Uptone EtherRegen

I bought one and tried it for 30 days (actually, more like 40).  The results,for me, in my system, were unsatisfactory.  It did seem to offer more detail, but at the expense of warmth, harmonic richness, and musicality.  Alex told me I was only the third person to ask for a refund, so obviously I’m swimming against the tide here.  He was kind enough to return my money, and was a gentleman about it.  YMMV.

Well at least you tried it @doni. But it did ALTER the sound somewhat, no?

Yes, it did alter the sound, just not in a direction I liked.  But again, I was only one in three (at the time) to return it, so I'm definitely in the minority.

If you want dead quiet streaming, go with a fiber network provider. If you have a copper internet provider, you can clean up the signal to your computer/streamer by using the Ethernet-to-fiber converter then the fiber-to-Ethernet converter for much cheaper with the same benefits. 
For me, I don’t have the computer in the audio room and I use the network interface on my dac, so if I didn’t have my 1G fiber network, I would use this Ethernet-to-fiber conversion technique in front of the dac

Sent mine back today as in my system the sound became  forced, bright, more glare, upper mids were too lively.  After 72 hours I had to remove it and I found my ears were at ease again. I know others had great results, but I guess my system does not play well with it. 

Mojo Audio Evo maxed out 
Innuos Zenith 3 with upgrades
Sabon ethernet cables 

Just my experience.
