Inter Connects - What I know and don't know

@69zoso69 - - that Ludic Power cable is very affordable considering the materials crafttsmanship and design. It should be a very good performer

The Zavfino cables should also perform very well, since I am yet to hear any negatice comments about them.

In my own quest for great cables, one thing that I became very aware of is allowing sufficient break-in time. Ive had cables that took over 400 hours to sound their very best.

But generally...

1. cables can sound very good immediately
2. after about 20 hours they can start to sound as little rough around the edges - not as smooth
3. 60 hours and up, they start to shine again
4. 100 hours and they are almost at their peak
5. 150-300 hours you may start to really notice the appearance micro details in the venue acoustics - i.e. the very small echoes and reverberations of the concert hall

My own break-in method is to run my streamer 24/7 for about a week and then return to normal listening for a month or two.

You should be hearing some very nice improvements with the cables you have selected

@ghdprentice - glad you enjoyed the post  - and I definitely agree with your statement...

There are lots of variables… which is why different companies have pursued many different approaches. 

Cables can get very complicated - if you let it🙂

@atmasphere  thanks for the followup and link. I read it and understand it in and of itself.

T+A previously stated that pin 1 is connected to the enclosure (chassis) and not signal ground so this would suggest that they do match the "recommended practice" in Figure 1b of the article you linked. i.e. "equipment using 3-pin, XLR-type connectors must tie pin 1 to the chassis (usually called chassis ground) -- not the audio signal ground as is most common."

So far so good. Now, that's where the article you linked stops.

T+A then said "The analog signal circuitry of the DAC200 is referenced to the analog signal ground" and that this matches figure 3 in AES48 Draft. In this figure 3, the pin 2 and pin 3 (signal circuits) are tied to the REF = "Signal Reference" which I assume is what they meant when they said "signal ground".

This is where I am having a disconnect - isn't this the same thing as when you state that pin 2 and pin 3 need to reference each other and not 'ground'?? I assume you mean chassis ground, not the REF = Signal Reference in the AES diagram.

I don't believe the DAC uses an output transformer ('The generation of the balanced audio signal is already done in digital domain - not in analog domain.') so isn't it possible that the differential circuit could legitimately push out twice voltage for balanced vs SE and still remain AES48 compliant?

Thanks for your patience and understanding, I am learning a lot.

@nquery I don't see any figures in the document at the link which have the signal pins tied to 'REF'. If they were tied in such a fashion, I imagine they would be shorted. Perhaps you can list the page number on which the figure is found?

@atmasphere See figure 3 on page 7 of AES48 Draft. Maybe I was being presumptuous by assuming that the signals pins == "signal circuitry" in the diagram. The REF label is next to the black lines coming down from "signal circuitry".
