Hi and thanks for the very valuable advice.
I will keep both, and the SBT for the serious listening.
But i would like to improve the playback from the pc as well
But i think that i am quite close to achieve maybe not the same sound i have with the SBT but decent enough.
The converter is fundamental to isolate the noisy pc and to clock the signal.
Thanks again.
Kind regards,

Is it?
Does every USB to SPDIF converter galvanic isolate the DAC from the PC?
It has to clock (it is SPDIF out). Any clue about the quality of this clocking?

Hi i was mentioning what i understand a good converter should provide:
1) isolation from the pc power (i.e. it must have an independent low noise power supply)
2) a spdif signal with a stable clock.
For point 1) that can also be achieved cheaply with a usb power supply and a suitable cable, like the Teradak U9 i have.
Point 2) is much more tricky.
Only expensive units seem to satisfy point 2).
It is like the old discussion about good and bad transports.
The good ones were rare and expensive, with some cheap exception like some particular dvd players or br players.
I am looking for an exception among converters.
I think also another thing. A very good converter is good independently from the "feed" quality.
Just a decent pc shoud be enough for very good sound.
I do not have the evidence because no one would ever mate a 2-3000 USD converter with a 200 USD pc.
Maybe the opposite ?
Thanks again.

What about the data lines?

2) a spdif signal with a stable clock.
A DAC with a async USB receiver does the clocking. No need to rely on external clocking (SPDIF)

Hi and thanks for the advice
I did not think about data lines actually
You mean that they can carry noise ? that is bad indeed
I wonder what people use as standard solution for this issue
Thanks for the recommendation if the usb optical cable
I see some opinions non 100% positive ... maybe it depends on the actual set-up ?Yes in case of usb dac is done in the dac and this i agree is very good
Mainly i looked at the usb to spdif converter solution with the aim to try some vintage dacs that do not have usb input.
Let's say that a good usb to spdif converter frees the hands.
For instance i have a friend with an old California Audio Labs Alpha tube dac that he is willing to sell me.
I have always appreciated its nice sound when i listened to it.
Thanks again.

I settled on the M2tech Hiface two: cause it's cheap and I'm getting out of the "computer as transport."
The other is the very expensive, - but great Audiophileo II. In my system it absolutely shattered the HiFace, - but needs an USB cable.
And the other is the Wyred4Sound uLink, - that one was in between the two, in my system. YMMV.... etc etc....

Thanks a lot for the recommendation.
I think i will set on the cheap level and use the SBT for more serious listenings.
However where nice the Audiophileo II. Beautiful object indeed.
Thanks again.
