Turbon,
You are so wrong.
We made all of this from pure pleasure as many people on DIY audio.
We did not get rich from a product we have already invested far much money and time than we won so far.
We offer a DIY product and I also expect people understand this is a Do It Yourself. Some things always can be improved, even when the product is perfect, there are many other things like communication support etc.
We are here from pure pleasure because we share same hobby as this great community.
We have designed this product with joy and we hope will bring same joy to others.
If something is not working as you expect, fix it and help this project to grow.
We have shared everything on this project: lot of documentation, schematics, drawings and source for parts. We even designed and produced parts from scratch.
You can share your experience as well. Good or bad will help this project grow, but act like a DIY-er not a frustrated customer.
Here is pure DIY for others are high-end stores where you may get "pristine" and "perfect" parts.
We are not here for such dialogue.
I will send to you another CD puck who have lower tolerances.
Regards,
Tibi

Enough said about this. Never mind the puck - somone else might need it. 🙂
What is the next mod?

What I mean is how to avoid this :
I have not found any info on the manufacturer's site petra-toroid.ro . Should I connect any brown to any black on primary in order to be "inphase" for 220V?
For 220 V / 230 V brown and black from middle must be connected together .What I mean is how to avoid this :

Well said, Tibi - It's DIYer's like yourself that help us less experienced folks (me 😀) participate in this great hobby.
i have now implemented 4 caps of the wow effect and it made a big difference. i previously didn't replace the vref cap. i used arcotronics in this position as recommended. i must say that with all the 4 caps now installed, the highs got silkier, soundstage is deeper, blacker background.. thanks guys.. now waiting for 100pf silver mica for the trimmer as suggested bu tibi.

Transformers are custom made for this project. You'll not get any info on factory site.
Please follow Danzup drawing. You need to connect primary in series, not parallel as in your drawing.
See also attached picture for 220Vac.

Thank you, I wanted to be sure to connect it in series and avoid parallel.
Thank you again 🙂
Hi Turbon,
At first I go a long way with you with your remarks but later on the huge DIY factor crept in and lets face it ...the costs are kept to a pleasant minimum (although I personally do not care about the costs) as well forcing us to be more tolerant to our hobby.
The best thing.( ..even better then Tibi suggested by sending a more tolerant puck) is to slightly sand the puck pin by hand...quite easy just a bit of time consuming.
This will result in a fit which matches your cd platform best.

Thanks Erik - I did as you prescribed and it is better but needs another go with the sandpaper.
Yes, this is DIY so I have made peace with Tibi 🙂

Tibi,
I folowed your recomendations, checked everything again, paying particular attention to the flat cable and... it works fine! Thank you Tibi.
On an other subject, I am interested in adding a balanced AES/EBU output. My dac can accept such an input and my audiophile friends too.
This could be an interesting experience and be usefull to other members.
What would you suggest I do. I tought about a transformer, of course, but other solutions could be more adequate.
Not knowing the outup characteristcs of the LC78601, I hesitate to put anything accross it. What would you recommend?

Just today I was thinking about the same thing.
Very interested to see how it could be done. Perhaps even XLR and Coax both.
Very interested to see how it could be done. Perhaps even XLR and Coax both.
This can be done several ways.
One is to use a current repeater, like one transistor/tube with spdif transformed in emitor/cathode.
Another one is to make a current buffer with a bunch of 74HC04 gates and feed s/pdif transformer through a capacitor.
In any case you need a good s/pdif transformer. Audio-note make some great ones.
I'll draw and post few simple schematics.
Now my advice is that in case you use a simple cable between transport and dac this must be at least 1.5m . The reason is due reflections and was several times mentioned on this forum. At this length I prefer RCA.
Don't underestimate the importance of s/pdif cable. Use highest quality you ca afford.
A poor quality s/pdif cable is acting like a delay line adding lot of jitter.

Tibi,
two questions:
1. what sholud be the foil thickness
2. how to stick the foil/plate to the ICs assuming it's is not selfadhesive
thanks,
Andy
Hi.
Have anyone tested the Mundorf Supreme Silver/Gold Oil instead of the Mundorf EVO Silver/Gold Oil at C8? Othervise all components are ordered to upgrade my transport/board. Hope they arrive quickly 🙂

1. 0.1 -03 mm even thicker should be OK.
I use 3M copper shielding tape with non conductive adhesive.
The code on my tape is 3m 1181 1142-09
2. using this http://www.diyaudio.com/forums/digi...kii-black-builders-thread-20.html#post3947245

Yessss..
It was a nice sounding cap but not as nice as the Alexander Duelund or the DIY of Zey (sounded simular to eachother) but the best hands down was the CAST Duelund....but price might be over the top for most of the builders.
I tested about ten caps in the C906 (C8) position
