Is there a modern board solution of good quality for building your own DAC based on these chips as outlined in the Lampucera articles? Thanks,
George

I am referring to the Polish Lampizator dude online that advocates a tube output stage for a DAC that later looked at the Cirrus CS 4397/CS8416 evaluation board as a high quality value DAC giving it high marks and calling it the Lampucera. At one time this board(s) were available on ebay but the only thing listed now doesn't look anything like these original eval boards:

The DAC guys will step in. All i know is that my CD player has CS chips and sounds good.
And that Lampizator makes some fantistical claims.

That is great sounding dac, i use it all the time. No need for tube stage.

After seeing this thread and the Iwii reviewer’s experience of this product I decided to give it a try. I would like to have a second DAC to supplement my single board DDDAC 1794. The kit arrived from HK in about 2 weeks. I strung it together on a piece of MDF to test it. The only wrinkle was that the PS cable had a 6 pin connector and the DAC board had a 7 pin socket. An email to the EBay vendor Lawrence resulted in a quick response and verified what I had already discovered by tracing the pins on the DAC board PS connector. The end pin on the connector did not seem to have any connection. You can see the resulting connection method in the photo below. I heatshrinked the pin to help prevent mistakes in the future. I also replaced the NE5532 with an LM4562 which I had on hand.
Sound was very good. I am feeding it from a Volumio based RPI4 streamer with a SPDIF board. Sorry, I can’t remember the board details. The streamer and Volumio have worked flawlessly since implemented 18 months ago and I have not even thought about its inner workings. It just works every time with an IPad or IPhone 13 as a controller. The Lampucera DAC seemed to have a very clean grit free presentation with very good bass impact and speed. It surpassed my DDDAC 1794 in this regard. I need to look at new caps for the single board DDDAC or perhaps an output stage. I streamed both 44.1 and 96k files without issues. I have only listened once to it, but I ended up spending several hours going through many tracks and being very impressed. I’m not sure where I will go from here with it. A chassis and some PS improvements for sure. Output stage? The board has a 4 pin connector on the bottom labelled with + and - l and R signals. I assume this is an easy way to tap into the balanced DAC signals. For the cost it seems like a great DIY project to me with a very nice sound signature right out of the box, or should I say right off the workbench!

May I ask where you went from here? I have purchased the kit too and adding toroidals was a bit step up. I started out using OPA2134PA and was lot looking at the tube stage at all as I had problems with white noise coming from it. I was already really impressed with the sq and yesterday I had a friend over who suggested to take out the Preamp as it might not like the hot signal from the tube stage. He was right! So now I am streaming from a Wiim Pro, using the tube stage and going into am APEX FX8 Muse edition I borrowed from another friend speakers are old but still very good ALR Number 2. I am very happy with the sound and could live with it for a very long time. Still I keep wondering what for example Jantzen Superior Z would do when added to the tube board. Any experience here?
