We will se the results within a few month.

  Thank you. After testing ES9018 and another ES9018K2M diyinhk boards, the next logical step would be to give a chance to the AK4495SEQ or AK4490EQ. They seems to be the best DAC chips of the delta-sigma world. Or continue with the tempting Soekris distcrete R2R DAC. But I have changed my...

You are rigth, google search like "LT3042 diyinhk" directed me to another page of the topic. Thank you for the link. I also like the sound of Cree schottkies as diode bridge, but  I used them in high voltage tube circuit. In low voltage applications old Motorola MBR ones are also appropriate...

You mean that you have this DIYINHK PSU, and sonically looks fine?

I have got the info from a card owner in private msg. Before purchasing this board with tempting parameters (the chip at least), I'm curious if anybody can confirm or confute? Is it a unique or a common feature of the boards?

I have got a warning not using the diyinhk LT3032 board:   "i would not recommend you diyinhk LT3042 0.8uV. After researching was revealed that it has congenital defect made by diyinhk. The high freq noise on Mhz area is spreading around everything and no possibility to fix it without removing...

I just have a currently  unused 5V/2A on the toroid. Thanks wisnon.

Does anyone have Bendix 5R4WGB (potato masher) datasheet? I have a Tungsol 5R4WGB datasheet only, but as far as I know the Bendix has 5V / 3A heater instead of the normal  5V / 2A heater. Maybe other differencies also exist.

It was interesting to read. Wisnon, thank you the lot of information, you have helped a lot.

What an interesting coincidence. One small complaint I just had the little sound stage in relation to the Amber. Perhaps a better diode that will help a bit? I know, they are different performer, but why not?

I live in Europe. Lukasz asked, but not answered yet.

Thanks to this forum and the google search engine I slowly familiarize myself with the tubes of this DAC. But the stickters are still forbid me to  actually roll them :(.

I see. For now, I look forward Lukasz response, which diode he suggest.

  Thanks. I'm just connecting Lukas asking of the upgrade possibilities. I will ask stickers too. And what is actually "the latest big bottle rectifier" ?

Sorry, I have no "previous" DAC to compare it directly. This is my first USB DAC. I have analog inputs to compare, turntable and tuner.   But you gave me an idea. I will compare the difference between a local radio station using an FM tuner and the same station streamed from the internet.
