Thank you Greg for your comments (I must say that you posts are, in general, very intresting and helpful) as some are giving ideas to further investigations.
Unfortunately I’m working abroad and I could not put together even a basic workshop bench. Due to this I my DIY activities are reduced to finished boards assembly (LEGO training ) and simple soldering eventually.
Also my free time is very very limited (several hours during the weekend). Despite that I read a lot in short chunks every time when i have a short break. On the positive side I found many intresting information, on the negative side all this information come in random small chunks and after a while is difficult to recall them exactly .
I will try to look deeper in the possbility of using 502DAC Pro in slave mode with reclocking provided by other board for the pure digital part of it.

The I2S HDMI output is an old idea to implement. I know about an AudioGD module and was another one that, unfortunately, was always out of stock when I was trying to buy. The Ian’s one is a really good news even if will come a bit later. As far as I understand these could be directly connected to the Ian’s IsolatorPi or FiFoPi boards by ufl connectors on the boards. If working will be a useful digital out option for people having external DACs with I2S input (PSAudio, HoloSpring, Gustard ....)

Regarding the new Ian’s GB offer there is only one problem... is offering too many goodies. Most of them tempting.

At this moment I will definitely have an IsolatorPi II, even if I already have the first version that according to some posts from SBAF could work with 502DAC Pro by removing one resitor to GPIO 31 pin. The Isolator Pi I or II boards I will use either for the 502Dac Pro setups or when I want to use the Odroid C2 instead of RPi in any setup.
Then I am also taken the FiFo Pi for the complete player solution with Ian’s Dac board and I/V stage and maybe to ivestigate further the path that wou sugested (502Dac in slave mode).
Then are the option for Dac boards and I/V Stages. Here I’m now with the Dual ES9038 and std Opamp I/V stage but still under investigation. I’m mainly using my speaker system (Cayin A88T mkII amp + Tannoy XT8F speakers) that has SE inputs but for headphones I have amps with SE and BAL inputs . This doesn’t make the decision process Easier.
Even is my system is probably not the most “audiophile grade” I’m trying to make my decisions based on a good research (for technical info), good quality at reasonable prices and most important a great deal of common sense. In this regards Ian’s offering clicks all the correct boxes.

On the power supply I’m the most undecided at the moment. Not because I’m unsure about the quality of the power supply but because I’m equally intrested in the ultracapacitor version. Since the price is relatively high I’m not sure if I could have both.

You are right with the Rpi shutdown sequence. To be honest I did it also many times. Anyhow my players are usually running continuously and I shutdown them once in a wile for an update or for some tests. In case of on/off them daily also the risk of sdcard corruption probably increase. Anyhow as I said not a big issue.

Thank you again for you suggestions.

Hi Ian,

is there any manual I can refer to bypass those regulators?

Thank you
Andrea

Andrea,

Check Ian's FiFoPi draft manual for those details.

Greg,

thanks for the info, but I'm not interested on FifoPi, I'm planning to use FIFO II, Dual clock board with external oscillators and I2S to PCM board.

Ian asynchronous I2S and S/PDIF FIFO KIT group buy
@andrea_mori, sorry, I can't help you on the FIFO II, I don't have one here nor am I familiar with the documentation.

@lucser, thanks for the kind words on my response. Some just seem to think they are too long!

Sorry to hear your current situation limits your DIY efforts and access to your shop. Having been in that situation before, I can appreciate how frustrating that can be. Being able to spend some bench time at least every week helps me stay sane in these trying times!

On the I2S-over-HDMI, there's a fellow in Audiophile Style under the handle of tapatrick who has done this using the Audiophonics board, though not without some frustrations. You might search for his posts on that there if you haven't seen them already.

Your plan on Ian's GB items sounds good. On the output stage for his DACs, Ian has several other I/V stages in-work. I suspect he'll also offer his OPA1632-based stage during the GB, though that is just a guess on my part. He's also working on an OPA861-based stage, I have a couple of his boards that I was building this weekend. I have higher hopes for this one being a VG stage at a reasonable price. Topologically it is not dissimilar to the Twisted Pear Legato, which so far has been my favorite of their I/V stages. Of course as I mentioned you could use a really good discrete opamp like the Sparkos in his standard I/V stage, but that would be pretty expensive. AND I commented on using transformers in Ian's DAC development thread and my 'Getting the best out of the Allo Katana' thread.

On the power supply, I'm hopeful the UltraCap supply will be the better option, but I'm going ahead with one of his LiFePO4 supplies now to have it for comparison later. I have several of Ian's experimenter's boards for the UltraCap supplies and have reworking them for a different brand UltraCap in the queue for a new trial soon, I suspect that'll lift them a bit from my last trial.

Later!

Greg in Mississippi

Yes, you are right, my messages tend to be long. English being not my first language I always admire when reading the briefness of English language. Unfortunately I didn’t master this skill yet even if, when reading, looks so easy.

I’ve found your posts regarding transformers I/V stage very intresting. I also look forward for the final details of this and other versions what Ian is offering in this BG. Probably I will end up with more than one. Same probably apply for the power supply despite of the price.
Regarding the transformers it is a bit difficult for me to find a good source here in Korea (mainly due Korean language) but if they are found on Mouser or Digikey then is easier.

Thank you for the I2S adapter tip. I knew about such board on Audiophonics but different than what is offered now and when I was looked was always out of stock. I will try to find the posts for more info on the subject while waiting for Ian’s version that looks much better quality than the one on Audiophonics.
I’m truly amazed of the quality of Ian’s boards, that beside the smart engineering involved also looks very well. The wormanship is top class.

Have you listened to the Mercury? If so how does it compare to the Legato?

Thanks!

Hi Ian,

I think my question did not get answered. Could you please let me know?

Thanks
Do

Default FiFoPi + PCM board

Dear Iancanada,

From the FiFoPi draft manual one can read there is a jumper to allow I2S outputts at 16 bits or reprocessed 16 x2= 32 bits depth outputt.

I read somewhere than the FiFo II board and MC FiFo board already increased all I2S signal in 32 bits at their outputts.

How must the FiFoPi be setuped to feed your PCM board please ? Or does it mean FiFoPi is directly also proof for 16 to 24 old PCM chips without your PCM boards by playing with the bit depth jumper ?

Or does the FiFoPi has an I2S outputt justified just for the modern chips like the ESS or AK dac chips only (without being able to be conned to the PCM board) and in that case you advice me more to jump in the FiFO II or MC for my old PCM dac chips?

I don't understand to what refer your manual formula "all in one PCM/DSD/Dop". I understand it can read PCM format but is it able also to feed directly PCM chips (so without PCM boards)

I apologize for my poor understanding despite having read your manuals.

Edit : How much memory buffering is allowed (same as MC Fifo or same as FiFO II... or different)
