Yes, I also was confirming that P1 is not using R2R, but Multibit DAC
So, the project based on AD1862 is closed?
Well, its more or less to be expected.

I would totally buy an AD1862 dap! Analog Devices is my favorite IC company, and a modern R2R dap would be way cool.
What's the deal with the T1 amp? Is that being released also or was just a prototype for A1?
Keep us informed of when the P1 availability comes around for international buyers please @tjstyle.
I would like to buy one too when they're available.......

Dream on, my friend. I will gladly join too
Unfortunately, we will never see it in production as a serial DAP simply because: 1) chips are obsolete; 2) most likely, it will be a huge brick . As for creating such individually, I think it's possible but it will cost too much for one person to get one.
Still, there are some good chips in production like AD1851, AD1856 but I doubt somebody will bother trying implement it in a DAP or even portable DAC/AMP. Everybody is fine with delta-sigma results
T1 is Nutube (Korg & Noritake) based audio amplifier, still on development.
The problem to use AD18xx DAC is the total unit dimension will be huge, I still not confidence to make due portability reason.
How big would AD18xx DAP become? I have a few larger "brick" DAP's with dual PCB's, and I love them, as long is it is less than 1.5" thick I'm fine with it
Hypothetically, I think it will be at least the size of HM-801. It's well-known R2R dap besides Hifi E.T. MA9 using mid grade chips PCM 1704. Too bad they stopped producing 801.

HM801 size is perfectly manageable, I wasn't a huge fan of the circuit design though, I had a chance to buy a brand new one on clearance at less than half price and still decided not to. I nearly bought the MA9, but the issue for me was it would need heavy modding to bring it's digital circuit up to scratch, but both the analog circuit's were excellent though, much better than HM801's.
A huge shame a perfect R2R dap was never made. But TJ can change that!
Thick dual PCB dap's like HM901 and QA360 still have a decent enough market presence.
So I encourage TJ to make a batch of DAP's with AD18XX, surely they will sell out the batch of 10! I will buy two if I have to!
Continuing to use obsolete R2R DAC chip maybe using Analog Device or Burr Brown Chip, but need to make sure the parts is easily to get.
