Thank you!
Well, now I've got something to do on my days off
Michael,
The Clock circuit is a "basic" derivative of the MDAC2's clock circuit - basically to evaluate the sonic effect of the Phase noise optimization circuit, as I mentioned before its still developmental / buggy.
To power up the MDAC it needs to be set to minimum (notice the arrow on the blue trimmer points to the black marker spot):-

And during use I'd not turn it up much past the setting indicated below to prevent drop-outs on SPDIF or USB "lock up" events:-
https://www.dropbox.com/s/9fqa4vlprulr17i/Suggested Max.JPG?dl=0
I worked again on the circuit before its was shipped to you (its why I missed the Tuesday shipping deadline) - you can see modifications to the PCB between the two photos - but basically the modifications will have changed the Max level before the USB "locks up" with a resultant "dirty continues tone"- so you will have to experiment to find the Max working level for yourself.
The Clock Phase noise optimisation circuit will interact with the Detox's decorrelation circuit so Max levels of both will depend on each others level...
Happy experimenting and listening!!! It could all go very Pear shaped for me if you cannot hear any positive effects...! in my short time listening, the Detox decorrelation level had a bigger effect then the level of the DAC"s clock optimisation circuit... but I was having to come to terms with the major sound quality difference of the Superior DAC in the first instance... it was not in well controlled tests.
I also had the habit of increasing the level to beyond "reliable" operation and every so often would experience a USB lock up event (you need to cycle the MDAC's USB input to restore operation)...
The Dac's phase noise optimisation was odd - first Renata would prefer Min then later Max... we really needed more time listening (we only had a couple of hours) - but I have to balance working on the MDAC2 PCB design for any hopes of meeting Munich...

I had a buyer tell me the same thing. Tried to sell off my "stake" several months ago without much interest. It's both a mixture of frustration and dropping the hifi hobby entirely.

CrazyindianZA,
Once the MDAC2 is available for sale we will try to accommodate those who wish to pass there position on - we will try our best NOT to sell new production slots until either units have been shipped to there owners or the position passed to a new member.
The propriety to be in this position is to have MDAC2 ready for sale.

JohnW,
Just bought my tickets for Munich. Will be booking the Hotel rooms next. Would be good if we could be in the same Hotel and share your Mafia mobile to the show.
Let me know...
Keep up the hard work and the hell with the naysayers
No way. This is the best entertainment I've encountered in ages. As I've said before, I'd willingly pay an entrance fee.
Does my presence on this thread cause you a problem?

Cheers. Remind me to file you under chaff ;-)

Also don't forget to start a list of those who might need to buy an MDAC donor, since some of us have ditched ours assuming FDAC was coming instead... One in US voltage for me.
An unsurprising comment.
Let's keep personal animosity out of here. I have no personal animosity towards you.
My alternative reply would probably have been very condescending
Walk the talk and get a £50 Detox development it is going to a good cause and you can always write of the cost if you don't want the actual product.
Not at all I can live with a bit of noise.

And the UK flavor of cable thread is fuse threads. A thing we don't understand here on the continent

John,
Thank you for the kind gesture. It was not expected but appreciated. As I get older, I find that I want to spend more time on active hobbies so have largely sold off my standalone components. I have made the mistake of buying a pair of Devialet Silver phantoms but am also selling these off.
