Hi all, I'm just waiting for someone to report that you hear different sound with different fiber optic!
But then I lose faith in the Hifi God, and then ...

Love the cartoon! Actually, signal deterioration can occur with Fiber, so I would assume that it also would logically have an effect on the SQ, just as it does with something like the video quality of a 4k transmission. (artifacts, etc.) But I am wondering a bit off topic ....

It's at least 20 years ago when I spent a day at Siemens in Zoetermeer, The Netherlands. The topic of the day was Cat 5 cable and beyond. I can't remember the exact speed but at the time we discussed it was possible to have enough speed in a single fibre optic cable in a laboratory to have about 400.000.000 phone conversations going on at the same time over one cable. At a guess that's probably every phone conversation at any given time on earth.
Putting that into perspective I'm sure it's quite possible to transport the little bit of data that makes up a song in a cable without any problem.
The reason Toslink isn't much good is not because it's fibre optic cable but because it's a really bad version of fibre optic cable. I wouldn't be surprised if fibre optic done properly will be the next high end digital audio interface.

Hello Pim, which I suspect are probably the translators. From Fiber to LAN and back again. What is undisputed, the more media breaks take place, the more errors occur. I'll tell you the quality of the fiber is not to be underestimated. You already get 1 m for 5€ or in the professional area (super polished ends) for 45 €! But is only from large lengths (Km) and large amounts of data authoritative! It remains exciting ...
I like Jay‘s articles (helped by the fact that he also likes one of my favorite foods) but many feel his findings are lacking technical content and not fact based. (see the comments section)
Fortunately that type of bashing is not very common in this community and something that I really appreciate.

Well indeed!
I was very happy with the single SOtM switch, essentially replacing the AQVOX. As I think I reported previously this was an instant improvement.
Then 10 days or so ago the second switch arrived. I connected this to the other SOtM using an ethernet cable. Very happy with the result, basically more of the same.
Once I had received the correct transceivers (long story) I was able to try connecting the two SOtM units via fibre. This also had quite a big effect but one that I didn't really like. Switching back to an ethernet connection between the two units confirmed my impressions. I could hear that the optical connection did some good things (soundstage even deeper, noise floor even lower) but I didn't really enjoy the music. Perhaps the transceivers needed more time to settle? I have no idea.
I then installed a bridge between my router and office switch (which feeds my SOtM), using the same transceivers and some media converters from FS.com (https://www.fs.com/uk/products/35333.html).
Now this was REALLY interesting, it made a massive difference! To the point where my brain is almost struggling to make sense of things. I know it's better - in "hi-fi" terms - but there is some kind of cognitive dissonance going on. I am gradually coming round to the idea that perhaps I just need a bit of time to get used to things. It's like the presentation of music has changed quite a bit and I can't quite work out whether I like it or not. There are some good moments, then moments where I am not so sure.
So over the next few days I will try removing things to understand what is going on and work out which combinations I prefer.
And I have just heard that the Gold M12 is being sent to me tomorrow, so that should arrive next week.
