Uptone EtherRegen or Gigafoil v4???

You can use ethernet now with the advent of Network Acoustics ENO ethernet filter and cables. Amazing sound without a bunch of boxes.

I'm an Eno Ag user as well, it replaced an etherRegen. In the end I found the Eno Ag to sound better in my system and since it's a passive device I was able to eliminate an LPS. 

The Gigafoil works much like using two FMCs with a short run of fiber between them. 

I haven’t used the ER, but I can definitely vouch for the Gigafoil in my system. When you can get an audible improvement for $500, I’d say that is a good deal.  Does it “blow me away” or “sound like a totally new system?” Of course not. But it is an audible improvement.  I have generic CAT6 from the wall to the Gigafoil, then generic CAT7 from the Gigafoil to my MSB Discrete DAC.  I am thinking of putting in a ENO Ethernet cable from the Gigafoil to the DAC, but curious as to whether there would really be an audible difference there . . .?

@moto_man,

I suggest installing Supra Cat 8 LAN cables between wall to Gigafoil and then Gigafoil to MSB DAC. You are very likely to hear audible improvements over generic CAT6 due to superior shielding and noise reduction.

Agree with lalitk that Supra is big value for money on Ethernet cable front. I use them all over 

I use a Gigafoil. Not essential but good easy streaming tweak. More of an improvement with my old Naim setup for whatever reason than with my current totaldac setup 
No dropout issues 

Curious about ENO. As noted above, possible to pair with Gigafoil
