I wanted to share my experience. I am always interested in the wisdom accrued by others. Curiosity, open mindedness and humility are important attributes in most pursuits including this hobby.
I have an EtherREGEN connecting to the Airlens connected to Directstream Mk2.
I initially replaced the stock PS audio HDMI cable with an Audioquest Firebird HDMI between the Airlens and Mk 2. Significant improvement in sound quality.
I was pleasantly surprised.
Next replaced a 4ft length of Belden Ethernet cable with Wireworld Platinum starlight 8 Ethernet cable between EtherREGEN and the Airlens.
Dramatic improvement!
The quality of digital cables has a significant impact on digital music.
The impact on sound quality surprised me.
I am interested in learning more about digital music reproduction. This stuff fascinates me
