"Audiophile Grade" Ethernet Switches - The new generation
Here is my EtherREGEN review after burn-in and extended listening:

Current Setup
   
A simple UPnP setup using a MinimServer to get music from a NAS and serving to a pair of Devialet Phantom Gold (on DOS1).  Running convolution room correction on MinimServer. Using wired connections with standard Cat6 Ethernet cables to a Netgear Orbi switch, except for a Supra Cat8 cable to the Dialog (connected via PLC to Golds).

EtherREGEN Setup
   
Added EtherREGEN to setup with an additional standard Cat6 cable on “A side” and connected the Supra Cat8 cable to “B side”.

Listening Impressions

“WOW!” Was expecting some improvement but not such a big jump. Often, a new component may introduce subtle changes which require careful listening and many comparisons to identify any improvement.  For the EtherREGEN, the changes were obvious in the first few minutes of listening.  The background was darker which allowed more detail to come through.  All smearing was removed with a clarity that was unsurpassed.  Diana Krall’s “My love Is” starts with finger snapping. I have never heard how precise that snap was until now! Similarly, an old favourite, Salvatore Accardo’s rendition of the 1st movement of Pagnini’s Violin Concerto No. 4, sounded wonderful. It is the closest violin rendition to my benchmark, a live concert at a dedicated concert hall.

Have spent a lot of time doing convolution room correction to correct both impulse and phase. Managed to remove a significant amount of smearing and improved the sound stage.  The EtherREGEN essentially “completed the room correction” (not sure how else to describe it?) by removing all the smearing.

An A/B testing was not necessary, but I did it anyway.  There was a stark difference between the current setup and the EtherREGEN setup with the darker background and no smearing the obvious differences.

I could not stop listening the first evening and am still amazed at what the EtherREGEN could do. I bought the unit to evaluate (has a 30 day money back guarantee). It is NOT leaving my setup! 

p/s a linear power supply does improve things, more later...
