Here are the modifications to the music streamer that improve the sound quality:
* Updated the power supply. Instead of the tiny digital 5V DC adapter, I switched to an analog power supply. This upgrade helps reduce digital noise and improves the overall performance.
* Updated the analog output. I used better operation amplifiers (Analog Device)
* Updated REL and MIT capacitors in the power and signal path circuits.
* The music server has a treasure trove of over 400 CDs that have been transformed into high-quality WAVE files. These CDs come from some of the biggest names in the music industry, like Wilson Audio, Stereophile, Chesky, and DGG.....
