Tone in a review is irrelevant; only logic is. That’s what I take @djones51 to be saying. And what @amir_asr to be saying in his review.
I was very interested in the EtherRegen because of what Hans B. and others had to say, but the ASR logic is pretty compelling. Here’s one bit of it:
"Perhaps the biggest issue with claims of audio improvement is that your DAC is so far removed from Ethernet that little you can do upstream can impact it. Ethernet has a clock but that is used for communication on the wire. Once a packet (chunk) of data arrives, it is put in memory in the operating system. At that point, it no longer has any timing information much less a clock. It is the responsibility of the application to associate timing with it. And such software notion either works, or doesn’t. If it doesn’t your music will stop or drop out. None of that timing has any relationship whatsoever with the clock that the DAC eventually uses to play data sent to it. It is the audio application together with the DAC (and or Operating System) which determine timing."
If I’m understanding the issue, based upon how the tcp/ip data transmission works, timing is irrelevant; in other words, the receiving device buffers the data until it is certain it has been received correctly.
Consider this explanation for TCP:
"TCP provides applications with a reliable, in-order stream abstraction.
The network doesn’t.
So TCP has to do various things to ensure that it delivers payload in order.
That includes acknowlegements, retransmissions, and reordering.
Now, most networks do try to keep things in order, but TCP can’t assume that.
For example, even if the network does not reorder, if there are two possible paths, one shorter than the other, and for some reason we have been using the long one… if the route changes to the short one, briefly we can have packets in flight on both, and they’ll arrive out of order. This is normal, it happens occasionally, and TCP has to deal with it."

Those who get angry or say "you have to listen to hear it" are welcome to their impressions. They are sure they hear something. But just as the mind begins to hallucinate in an anechoic chamber, the mind also listen for certain effects in order to match its own predilections. Nothing satisfies like satisfaction, right?
