Digital isolation between Ethernet hub and streamer

I have a longish run of ethernet cable (50ft) to my DAC/streamer from my router, so I thought I’d see what the ifi lan ipurifier pro could do for me. If anything. First though, I connected it between my 8K tv and router that sits right next to it, to see if there would be any visible benefit. Re-watching the final season of Dexter I had just watched, there was a nuanced difference in color naturalization and better edge definitions but not huge, just nice. The sound difference was more noticeable. Dialogue that was fine before was more detailed and things like actors breaths that had been inaudible before were delineated. Music had more punch and delineation too. Then I moved the ifi lan ipurifier pro to my main rig right before my Bricasti M1 DAC/streamer. I switched back and forth on Natalie Merchant’s song Carnival, with and without the ifi lan ipurifier pro. With it, the conga drums have much more noticeable timbre than without, instrumentals are better separated and the whole presentation is just slightly better. I’ll take that level of improvement all day for under $300! Also, I missed the the ifi lan ipurifier pro on my tv, so I bought a second one. These tests were with the really cheesy power supply the ifi lan ipurifier pro comes with. I have since ordered their high end power supplies. I’ll let you know if I hear any difference with them after I test them out. I really don’t get the naysayers who have not tried a piece of technology in their system but feel qualified to weigh in negatively. The ifi lan ipurifier pro makes a clearly positive difference that both I and my non-audiophile wife can see and hear in our systems. Each system is different, and your experience may be different than mine, but basing opinion on first hand experience is key.

So, I tried the different power supplies offered by iFi for their lan ipurifier pro. Surprisingly, I liked the 9V battery-sized wall wart one that came with the device the best. All of the other ones were detrimental to the sound even after breaking in for a few weeks. Really surprised that this is the case because I’ve heard great improvements with better power supplies in all manner of digital applications. Don’t know why this is the case in this instance but it is. I really like the ifi lan ipurifier pro though. One thing I did notice made a significant difference though was the last run of ethernet from the ifi lan ipurifier pro to the streamer, or TV. The differences between the half dozen ethernet cables I borrowed from The Cable Company were quite noticeable. I ended up liking the Cardas Clear the best and the CardasClear high-speed USB was even better. No idea why different properly designed and manufactured ethernet cables should sound different, but they did in my systems. Satisfaction in getting better sound and video, but frustration in finding more things that should not matter apparently do.
