Interesting if not OT banter on vinyl v digital. I built my brother a reasonably tricked Ian canada streamer....trafo output....good but not crazy good psus. Plenty rails. Cost maybe £500 and yet to do Andrea Mori clocks. He has a Brinkman bardo, alnic, avalon system. He hears the difference but at the price difference the digital is a good return for the money. Very good.
As you can clearly see, as long as you don't have a catchy story to add to your results, nobody gives a **** on your results in this thread.
Not quite- I am. In particular on the 10 MHz it seems one oscillator was right at the noise floor. What determines the noise floor? The reference oscillator or the noise of the ADC's?
Are there spurs from the switching supplies that are suppressed?
Any suggestions on getting the most from a Timepod?

I'd argue it is spot on topic. The original premise of the thread was great sound from digital demands a SOTA low phase noise oscillator. Confirmed!
There are no easy answers, take a look at this:

Spurs appear to be mostly mains frequency harmonics (multiples of 50Hz, Gerhard is in Germany).
No I mean sonic spectaculars such as 'direct disco' and 'The sheffield track record' really are rubbish and only good for showing off to your mates how good you think your system is.
Anything wrong with Harry James for example?
Harry James is not my cup of tea, but I can see that being one of the few that shines out from the sheffield labs catalogue as being worth >1 listen.
Learned a lot from that paper. None of this is easy. Also mentioned in the paper are the extreme efforts to eliminate external influences- shielded room + serious power filters etc.
Still we are a long way from connecting the measurement to the audio output of a DAC.
syn08 with all due respect I beg to differ. I'm not sure anyone is using these clocks because of a number or the brand of the tool used to produce a number.
But almost unanimously we have been rewarded with substantial leaps in sound quality as the quality of the clock signal improved. As I went from FOX to NDK to NDK SDA to WTMC v1.0 or to WTMC 2.0 each step you wonder if you've reached the point of diminishing return. But no, its been surprising how much impact phase noise has on even a 30 year old R2R chip.

No. Extraordinary claims require extraordinary proof. I'm making no claims just pointing out that the plural of anecdote is not data. I don't care if people built instrumentation grade clocks for their DACs and like them, but I have an issue with all these claims of SQ improvement based on sighted listening of something they have proudly built.
