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.

So my Amber  tube configuration is: 1. ECC81/12AT7 and ECC180/6BQ7A (Ecc88/6DJ8 equiv). 2. ECC82/12AU7 3. 6x5 GT Am I right?   I have experience in ECC82/12AU7 only. I have the following wariants: National labeled, made in USA ECC82, came with the Jadis JA30 monoblocks. Amperex ECC82...

Thanks for the information. And you are right, it's 6x5. 

I was lucky enough to find a "used" Amber DAC for sale 150 km near to my home. I'm not the guy who buy hifi without personal listening.  The "used" means it was almost one month old. It's a very new product even here in Europe. I had listened it with my Stax HP (it has an own headamp), with my...

By chance I have found a Lapizator device to sell just near the city, and the selecting my first USB DAC project ended abruptly. Good luck everybody with the Mini. I think I have to change to the Lampi topic.

You can do it surely, if you want. I wish you to develop an even better product than the micro iDSD. Thanks.

Currently I'm rather in the analogue domain. I have Kuzma Stabi turntable with Van Den Hul Colibri pickup, Clearadio disc washing machine. I also have a Marantz 10B tuner. The only digital souerce I have is an old Philips CD-304 cd player. Modified with Bendix 6900 and RCA Nuvistor tubes, Black...

Ifi, thank you for the information. But ... I have got a micro iDSD + iUSB + GEMINI for a five day trial period. And I have to say, I was not very impressed by the iDSD as a stand-alone DAC in my home stereo system. It was not especially bad, but replacing it's preamp with my system's pre, and...
