The original GigaFOILv4-INLINE (here) was basically an optical isolator, similar to the LHY product. The same folks that brought us the GigaFOILv4, DJM Electronics, now offers the fancier looking, Streaming Audio Ethernet EMI Filter (here) that uses “proprietary Digital Signal Processing (DSP) techniques” and costs about 4x as much. Maybe it works better. Does it work better than the Network Acoustics ENO 2 that uses transformers to isolate, or the more expensive MUON PRO? Who knows? Two $30 converters and two $80 LPSs may perform just as well, or not. I have tried multiples of these things in my own system and the only thing I learned for sure is that they just keep costing more. In the end, we all seem to find our own path.
Network Switches
Another digital question from an analogue guy.
I am currently running an Electrocompanient EDM MKII ( Streamer DAC) and a Small Green Computer Sonic transporter. Both run off of a Trendnet ( unmanaged) basic switch.
Would an upgraded switch have any sonic impact?
If so what switches in the 500 dollar range would be recommended?
