Hi Ryan,
Could you suggest a fifo project that will work well with the D3. I do not use Rpi and most input will be CD a Shigaclone Black MkII I built. Streaming is 3rd in line for me as CD and vinyl are my primary modes. Thanks for any input.

best regards,
Steve

Fantastic work! How do you like it?

I was happy enough to continue the project. I'm working on a more permanent setup to place in the living room. Well permanent...

- D3 5v by LT3042, 26v by Salas Ultrabib
- I/V 6N23P tube.

First tried a 130ohm I/V resistor but that gave a lot of hearable distortion. Lowered that to 65ohm now and thatís far better sounding. Detailed, great soundstage.

Iím testing it beside a 4 decks dddac with Cinemag 15/15b transformers.

The last one is my reference to compare dacís and most dacís canít compete with it. But... this D3 setup can come very close with itís own signature, I like it very much even it still have to run for a couple of dayís to burn in.

The setup isnít finished yet (will it ever be?) maybe some UConditioners here and there and for D3 5v a ultrabib is also an option.

So thanks Ryan for the good work!
You're welcome

Very nice setup, nice and neat too. Glad you're getting some good results! Those 22u Rubycon film caps take a little while to loosen up, so you should get even better results after 50-100hrs.

Hi Steve,

I have only had experience with Iancanada's FIFO V1 and it does a very good job. The main objective of the FIFO is to reclock with a better clock than the source, so this should be the main focus.

Hi 3kes,
Your setup is close to what I am working on getting to.
On your FiFoPi with Accusilicon clocks, what frequency's are you using with your D3?

Since you guys are trying out I/V resistors, may I recommend Shinkoh 2 watts.
The best that I've heard for TDA bested even Rhopoint .


Cheers

Anyone else working on their D3? For those of you who have boards but haven’t started, let’s get those done!

Cheers,

Greg

And its running without problems ? I thought all the time, that the TDA1541A needs the 22/24Mhz clocks...
