Sort of a non standard standard ? …

Great post and a perfect answer to my question - thank you!!

How do you know it was a perfect answer?

The difference is on the middle pin diameter.. 50ohm being thicker prox. 1mm vs 0.8mm for 75ohm. My HMS having 75ohm.

The actual difference that affects the characteristic impedance is in the amount of insulation between the conductors as I understand it. There's a picture I can't find where someone showed the signal reflections added to a digital signal by using components with an incorrect impedance. Imagine a square wave with a noticeable, but not huge bump in the top of the wave. Whether it would actually affect an S/PDIF signal in any DAC, or the subsequent analog output, is hard to say.

Anyway, I had a bit of fun with the MScaler: I connected it up to the slightly older AKM-based Schiit Modi 3+. I had a listen to some acoustic music, and, switching between having the MScaler "off" (red), versus at the max the Modi would take (176.2/192 - blue), plucks on the strings of instruments went from having no decay, to having a clear decay. It was very audible. I also had the Modi powered from an iFi iUSB 3.

I only did it out of sheer curiosity to see what would happen -- ie: What happens if you "max out" a Modi, and how much does the audio change.

Ive seen many 'professional' chassis and BNC's with just 'tupperware' plastic as isolation.. thats hardly tuned..

Equipment is simply terminated with a matching resistor at both ends.. at least CCTV stuff is..

If i changed one of those resistors i saw clearly image degradation

He obviously did multiple blind auditions of different answers

Looking at recent stream of posts I can say one thing: I don't understand most of it and I miss the point in those posting completely.

Here is why: I had a pleasure listening to Lumin D2 with Feliks Audio Euforia Anniversary Edition yesterday, later I have been traveling so I used my trusted Mojo 2 with Poly and when I came back home I started listening to my Euforia playlist using Hugo TT2 with M-Scaler. What an awesome day it was, and I really like enjoying TT2 with M-Scaler. The joy of music is the one that really counts in this game IMHO. YMMV.

@alekc Are you posting on a forum to say it's better to listen to music than post stuff on a forum?

I expect the vast majority would agree.

Reminds me of a saying from my old science teacher,
“There’s a time and a place for questions, but in general you learn more with your ears open and your mouth shut than vice versa”,
Music is for listening to but when something is special we can’t help but wanting to talk about it ?

@griff500 A bit like that, yes. What I'm trying to say that I really like and highly value Head-Fi community, you guys have enormous knowledge and experience plus it is a great place for discussion, however I am missing the point in producing pages of posts about audio equipment without actually spending this time to listening and enjoying music. One could argue that you can listen to your cans while typing on the keyboard but for me the best joy comes when I can concentrate on music, not on postings. To summarize: it is valuable and important to post and share your toughs - that is how communities are being build, however for me it is completely pointless to produce ton of pointless posts about particular device while not truly focusing on the music. Just my 2 cents... Over and out - back to listening to:

The other sage bit of advice is that it is often best to keep ones mouth shut and say nothing and let them think you are a fool rather than open your mouth and confirm it.

Confirming light travels faster than sound,
“He looked intelligent until he opened his mouth”

For the poster a while back looking for songs to evaluate the MScaler,
Add Fleetwood Mac’s “Dreams” to the list, at “realistic” rather than “excessive” speaker system volume the opening cymbal hit almost made me spill my coffee …

That is a wonderful cd, one of my all time favourites. Extraordinary playing.

A few years ago @Peter Hyatt posted 'Although not a fan, the Masters version of "Rumors" at TIDAL is worth a Mojo listen: "Dreams" opening sequence. Listen to what Mojo does to the cymbal in the intro. Then, listen to the voice...'

Because of that comment, l compared a few recordings, and did find that one recording had much greater shimmer, than the other recordings, but I couldn't remember if it was that TIDAL version.

Because it directly addressed the topics I was inquiring about. If only everyone could answer questions directly...

No streaming here, all off CD ….
