Whooohoooo! I have my S03 up and running with my very own diy adaptors. Hopefully the adaptors from Acko shall made it here before Chirstmas?!?
Right now I still have one more tweak with the SuperRegulators SSR-03 from Per-Anders but so far Me like very much!!!@Acko- can S03 accept negative voltage together with positive voltage at various voltage inputs?
S03 has added the extreme purity to the sound, everything sounding so refined, and obviously dead quieted dark background. From here, if I may say my digital frontend is nothing but completed! Well, unless R2R is coming out soon.
Thanks Acko for this beautiful piece of work, S03 that is!
An externally hosted image should be here but it was not working when we last tested it.
Many thanks for your efforts and feedback!
What was proposed as a concept has become a proven reality now!
Still sinking in and looking for ways to tweak this further. Real inspiration for future developments. Well done!
Apart from the reclocker action, the S03 outputs have fairly good drive to rev up to many floors of your high rise tower
May be not all the way to the top but better than connecting naked signals direct from source previously.
Could you adapt one of Acko's little ufl boards (DDAC, BBB, etc) to provide ufl connections to a TP COD dac? I've not checked in detail but it looks like it might be feasible?
Ray
Sorry I got lost in the acronyms for the boards this is what I need.
Giulio: BBB - UFL (1x) + BIII - UFL (1x) both with UFL mounted
IanS1: DDDAC-UFL (with UFL mounted) X2
Myint67 DDDAC -UFL (with Ufl mounted )x2
Stijn001: DDDAC-UFL (with Uf.L.'s mounted) 2x
Dwjames: DDDAC-UFL (with Uf.L.'s mounted) 1x
Thanks
Chanh,
Hope you have received the boards by now.
Just realised. while checking carefully, there is a pitch error with the DDDCA-UFL boards - 2mm instead of 2.54mm
I will to redo your boards for replacement but will take another 2 weeks to sort out.
Shipment to others have also been recalled!
Really sorry for the issues
Hi Acko,
Your package still has not arrived. It's 22:47 in the evening of 16th Dec 2014.
I think it fairs to say that I was not mean to have these adaptors!?!? If you do not mind and also per our corresponding email, grateful for the refund here on for I to move on!
I still interested in the SuperCape whenever is available. Will make necessary payment when the time comes.
Regards,
Chanh

There is no doubt this S03 has lifted the sound from my setup, despite I have exhausted all funding to ensure only the best are in placed within my system synergy. By that I meant of the following;Many thanks for your efforts and feedback!

Dedicated an audio 20A powerline from front power meter direct to audio room. This line is downstream into AU$7,000 PS Audio Perfecwave Power Plant P10 which is supplying all my Tubes/Vavles mono blocks poweramps and CJ preamp. It is also powered DAC tower and your S03. The rest of my digital front, laptop, USB-HDD, audio router, switch are on a seperate 10A powerline which downstream to a 5kVA balance isolated transformer which is then supplying all frontend CA through applicable linear power supplies. Aircond and room lighting are each on a dedicated line of its own to mitigate noises!
With the above, S03 still provides a noticeable improvement to the sound. My next upgrade is the $750 Pulsar Clock. Do you do this upgrade on my existing S03?
Cheers.

The biggest difference is that we are (and have been since we started the project) working with Miero, so his software and our hardware are being designed collaboratively. This has many benefits, chief of which is that there is no guesswork, and that we can get changes made as needed.
I would love to post more details, as we generally like to share our work with the DIY community (schematics, etc), but I think it's clear that some people think it's cool to copy ideas commercially, so we need to keep some things secret for now
I know it sounds like sour grapes, but, it is what it is.

Some other people think it's a good idea that DIY community contribute ideas to improve the result. Thus, what was to be a Raspberry cape, ultimately will be a BBB cape.
But the really important thing is to have a cape before the BBB is discontinued.
Regards
Isn't Miero's driver open sourced? If an open source driver supports external clocking and Miero announces in his driver thread that he killed a BBB by shutting things off in the wrong order, I would assume the development of external clock boards switched by the driver and a way to prevent the BBB from being killed by improper shutting off would follow? I would expect several people to implement solutions to both of these problems.

S03 is pre-existing product meant to interface with just about any digital transport whatever you want to call it or do to hide the concepts. Ultimately, signals of the BBB come out somewhere just like any other transports and that is what is being used by S03. I do not see much being revealed by you from the beginning, so it has been a secret all along. Only Miero has gone ahead and made the BBB-botic interface public and I have seen others tapping into these signals without you raising concerns - open system, I believe.
It will be interesting to see what the internal design of your cape etc, will look like, so we will know who is copying whom?
Sorry Brian, but you need to get your facts straight. Nobody copied anybody/anything judging by the threads, if anything Acko was there first. Acko developed the isolating/reclocking boards already before anybody in your thread even started discussing a reclocking board, initially for the Amanero which (logically) evolved into a generic board.
Miero's driver merely enables the BBB I2S output, which opens up a whole variety of options, not just the possible "future" TP cape. I never read Miero's driver was proprietary or licensed to you. At least he didn't mention this at any time. Even he tested and collaborated with others in it's development & it's now incorporated into Volumio and Runeaudio.., which are both published under "GNU GENERAL PUBLIC LICENSE"
If I remember correctly Palmito was the first to work out how to use the Rpi with the S03 and that discovery lead to the logical way to using other IS2 sources like the BBB when Miero's driver became available.
I for one have been quite frustrated about the TP cape taking this long to develop, you guys have been making promises for almost a year now and nothing to show for yet.
This is I believe why several people have jumped off of the fence and have embraced the S03.
And besides that, Acko has been very forth coming in sharing information and helping the community with develop, in the spirit of DIY, were as the TB Cape is still shrouded in mystery.

Miero's Botic driver is open sourced, and all are welcome to use it, as will be the schematics of our cape, once released.
All I said was in answer to the question was:
a) Botic has been developed in conjunction with our cape from the start, so we benefit from that back and forth with him, and vice versa.
b) all details of our cape will public, like most of our other stuff, but we want to hold back the details for the moment, because many of our ideas are copied for commercial purposes.

You're kidding, right Brian! Disrespecting Acko in this way on his own thread doesn't shine a good light on you.
Firstly, miero has been true to the Linux open source ethos and exposed all the relevant information in the public domain so there is no Twisted Pear differentiation in that respect and certainly no guesswork required to use a BBB with miero's distribution. In fact miero has spoken of his ambition to get his work incorporated into standard Linux kernels so there seems little basis for trumpeting some sort of TPA 'advantage'.
http://www.diyaudio.com/forums/twisted-pear/258254-support-botic-linux-driver-31.html#post4145642
Read your own TPA 'Open embedded appliance' thread and you'll see that your project started with RPi and you initially looked to hookup with the developers of Rune Audio and Volumio; it was later that the advantages of the BBB were identified and miero came on board.
The name of your project became 'botic', a name miero's distro retains even though, after stringing people along for many months TPA has killed off the botic in favour of new boards that appear to be heavily influenced by Acko's own developments; inconvenient though it may be but Acko's SO3 board came first. Who's copying who?
It was the unending delays to the botic that influenced me to look elsewhere and ultimately purchase an SO3, along with the great support and responsiveness of Acko - a good decision apparently.
So yes Brian, it would seem to be what it is, sour grapes on your part that you're playing catch up.
Awesome setup you have there!
I am still analysing your results but the benefits appear to point to the jitter reduction of the re-clocking action as posted here
What surprised me is the noticeable improvement in PCM1794 DAC that is claimed to be less prone to clock jitter compared to ESS DACs (R-2R vs SD thing)
It will be interesting to see if the downstream action of the re-clocker can completely mitigate the effects of upstream instabilities like power supplies or network issues. e.g. will streaming from network provide the same qualities as direct from local disk? I remember you posting something related here ->
And then there is this Master Clock on the S03. Lots of airplay about isolation and GHz flip-flops but at the end everything gets referenced to this clock as explained here ->
So, yes, this "big blue thing" on S03 module is the elephant in the room and this is where I reckon we should target next for upgrades or improvements. Pulsar Clock and similar OXCOs are good candidates but I am waiting for a few more clocks types to compare and then advise.
Your setup is fine w.rt. EMI from BBB.
I am thinking more along the lines of an "acoustic suspension" as shown, given there is a sensitive clock on board as explained in my previous post. So will prefer a horizontal setup and connection using flexi cables will put the S03 Clock into the 'swing of things'

I like the "suspension" idea!
Definitely agree on both these points, I think the waiting is frustrating a lot of people by the look of the thread.

I have a AKL-AMN-S03 board that looks a bit different to the one pictured, is it still good to do the BBB setup with the Supercape once its ready or do I need the latest S03?
