So you'd rather see actual measured data than read someone's anecdotal report? Welcome to the club.
Wires are from my own experience after using many products out there. This was before I read the OCOS report on cables and did some research. If you are not comfortable with that, there is not much more I can say. I do post my measurement in comparison against a variety of cables I have on hand. Not only that, I clearly state the deficiencies and limitations where I discover as well. I feel this is quite fair an approach for people making a decision. To further my belief that people should listen before they buy, I only distribute through physical stores, and even though they may have there own on line stores, I encourage them to have a pair available to loan to customers to listen in their own system before they decide. Since cables were intended to be more closely integrated with my own designs, we really do not aggressively promote this individually because we know they are not always compatible with other systems, and I feel I myself would not like spending money only to find out it is not compatible with my system.
I spent my own money in the research not to right reports to convince anyone, but to have something that meets my standards.
Everyone in the audio business know that people in different regions have different general preferences for whatever reason. Sorry you do not accept the fact that I have a goal to more appreciation the performance of the performer through improvement of technology as I see fit.
I have not listened to the TVs that reference, but if there is a review that clearly explains the improvements above and beyond current high performance products, I generally will try to find and opportunity to listen to them if I cannot find measured data.
Yes it is the dark side, and possibly a black hole.

Well, if I could listen to them first, that would have been better. Maybe they want to see if people will rave about it in Taiwan some day.
But if I want to base my impression on a report, it makes sense to look at data that relates with my listening experience.
½ of the experts feel the the shield should be connected at both ends.
½ of the experts feel the the shield should be connected at the send end only.
½ of the experts feel the the shield should be connected at the receive end using a hybrid connection (capacitor).
To confuse the math even more. Some pros are using unshielded Cat5 for balanced interconnects.
My thought is to connect the shield at both ends unless there is a good reason to use a hybrid connection.

What might pseudo balanced be?
I read a book years ago, forget the author name, where the author made the case that 'the scientific method' is rather unnatural to humans. We have no innate drive to get to the facts and the truth. We follow authority, religion, tradition to decide what is and what is not true. Or simply accept as truth that which 'feels OK'.
The scientific method requires real effort, and even then, even scientist fall flat on their face often.
This exchange is a nice illustration.
Note to self: dig out that book.

Single ended output to balanced input. Hook negative and shield together at the source, terminate your xlr as normal. Earth currently flow to chassis and diff input still gives good CMRR if you are using an InGenius chip or similar.
Some also call a phono cartridge pseudo balanced as there is no 'centre tap'.
I have to differ on that science has always been common sense to me. There is a need for ritual and mystery but when I picked up a piece of petrified wood while some claimed everything was <6000 yr. old. It made no sense to me even at 6 yr. old.
Some early Japanese car audio IC output are assembled in mirrored pairs, eg.: µPC1181 and µPC1182 are pin morrored (but I bet it's die being the same and only the package bond differs).
For discrete I never seen a power ECB and BCE package mirror... but who needs that
Scott, you are at one extreme end of the bell ;-)
You are lots of things, but not an average guy. Sorry about that.

Check out Sanken's STD03N and STD03P. Mirror image pinout.

Cheers Jan!
I remember seeing that book in a shop quite some time ago.
Bought another for reasons similar to Scott's.
RaneNote # 110 figure 17 shows the shield connected at the XLR end only, but not at the RCA end.
Just for fun this is what it says in my amps manual:
CONNECTIONS
INPUTS
The inputs are made via 2 separate 3 pin XLR connectors wired in parallel. Either socket can be used as the input, the other one can be used to link to other amplifiers (‘daisy chain’) or to the other input for mono signals.
They are electronically balanced and should be connected via a high grade twin core screened cable, as follows :-
PIN1 - Screen (see note) PIN2 - Hot (signal +) PIN3 - Cold (signal -)
The amplifier is designed to operate with fully balanced equipment and ground loops or loss of performance may be experienced if connected to unbalanced sources. If it is unavoidable however, the following wiring should be used. The cable should still be twin core plus screen.
PIN1 - Screen - connected to the chassis of the unbalanced equipment - or left disconnected at the unbalanced end.
PIN2 - Signal Hot
PIN3 - Signal Cold

Well the Shield is also the signal Return, so it has to be connected to the audio circuit common. If it's not also connected to the chassis then it acts as an interference antenna.
