Ozzy - Thanks for your share. I have tried several filters Audioquest, Ifi, Pink Faun with little improvement. With Stack’s return policy and your feedback why not try!
I inquired Stack Audio on what would be the recommended way to install the SmoothLan in my set-up which includes optical. Below is Josh’s response. I thought this might be helpful to others.
From customer feedback and our own tests, I would recommend the following:
1. Router
2. Ethernet cable
3. Fiber Media Converter
4. Optical cable
5. FMC
6. Ethernet cable
7. SmoothLAN
8. Music streamer
Placing the SmoothLAN between the last Ethernet cable and the music streamer ensures that any potential noise or interference introduced throughout the entire network path is filtered out just before the signal reaches your Hi-Fi system. This approach maximizes the effectiveness of the SmoothLAN's noise reduction and signal purification capabilities.
Hope that this helped!
