Ethernet cables

I started something that I really regret now! I changed my Melco ethernet cable (from switch to streamer) to a very expensive Audioquest Vodka and hated the sound! I returned it and got a similarly priced Atlas Mavros cable which I also hated. Both stripped the life out of the music and while they were very smooth and detailed, they never really got off from sounding dull.
Then just for fun (!) i tried a cheap Cat5e cable that i had in the garage and actually preferred that to all of them, including Melco. 
Anyone had any similar experiences?

@mr_gray,  what LPS are you using with your router? It seems like a nice upgrade to your system.

I wonder if it's helping reduce RFI. The coax feed and the router are full of RFI, as is the wall-wart.

@lowrider57 I use an Uptone Audio JS-2 power supply which has dual output. Therefore, the modem and router were upgraded simultaneously with the introduction of the single JS-2 unit. The point is to remove wall warts out of the system. 
That's a very nice LPS. There are no wall-warts in my system. I am using an upgraded Swagman Labs LPS  with excellent results.
My router and computer are across the room and my curiosity is piqued regarding the use of an LPS on the router. As a side note, the router, all cables on this circuit have high RFI levels. I used a RF sniffer and my audio measures zero RFI. 

Have you checked for RF from the coax hookup to your modem/router? 

@lowrider57 What is the Swagman Labs LPS powering?

The RF sniffer seems like the type of gadget that would be found at RadioShack (RIP). I haven't used a RF sniffer but it would be interesting to see it's results after scanning my system. 
The Swagman is powering an iFi reclocker. I use it between my Node2i and Audio Note Dac. 

I've heard the term RF sniffer used, but it's actually a device for detecting hidden cameras and bugs. It works really well, my friend used it and found RFI hotspots. 
I feel lucky that the RF stops at my router and computer and doesn't travel through the ethernet to the system.
