Clock and how degraded that conversion step gets due to this incoming noise. (These are Hans B words, not mine of course)

Since the filter solved the problem, it is clear to me that it cleaned up some sort of noise that you had from your gear, prior to the filter. I don´t know why the noise is getting worse after a while but i have to say that i am positive that it is noise, and not about crystal/shapes in the digital signal.

The main reason to jump of the additional clocking train is the added complexity. It does seem to lower the noise floor so i am not saying it isn´t working, but it just presents a level of of complexity that muddies the water when trying to find the root issue.

Just my two scents.

And I am often wrong as well! 🙂

Good morning Paul,

What makes you think I never have replaced the clock? 🙂 To keep it short the problem also appears without the clock.

Indeed normally burned in cables would be better. Untill you will come to this certain level. It's about the complete stream, when I only use one or two high grade power supplies then there's no problem. This makes it better and there ain't any issue at all, but when you take it a few levels up and use up to 8 Farad power supplies. Then the stream becomes too stable and clocks (even normal crystals) will interfere with each other, They probably will work together and the problem is born.

I'm in close contact with the guys from Pink Faun and also the electronics designer. I also had 3 different Pink Faun streamers, actually four or five when I would count some modifications. I also had an audition of different ultra streamers with different specs. They wanted to know which I thought sounded best. I was pretty clear about my preference and they have followed that advice, which means one clock in the ultra streamer sounds better than more. This is about interference.

In my own Pink Faun streamer I have tested one to 5 clocks. With only one clock it sounded better.

For what concerns the powersupplie of the Pink Faun ultra streamer it's really on a high level. But still every Farad power supply is superior. I think the Paul Hynes just makes enough noise to prevent problems with dark sound. Feeding the option modules with the internal powersupplie of the Pink Faun streamer solves the problem as well. Also the first edition Farad power supply brought less problems.

Hi Tobias,

Of course you are right about the digital aspect 🙂

But what if the signal itself is the carrier of data which is clocked at 25Mhz, while the dac runs at 24.576Mhz

It actually seems pretty logical that making this 25 Mhz to stable and present that it can cause trouble for the DAC clock. This also happens without the special clock switch.

The filter will smooth the blockwave in a more sinus looking wave, which has less steep edges. Think about this. Also that when I connect things that it sounds near perfect in the first hours. Normal noise would interfere at once.

It's a pity that a forum cant show actual sound. It starts at a very high level, for streaming terms better than I ever heard. It takes a system to a complete new level. Until the dark sounds kicks in.

What i have learnt is that it doesn´t matter what speed it is clocked at earlier in the signal chain since digital isn´t a continuous stream of data, across devices like that. The whole idea with digital, and why it is a genius format, is that the packages can come in whatever order and state they want. It will still be rebuilt perfectly in the last DAC according to its clocking capabilities, unless those capabilities are degraded by noise. There isn´t less job for that last clock just becuase the data arrives in "better shape", it rebuilds it the same regardless of how it arrives. (as i understands it)

yes of course, but still I think we deal with two different aspects. One general noise related and one clock 'noise' related.

The packages are send by a clock. They have a certain pace. No matter the order they are in.

When I add a switching powersupplie to the switch. The noise problem became worse. This is audible, but the clock problem becomes better.
