Thank you!There you go:
Hi John,
When do you expect to start receiving and by what date is first instalment due.
The £125? for those who have signed up already?
Any ideas?
Gotta get my money ready!!
Hi John, sent you a PM some days ago with some questions regarding the mdac2 pcb board... Would appreciate if you can reply when you have time, thanks!
I am a proud owner of an mdac. I am from Costa Rica, and am interested in the mdac2 pcb... But have some question that I hope you can clarify me in order to take part of the wiki-list
1- how do I pay the monthly payment of 100 pounds? (Credit card?, wire transfer?, etc)
2- how many monthly payments do we have to contribute?
3- when is the pcb for the mdac2 estimated to be shipped?
4- how is it going to be shipped to Costa Rica?, and what do you need for the shipping? (Since Costa Rica is such a small country, in case there is other member on the list from here, we can arrange a single shipment to save costs)
5- how much improvement can be expected from this mdac2 pcb versus the original mdac?, let's say for example, 15-20%?... I can imagine it is hard to measure
6- this question is related to my current mdac... Do you recommend turning it on and off each time it is used?, or perhaps leaving it on all the time is ok? (I listed almost daily for 2-3 hours)
Does anybody tries the eclipse a502 TD power amp ? I've got the opportunity to buy one to fit with my RS1 and MDAC.

Yes, what Mr Purite is conveniently forgetting is that transparent is a relative term in hi fi, not an absolute. When listening to good kit you only become aware of transparency limitations when you hear something even more transparent.
Transparency in audio is a theoretical notion.

Hi John,I like to target the first units being shipped around Christmas (so we can gift ourselves ) - but its fair to expect sometime between Christmas and February 2014 ...
Hi John,
I'm also interested in the MDAC MK2 upgrade but I would like to clarify some questions on which I was unable to find answers here:
1. Will I need to send back the old MDAC mainboard after upgrade or not?
2. Will the MDAC MK2 upgrade incorporate the stepped attenuator (like was planned for MPAX) or not?
3. Please explain how will operate the digital volume control in case of DSD?
4. What kind of USB chip are you going to use in the MDAC MK2: XMOS or VIA VT1731?
5. Are you going to use in the MDAC MK2 design a digital isolator (like ADuM1401) in order to provide galvanic isolation from PC?
6. If I understood correctly the MDAC MK2 will use the same external power supply as original MDAC. There are any news regarding fate of the MPAX in connection with the MDAC MK2 project?
Thanks in advance!
Nick
1. We would prefer to take ownership of the original mainboard after the swap.
6. M-DAC 2 being a mainboard swap for original M-DAC will keep on utilizing much of the original M-DAC chassis and accessories including the outboard transformer unit. The internal power supplies are significantly upgraded on the new mainboard though.
Have a nice day,
Dominik
If you want to take ownership of the mainboard maybe offering a small refund on return (as it is saving you money and is useless to the current owner).
