Supra Cat 8 Ethernet cable

I ran my Supra Cat 8 in for a fortnight. No noticeable brightness.

Replacing with TWL Freedom, and will use it to my TV for movies.

I choose Supra Cat8 for its build quality, at 50 bucks per meter, I thought it was a reasonable upgrade. At the time I was using a Node2i with a ARC dac, can’t say for certain if there was definitive improvement over the stock Cat5, at best there was a better sense of clarity? I did recently play with Monoprice Cat8 from Amazon Prime, which is a really well made cable (heavier gauge than Supra). I didn’t detect a difference between the Supra and Monoprice. admittedly, I suck at picking out micro nuances so ymmv.
Nevertheless at $30 for 25ft run it’s a no-brainer for anyone who wants to upgrade or compare against “audiophile” ethernet cables costing hundreds per foot.

I compared a regular Cat 5E ethernet cable, a Blue Jeans Cat 6A, and Certicables Cat 8 cables, all 3 meters.  The Cat 5E was the stock cheap cable provided by the cable company, the BJ 6A cost something like $10 and the C 8 was about $50 on either Amazon or eBay.  I thought there was a slight improvement with each step up in price, mostly what I would call "vividness" or immediacy.  The improvements weren't such that I am seeking out a $500 cable.  I stream Qobuz files through a Roon player onto my network and use a Bricasti M1SE DAC with a network player.  The analog signal is sent to a Benchmark HPA4 headphone amp and I use Kennerton Rognir Planar Magnetic headphones.

I relocated my modem and replaced the Amazon Cat ? cable with Supra Cat 8 with Telegarner ends along with a purchase of a switch .

I never much cared for streaming my music for any serious listening including listening to internet radio, ripped CDs and loaded music files sound quality were far superior to streaming.

AudioSensibility had a sale on this past spring on their Supra Lan cable and internet switch. They Cryo treat their wire and connectors at no extra expensive.

Its incredible to me the transformation of sound from what I had to what I’m listening to now and it’s easy to A-B between the original Lan cable and the new for anyone who denies or insist there would be any difference’s , lol how wrong they are .

The only thing you can do with fancy ethernet cables is cause problems. This is packet based communication...they do not have a tone or a sound.  They might theoretically cause (and thus another cable could solve) grounding issues.
