Indeed, for best results, you should feed your PCM63 chips in I2S with Ian's PCM boards !
It will be better than any ready made USB to I2S chips ! (the PCM board has to be feed by a master clock : Ian's clock, Andrea Mori's clock, etc... with a clean short uf-l wire)
Of course for an even better result, the clock board should be isolated from the source : so isolator + reclocking after the source to "enjoy" the most possible the sound of the PCM63 !
Of course it's not only what you have to do : particular care with power supplies and passive parts around the PCM63 to improve the result !
Look for what Painkiller made with the AD1862 little brother chips ! Layout is important as the I/V (already pointed out).
Firstly be sure your PCM are genuine and not bought on EBay China provider !

Hi, project is in the middle(too many other project) i will get back with report when I will finish it( midle of 2018 or so)
Samoloko : I just use IanCanada stuffs for it; with the PCM63 it just needs more than FIFO/reclocker + isolator + clock, the PCM board to split the data signal for each dac chip. Ian's devices are prooven more than twice ! In this case the Clock board from Ian is feeding the PCM board for the clock signal the chips will see. (there is a splitter in the PCM board for chips like the PCM 20 bits (pcm63 / ad1862) , TDA1541A (16 bits) ; AD1865 (18 bits) and even PCM1704 (24 bits)...
@ Elviukai : look forward to see it, PCM63 chips are Worthing it 🙂 . (it lacks to my personal collection ! Lucky you if genuine ones !)
goog luck

Hi, progress is much slower due speaker audio duties, but still slowly progressing.
testing each dac for 40 hours (someone said desoldring them damage unit ant it plays maximum 2 weeks) need to check this before designing PCB.
not sure if i go with single ended 24 units (total 40mA ) or 48 units total curent 80mA) which would open interesting IV conversion options. due qty they will be in multistacked pcb.

I do have a brand new PCM63 DAC from LeeHee (LeeHee XA1 Decoder) and I do have a
SONCOZ LA-QXD1 DAC as well . The "System-Chain" is :
LHY Ethernet Switch - USBridge Sig Streamer - Singxer SU2 Reclocker - LeeHee XA1 Decoder - Audio-gd 9p Amplifier - Fyne Audio F502 Loudspeaker surprisingly I can not hear a difference between PCM63 and SABRE ES9038Q2M !

Hi, nope, its only 10years have passed, and good project is like good wine.Need som time. its in the middle. but smaller "daugther" projects with 8x PCM63P-KY is finished. after working with PC and new chips DSP i must say its a big NO. i have tried new DSP FPGA based DAC and also OLD (1990-2000) and swaped dac chips and IV from one to other. only the DSP(and some glue logic) being changed. old dsp chips inspite low speed and high power consumption sounds better.
also after 18years experiments with pcm63 I must say that PCM63 is one of the hardest BB chips to make sound balanced(same goes to df1704 which is completely oposite in sonics, ery hard to make sound natural and easy/relaxed) pcm1704,1702 ad1864, pcm56 its so easy to make sound "modern" not the case with PCM63. but efforts pays off when implemented right it outperforms other chips.

uhh how much work, you're on the hump... but what do you have for daily listening? which one to give?
angle I have a project that I don't understand too well, but with the help of your forum I could manage to carry it out. at least I hope so.
I have a technics SL-P999 that I want to convert into a DAC. so completely remove the mechanical part..
he uses PCM63 chips.
I just need to figure out how to run spdif in I2s and from i2s to technics.
because he is a top dac converter. I don't know why I would build my own dac from scratch. at least for my needs it no longer needs it.

You need to work out how the parts you want to keep connect to the parts you no longer need and the nature of the data and control connections between them.
