Uptone EtherRegen or Gigafoil v4???


I've read a great deal about both the EtherRegen and the Gigafoil v4.  Has anyone tried both of these units to compare?  
I've gone to a total streaming system now, and I'm wondering how it can get better than what I currently have.  What does something like these units do to enhance the sound?  Is it worth the $650 for either of these units?

Also consider the Network Acoustics ENO Ethernet Filters.  They seem to be the recent "darlings".
I am a ENO user....biggest advantage with ENO is passive filtration of incoming noise on Ethernet. Read up on ENO here before invest in any other solution,

I’ve had the EtherRegen, Gigafoil and ENO in my system. In the end I kept the Gigafoil and ENO. I have the ENO right before my streamer. I don’t think the Gigafoil is better than the EtherRegen but the ER gave me dropout issues and required rebooting frequently. -Alex
