I think you have got to the core issue here. When I spoke of galvanic

gound planes do not become part of the signal), but I used the wrong
terminology. Thank you for explaining it properly!
OK - I

OK - I can see all of that. These AC leakage currents come from where?
eddy currents induced in the casework? across the x-former secondary?
My guess is that they could come from a wide variety of places that we

that over many years I have consistently found that balanced connections
sound cleaner than unbalanced, even using short cables.

Basically a TRUE balanced connection is:

HDMI audio is digital (just like HDMI video), so the whole

interested.
Long runs of unbalanced cable are susceptible to interference, such as
picking up a hum from adjacent AC wires.

You will get varying answers to this. IMO, no, it doesn't matter for 3ft
connections at line level, such as between SB and pre-amp/amp. Balanced
is really important for very low level signals such as microphones.
I'm one of the people who disagrees with Phil on this.

The most obvious benefit of balanced is the relative immunity to

that some capable speaker designers add special caps in the right

break the voicing that was done by the developer completely.
I build speakers since ~25 years and you may wonder what cheap parts are
even in high priced Infinitys back in the 90s. Many electrolytics cause
their 18dB filter design back then would have been way to expensive.
Foil caps were very expensive back then! Most likely you can exchange

Thanks Phil. Does this matter with the short runs between components

I think that the consensus is that very high quality (and expensive)
