These are audio recordings in 24-bit 192 kHz where the RCA line output was connected to Sony PCM-D100 line input (3.5mm jack). The purpose is to compare the relative sound quality when playing CD/SACD with Marantz SA-10 versus HYSOLID and JPLAY FEMTO from the internal SSD of the streamer (Build 02). For details on how this was done, please refer to the previous post. However, the USB Audio cable has been upgraded to Curious Evolved.
I added a track for channels and phase test to help check playback on your laptop/phone.
I will put some explanation here. The first file below is the ripped WAV file from CD. (A) is the output playing physical CD with Marantz SA-10. (H) & (J) are the two players being compared here. Both players read and render the ripped WAV file from CD which is stored inside streamer SSD and send the data to Marantz SA-10 through USB Audio interface. For (A), (H), and (J), the analog RCA output from Marantz SA-10 goes into Sony PCM-D100 which is recorded in 192kHz 24-bit uncompressed PCM as WAV file.
I also tried one SACD, the 9th track of The Absolute Sound 2016 SACD by Amy Duncan – Your Very Soul. I am not putting the original ripped DSD file here since most web browser will not be able to play it.
Can you hear the difference?
Spoiler:
A is playing CD/SACD with Marantz SA-10.
H is playing music files ripped from the same CD/SACD stored in internal SSD of the DIY streamer. Music player is Windows 10-based player, HYSOLID, running as background task with playback control using HYSOLID app on an old Android phone. USB output is through DIY USB filter into SA-10 USB Audio input using Curious Evolved USB cable.
J is playing music files ripped from the same CD/SACD stored in internal SSD of the DIY streamer. Music player is Windows 10-based player, JPLAY FEMTO, running as background task with playback control using Android app, BubbleUPnP, on my Samsung tablet. USB output is through DIY USB filter into SA-10 USB Audio input using Curious Evolved USB cable.
