What makes you say that?
Detox and MDAC2 are the only projects we are working (asides from the mini-streamer test PCB & our "XMOS" USB development PCB to confirm 769KHZ PCM and DSD512 operation, software, clocks and dual 9038 etc).
All will become clear at Munich and the reasons I cannot give more details.
My daily "projects" consist of:-
Detox production updates currently:-
1. Crystals samples approval
2. Approval of a suitable PSU for UK / EU and US
3. BOM cost reduction and clarifying vendor details
MDAC2 Project:-
1. Approving the Crystals for main oscillators
2. Approving magnetics
3. Approving connectors
4. Approving the new Flexible foil to the front panel
5. Build an incoming IQC test jig to test the Crystals before they are used in production so we dont encounter the same failures as seen on MDAC.
I just purchased a Agilent Network analyser from the Philippines of all places for the production line in China for this purpose - but refuse to pay US$7000 for the extra crystal test adaptor* so I have to design our own test adaptor..
* there is a second hand adaptor on Ebay but its still US$3800 + shipping plus Tax and import duty of 25% give or take...

6. Updating schematic so Jarek can start work on the SOC PCB / test PCB
FDAC (much the same as MDAC2 as they share many of the same components)
1. Building an Inverses RIAA for production line testing of the phono stage (parts ordered yesterday)
VFET:-
1. Confirm DC servo operation range to balance expected DC offset of 6n23 Tube after confirming Spice models of the tubes in hardware over the weekend.
Please DON'T rush to conclusions - there are commercial reasons I cannot say more about Munich - but Detox and MDAC2 will be available
It upsets me to get such a post as I spend so much of my time currently working on production related issues - I feel relieved once I've cleared the daily Email traffic and questions etc. from Asia and I can finally get back to working on the MDAC2 Design.
As we know what components are used on MDAC2 I have already started the sourcing / vendor / sample approval...
Yesterday I placed a large component order for the MDAC2 prototype PCB (also components for the Inverse RIAA EQ & Crystal test jig)
Oh I forgot to mention not only did I just purchase the Network analyser for the production line at silly money (the crystal adaptor alone would cost used US$3.8K+), but also this week a stereo Microscope for the lab bench as the components on the MDAC2 / FDAC are so tiny - they are really designed for the mobile phone industry so have been shrunk to an almost "human" unusable size... Mosfet packages 0.77mm by 1.7mm (with 3 connection pads to be soldered to the PCB).
So yes - I'm just alittle pissed with a post like this as I've spent every working moment of the day on these projects and have pumped in FAR more funds than I've received in development funding to make these the greatest designs I can... and ironically I'm working everyday on production related support for these designs!
