Looking at Digikey offers.

Hello pm325! I use six power supplies in my device. I agree that the quantity and quality of power supplies is very important to sound quality.

Could you recommend a manufacturer?

Yes, I would be interested.

I have listened to many different cards and from the available I consider the Samsung Pro Plus to be the best. I haven't heard of SLC myself, but I read a lot of rave reviews. The Philips RC5 CD protocol is used to control the device.

I didn't have my SDTrans384, but I've heard a lot of positive feedback. I myself would like to compare my device with SDTrans384. If you are interested, you can take a look here. https://www.dastereo.ru/t/czifrovoj-transport-project-o-dlya-vosproizvedeniya-fajlov-nahodyashhihsya-na-sd-karte-zavershen/99243 This summer, a prototype of my device was visited by several people.

Thanks for your hint, I will definitely check it out tonight.

I can give it to you for testing if you can guarantee that you will return it to me. The price for the new one will be around 1200 euros.

I have already sold 3 copies and can make a few more in a short time.

I am very pleased with the sound and proud of the result.

I tried using USB, SD sounds much better. This was a decisive choice for the type of media.

For example: path /Deep Puple/Made in Japan/CD1 /Deep Puple/Made in Japan/CD2 index 001 /Deep Puple/Made in Japan/CD1 002 /Deep Puple/Made in Japan/CD2 play first track from 002 /Deep Puple/Made in Japan/CD2 press 0021

Forgive me, of course 2 Tb. After the SD is inserted, the device creates an index file on the card. This file is in text format. Each directory is assigned a number from 001 to 999. This number is used to make the selection. The path length limit is 255 characters, and the file name length is also 255. Any number of subdirectories.

The software and device were created from scratch in about 1.5 years. The 2 GB limit is dictated by the file system used. The SD card can store up to 999 albums with 99 tracks each. The style of the device control is as close as possible to the CD transport.

Take a look at my project. I just finished it. Supports wav files 44/16 - 192/24, gapless playback, ID3 tags v.2. IR remote control. SD up to 2 Gb, FAT32 file system. Output - SPDIF, I2S. The highest emphasis was placed on sound quality.
