On report again.
Such is life. (Ned Kelly).
Anyhow I'm in the process of having a listen to Diretta with Audiolinux and Gentooplayer both with Windows Asio or Linux/Alsa running Roonserver.
Ian's DAC/PI4 4GB.
TBH the more I read then info on the Diretta Site the more I was thinking Jplay for Linux. Same small fast buffer network Ideas . Marcin and Josef have been doing such things from way back but for me the hungry 2 PC approach was something I wanted to escape from. Audiolinux and Gentoo Targets fit my current thinking quite nicely and with this old fogey only listening to 16bit makes Dirreta free to try out on both.
Gentoo has a free software try out Audiolinux not but I ended up paying for both anyway. I'd used both as freeware back in the day so not a total novice. and both improved quite a bit in that time. set up is now much simpler even for the ssh adverse with Web GUI for both. Still like ssh myself.
It's been great fun and a real ear opener.
Time for heresy No 3 🥷
I never really liked RAAT that much and preferred Squeezelite SQ wise for it's fuller sound and easy top end.
Both sound really good and have decent Web GUI which helps setup quite a bit. Audiolinux requires just a little more effort (just config file work) but even I managed to blunder my way through it.
But IMHO it's Diretta that really shines and maybe Gives ROON the sound to match it's lovely interface but don't quote me on that ROON forum wise.
I have Audiolinux Running on a 4G PI4 Ian DAC as target Ramsystem enabled with just pretty much standard set up and no kernel exploration
I then had a go with the Diretta Asio Driver|Roonserver on Windows first.
Mmm nice.
Next up Gentoo/Roonserver/Diretta host/ Alsa No Ramsystem . Alsa sounds noticeably better to my ears and in my setup (Stevie) with a fuller more alive and dynamic sound.
But that's just to my ears and IMHO.
I've kind of settled on the above Host/Target setup which I'm more than happy with SQ wise.
So Wladimir/badd99 worth the Cash?
Yup for me money well spent so thanks for the nudge.
Anyone wants to help squeeze more out.
I'm all ears.

Nice work with the Lan cables BTW and many thanks.
Second thanks likewise for sharing.

@WladimirMXP On this forum you talk about using Diretta WiFI...Same SQ? Did you end up making that video? I still didn't go down the Diretta rabbit hole but I know that if I can have same SQ with wifi ease of use that's very interesting. Keep us posted 😉

@pkonstantinidis @Ras Dan the Protodac does not need any amplification that is the beauty of it I have 2 systems 1 Protdac and 1 Ian dual mono dac/Opa861 and they are exactly the same level output I would also check the IV resistors on the Protodac mine are 420 each 🙂 or perhaps a defective dac chip.
@Gabster 2000 And which system do you prefer in terms of sound quality? The Protodac or the Ian Canada dual mono DAC + OPA861?

@pkonstantinidis I prefer Ian Canada dual mono DAC + OPA861 for sure , But for the money the Protodac is a steal and so easy to power and will sound good with a cheap power supply. And there is a large chip supply still.
@Gabster 2000 I am thinking of placing a ProtoDAC on top of my FifoPi Q7. But it is unclear to me whether the ProtoDAC can benefit through the GPIO from the advanced re-clocking of the FifoPi Q7. Thoughts, please?
Hey, actually for my Diretta stream I'm using two WiFi networks. One for sending the stream, then goes through a 2x reclock phase and gets back to my primary chain via another WiFi. Still better, sounds more "Hi-Res" / more information coming to me, than keeping it just on my LAN. But it's not that simple, the actual network architecture and WiFi network settings matter a lot.
I know I'm late with that video (a lot), I'm just literally flooded with new ideas, materials and approaches how to "perfectionalize" my innovative streamer build and LAN cables. In the meantime, at least I've further expanded my understanding of the underlying principles, why I'm hearing what I'm hearing. Good news is that I've at least started to write the script for this upcoming video.
Hello Greece,
I will take a wild guess. The protodac is lower in quality than the Canadian dac. I have used the Curcio dac with the Philips chip and tube circuitry which was a nice sounding dac. But still there was room for improvement. Could well be that Gabsters circuit with the Philips chip could work very well with the Tent shunt after all Mister Tent did work at Philips but i wonder where all these chips come from when i bought mine a few decades they were already getting expensive.
Of course with the Philips you have a bit more possibilities to change the sound because there are some components to exchange.
The only way to really know is arrange a meeting to compare some things.
Take a look how my fellow countryman does his research

Now that is interesting, Who wouldn't want that A8 quiet and sweet ride! Thanks for sharing, pretty interesting blog.
Edit: Stupid me, didn't realize it was Doede's blog!!
It is a fresh, progressive, and explorative idea! A precious contribution to this thread.
Compare how different "things" sound...
Almost 12,000 posts and nobody thought of it before?
Hello Ian,going to use triple pairs for 5V. Charge with 5,5 A,can you guide me which component to changeUcPure double configuration
A friend of mine was crazy. He asked me to build a UcPure II with two pairs of 3000F ultracapacitors in parallel. That’s really awesome.
With this configuration, the pure time will be doubled for sure, but the most important thing is that the ESR will be just the half. So it means that the performance will be improved even more.
During my test, I connected this UcPure double to a StationPi Pro (my ES9038Q2M Dual Mono II DAC) to provide the 5V power supply for RPi. I was surprised to find that the sound quality got improved! That makes me listen to a lot of music files again and again with new discoveries. But with the built-in isolator on FifoPi Q7, why can a better RPi power supply still improve sound quality? I think the reason could be that, during my phase noise measurement on my SC-Pure, I’ve found that the environment EMI noise can degrade the clock phase noise performance if the phase noise is already lower than a certain level, especially some noisy devices within 1 meter range of the clock. A RPi could be the case. But an ultra-low ESR UcPure double power supply can be a great help to suppress that EMI noise.
If there is anybody who has had similar testing or experience, please let me know for the update.
Charging current was increased to 4.5A from the default 3.5A. And also, it’s better to enable the SYNC charging function of the UcPure II.
BTW, using a 12V/3.5-5A AC input would be better than the 18.5V laptop adapter to eliminate the EMI noise of a SMPS.

Hello Sweden,
If i am right the ucpure circuit gives you the option between a rather big current and a limited current. I thought it was recommend in the manual to go for the lower current. The initial charging will take longer with a bigger number of caps in parallel but once charging is done you will need a tiny current to get them recharged again.
If there are 3 pairs of caps joined in parallel will you charge them at the one in the middle and connect the load in the centre too.
There have been test with big caps in parallel connected by copper bars. In a crc network with one cap resistor and a pair of identical caps the best results were achieved by connecting the R in the middle of the copper bar and connect the wire to the circuit board as well.
Of course once the charging is done with ultracaps it will be different. It could be that giving each pair a set of wires to the boards could sound different. Ian could test this!!

Hello,
First goal is to have to get these stacks working.
The people who succeeded in getting things to works should share ideas how to improve things with other people having working stacks.
The people who are struggling should try asking advice here and hope some kind of Harry Potter will help them out.
Or a WELL written manual should be published. Writing instructions is almost an art. Soon they will be written with AI and then it will be chaos allover.
Greetings, Eduard
If people are stuck then head over to @Gabster 2000 youtube channel and superb videos are there for step by step tutorials.
The manuals are well written and Ian welcomes constructive feedback as I have provided a few times.
