Yep. Though I've definitely been conned out of a couple hundred quid (I guess), I've received at least that amount worth of comedy value on this epic series of threads over the years to compensate....
Tragedy + Time = Comedy, unless of course your £3k in... in which case Tragedy + Time =Tragedy

From Lakewest FB page:
Update on project progress, I started working on the FPGA development for FDAC / MDAC2 a little over a month ago - Dec 21... I should have first code full completed in 2 weeks or so.
I have current code supporting upto 768KHz which is the max sample rate the FDAC / MDAC2 is designed to support. Being new to FPGA's part of the learning curve has been to work around the synthases and layout tools to maintain the required clock speed.
The FDAC / MDAC2 will feature an upgradable modulator / filter PCB like the Original DaCapo, the first filter will include the HDCD PMD200 as a reference digital filter (user selectable between my own design or the "reference" HDCD filter).
The PMD200 supports upto 192KHz, sample rates beyond 192KHz will be supported by my own FPGA algorithms.
Once I have the code completed and working on the FPGA developmental board I look forward to designing the Modulators PCB and wiring up inplace of the AK4137's used in the DevDAC PCB.
Friday I received an Email from AKM where they say that the AM4137 will be available from March 2022! so I'm VERY happy I have made such progress with the FPGA replacement.
I REALLY look forward to listening to the results soon,,,

you must be joking.. we still have to wait 50 years?
Could you please start taking your medication again and stop the inane rambling. "The Boys" are at it again!

You are not a sound quality evaluation device
If you look over at the measurements on ASR you will see that measurements for coax and/or toslink are often givne as well as usb. Amir has explained that the latest AKM chips seem not to have a resampler [which I take to mean ASRC or at least not such good ASRC] which tends to give them worse measured Coax/toslink performance -see
https://www.audiosciencereview.com/forum/index.php?threads/topping-d70s-mqa-review-dac.18728/
So if you are looking for best non-usb performance from a dac which is essentially just implementing the dac chip rather than adding anything much, better go for an ESS chip.
Shame that not many dacs have the useful functionality of an mdac in slaving to a cd transport [whoops sorry Tony, I had not read your comment upthread about not posting about dac chips]

I’m taking all my medication. Sadly it’s not going to make my MDAC2 get delivered I. The foreseeable future.
Tell you what, let’s have a bet. £500 it’s not delivered before 2022.

“Before presenting the planned project schedule, it is important to stress that any timeframes given are only our best estimates and cannot be relied upon completely. We are undertaking development of the very best DAC possible and that is the primary goal which necessarily takes precedence to meeting any self-inflicted deadlines. After all what good is a DAC delivered on time, but knowingly crippled? That said, let’s look at the milestones and projected timeframes and the related instalment payment schedule.”
That’s from 2017. The project timeframes have been removed.

Its allmost all saved for posterity in archive.org... Someone had the foresight to add it to the register many many years ago and its been fully indexed.

During the time elapsed I’ve welcomed a granddaughter into the world whom I am currently teaching reasonably complex maths to. I’ve retired from work (I had no thought of retirement at the point all this started), I’ve lost two of my closest friends to cancer and my football club has been promoted and relegated 4 times. We’ve endured a global pandemic, one which I’m reasonably confident will be a thing of the past well before the project in question bears fruit. Who’d have thought??
