He's wrong.
Modern analogue output stages (assuming he's referring to the DAC output stages) are broadly similar to a lot of DACs on he market today, many even still using the ubiquitous NE5532 opamp.
All modern DACs (delta sigma types) sound (and measure) better than the TDAxxxx series of...
I have several old optical cables, well used and abused, and I take no care over storage.
I've never had any issues with any of them.
Contrary to popular belief, optical connections are surprisingly resilient - and I can actually pull the plug out of the socket and just hold it close enough to...
It's highly unlikely to ever encounter cables with a really high impedance, I just added that comment as an aside.
I do however have a really thick (it must be 8mm to 10mm thick) 1m long interconnect that has such high capacitance that it dulls the top end. It's a Chinese made cable that came...
Not that impedance really matters, because with RF connections (and typically digital) the impedance is matched at both ends, where as a typical audio connection can have an output impedance from ~0 ohms to 10k ohms, and an equally variable input impedance depending on the device - this could...
He means that the amplifier driving the sound bar speakers has floating outputs - this means that neither (+) or (-) speaker outputs are connected to ground. So you are probably shorting one side of the amplifier to ground, hence the hiss. The amplifier is probably a class 'D' which typically...

The goal of galvanic isolation is to prevent ground loops, and not quite as your explanation above.
Most good quality CD players from the 1980's had a small transformer on the coaxial output for this very purpose, although as most CD players were double insulated (and as such had no ground...
If you expect Sony to cover any warranty on imported units you might be in for a surprise, as they probably won't honour any guarantee.
These will be regarded as 'grey' imports.
I think you would be better off looking for something from another manufacturer that is available in your country...
So instead of the connection being:
router => switch => streamer
You want to change it to:
router => streamer
To answer your question: "Is the "new" connection better than existing? "
It won't make any difference.
My qualification to answer this question: I have worked with various...
The internal voltage will likely be 15-0-15 (+15v gnd -15v) (this is typical for opamps) but it could be 18 gnd -18 - which means 30v or 36v in total.
This will be derived from an internal step up as @Stephen Bayley has said, and will have ample voltage swing.
