With cables and cords, you might want to demo several good offerings from those who have a return policy and hear for yourself what you prefer. I have a BHK/TSDAC/DMP system like yours and there are a lot good, but different, choices. Your system, your ear,
your choice.
Thank you!
I do have JPS Labs cables as well but thinking it would be nice to look at the Audioquest. I had bee looking at their speaker cables for a while and when PSA went that direction it caught my attention. Thought I could not and would not spent the money for their top of the line (I‘d look at something mid-pack or slightly higher, though I’d consider the Diamond HDMI).
If you’re interested in trade ins, give us a call 800PSAUDIO.
Thank you! I will!
The new connections page looks great, with a nice set of recommendations for each product line.

Hi @Paul I take it this AQ tie-up only applies to the US and not the UK
Yes, that is correct. We can’t sell outside the US but, there are tons of AQ dealers and you can certainly view and use our curated picks!

Paul, anyone else… could ANYONE comment on AQ 72v dbs battery pack devices attached to their higher end products?
Anyone have noticed a different? In their line-up, I find this part to be most suspect of exaggeration, AND even if effective, I can’t possibly think it’s similarly effective on ALL cables exactly the same way, as the same device is on Speaker, Power, RCA, XLR, HDMI, USB cables… my engineering brain doesn’t compute how it could work the same across the board.
Thanks

I have these questions as well.
Also what are the expected lifetime of the batteries? Could be an expensive maintenance item over time…
There is no load on the batteries so they last as long as their shelf life.

If there is no load, that implies the question, what is their function? Are they adjacent to the signal path? If so what’s their function? If they were in the path there would be a load upon the battery or the battery would be a drain in the path. If they impart some potential to the shield that would mean there is load as there is no free lunch. I am having some trouble wrapping my brain around the physics
This is what their website says…

Presumably, the voltage applies a charge, ie a potential difference. I suspect this reduces induced noise into the cable.
Thinking about it a bit more, this is just a guess, but if you apply the battery across both ends of the screening, and don’t connect one end to the hdmi connector. This will store energy (current) in the screening as it will be slightly capacitive. Perhaps this stops noise that would have been created by the screening, due to current flow if the screening was connected at both ends
Edit: that can’t be right as the screening would short the battery out. It’s difficult to see where the voltage is applied, but it would have to be somewhere and I’m sure that’s how it works.
Seen this in passive crossovers also - apply a voltage across the capacitors (DC) and it moves the potential away from zero so in theory it will pass AC (the music) in a more linear region in some or other graph of its dielectric material. Details escape me and this answer short as I am laid up and using a tablet only.
Whether it makes an audible difference is another matter ymmv.
Similar principle suppose to magnetic tape bias I suppose you could say.
Hopefully someone on a keyboard with proper electronics theory will respond

I have tried the battery packs on and off and for the life of me can’t hear any difference.

They are said to last years. At least mine still run after 5 year’s time. Still, I don’t think it matters to be honest.

I was just going to ask “is battery swapping just like tube swapping?”…

Likely reason, given your experience & system; there is no audible difference.
