Ian asynchronous I2S and S/PDIF FIFO KIT group buy

[VenusFly]

Hi Jorge,

parts and connections:

- I2S receiver to Ian's FIFO (you can also use Teleporter from Twisted Pear)
- Ian's stuff (FIFO buffer + single clock board + I2S to PCM) to Red Baron DAC with Rhopoint IV resistor (you can also use Ryanj board)
- TWRPS-pp regulator as PS for Ian's stuff (The Well Regulated Power Supply)
- Master clock for Ian's FIFO reclock (TWTMC-D, TWTMC-D&D, TWTMC-OVN, Sc-Cut crystal at 11.2896 MHz, TWRPS-pp micro regulators)
The Well Tempered Master Clock - Building a low phase noise/jitter crystal oscillator
The Well Regulated Power Supply
- Salas shunt regulators as PS for Red Baron
- Red Baron to Aikido with 4 x 6N23P (you can also use your IV converter)

Hope this helps.
Do not esitate to contact me if you have any questions.

Andrea

This post doesn't tell you at all where or how the psu boards were acquired. Were these made by yourself or is there a place where I can buy them? The only links that are show are of a development thread that stopped in 2012.

It also doesn't detail what the boards are called and the jpgs are too low for me to be able to read the names written on the boards.

Its extremely confusing for a newbie to diyaudio.

- AIKIDO All One 9 pin: AIKIDO tube buffer with 4 x 6N23P, PCB and components available, fed from Red Baron DAC (http://glass-ware.stores.yahoo.net/aialture.html)


As soon as I find the time I will start a dedicated thread to describe in detail, with parts, BOM, source and so on, the entire audio system I have built for a friend, that include the TDA1541A DAC (some pics attached).

Thanks Andrea, this post is useful!

 

[VenusFly]

Thanks too! Helped me a lot!

- TWRPS-pp: 6VDC 500mA linear regulator, power supply for Ian's stuff, I could arrange a GB for the bare PCB, you can also use Salas shunt (The Well Regulated Power Supply)

I would be very interested in a groupbuy.

I got the isolator and the DSD DOP decoder from IAN back in July, but I was able to experiment only recently, with and RPI2 and IQaudIO Pi-Dac+. Even if I'm using a relatively low cost LPS I bought on ebay for 60$ the end result is very very good.
However my projects are taking a different direction, so if somebody is interested in the isolator and DOP, just send me a message.
I hope this is not against the forum rules...

Hi to all,

I wanted to share my ΛΓienStreamer project with you.

This streamer is based on:
RPI + PCP + IsolatorPI + FIFO II + ISOLATOR + DUALXO II + 8x AGD DA-M1

DA-M1 modules are in Push-Pull and balanced, thus 4 per channel.
Modules are powered per set of two. This means, in total 4x 3.3VA + 4x 3.3VD + 4x 1.8VD

IsolatorPI, FIFO II and DUALXO II board are powered with seperate 5V supply, and TCXO's are separately powered with 3.3V

The used psu's are UltraCap-based power supplies which have NO noise, can deliver very high currents and do have very low internal resistance.

ΛΓienStreamer uses 16 psu's in total, consisting of 32 UltraCap banks, with a total of 120F (which is 120.000.000 uF)

Hi All,

Newbie here. If I want to add the FIFO and reclocker between Amanero USB-to-I2S and Soekris DAM1021 should I get the McFIFO and McDualXO board? Any other accessories (cables, etc.) that I should get?

Have anyone tried the FIFO/Reclocker between Amanero and Soekris?

Thanks.

Hi,

I placed an order with Ian more than a week ago and he has not answered. It is strange, because other times it has been fast in cotestar, it does not answer private messages either. Does anyone know if something happens? I hope everything is fine for Ian.

regards

Hi,

I'm here, I'm fine .

When did you send email to me? Can you please sent it again? Some times I got too many emails. Might be flagged wrong as read.

Sorry for my absence.I'm working on something interesting.

Oh man, that looks tempting!

 

[Jjazz]

Hi Ian!

I'm very happy that you're doing well and working on new projects! (I2s dac?)


I have resent my order. Can you confirm if you have received it?

Hi Ian. Is your new project a refinement of previous arduino based FiFo controller or totally new design? Looks cool either way !
Best, Peter

Yes, this is totally new design based on 32bit ARM cortex processor. It has everything live Fs monitoring, remote control, rotary encoder, oled screen, fw upgrade and many more. It will support ES9018K2M, ES9028Q2M, ES9038Q2M with automatically detection. SYNC and ASRC mode switching, DPLL on/off and anything else.

I'll challenge zero bandwidth with it later when I get my ES9028Q2M PCB.

super cool Ian, looking forward to seeing developments

cheers

 

[maessen]

Yes sounds very interesting.

It will be very interesting to follow your developments.

Great work Ian!

Hi,

I am currently trying to figure out how to further reduce jitter in my DACs (one with Wolfson WM8741 and one with PCM1704. I would like to go for I2S input and Ian's reclocker. Also because they have a rubidium clock.

I have two questions:
- Does the reclocker work without a PI (just I2S-input/output, clock and voltage)?
- What's that slave mode the DAC has to be set to? I am not sure if older DACs like mine support it.

 

[Dimdim]

- Yes, Ian's reclocker is basically I2S-in, I2S-out.
- Most if not all older dacs are running in "slave mode" anyway.

Yes, FIFO works with WM8704 and PCM1704(if you have a DIF in front of it, or driver circuit ) directly. You can also get PCM1704 more improved if you drive it with a PCM board after FIFO.

Talking about rubidium clocks, may be they are not as good as you thought for audio applications. But I could be wrong.

I bought two of them years ago, but I'm not very happy with the result. The sound quality was not as good as other low phase noise XOs, such as CCHD957 or even Si570.

Rubidium clocks have super good long term stability and perfect accuracy, but not really at the phase noise.

I think the reason is that, on the phase noise plot, I found there are a some high spurs in the middle range. The attached plot is for a thousand $ rubidium clock.
That means the jitter level could be high at some fixed frequency offset.
PRS10 - Rubidium Frequency Standard

But the good thing is that most of them are pretty decent at build quality

Good weekend,
Ian
