Audioquest Diamond

QQ and possibly silly……

On the Audioquest diamond ethernet cable what does the power pack do?

If I click the button a green light comes on then goes off when I depress.


DIELECTRIC-BIAS SYSTEM (DBS, US Pat #s 7,126,055 & 7,872,195 B1): All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, a big problem for very time-sensitive multi-octave audio. AudioQuest’s DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check.

The button once pushed if no light battery has gone, otherwise it’s fine and just leave alone.

Thanks Dunc, appreciate the detailed reply.

I have to say after running it for 2 weeks I’m underwhelmed, switching back to the melco cable and I prefer the sound……

Will run one more test to be sure but wanted to make sure I wasn’t doing anything silly……


My dealer did not recommend……i stayed with AQ Vodka. I struggle with cables, so now settled i have no desire to change.


Yes, on reflection it was a can of worms I should not have opened!

I used the diamond between NDS and Phoenix Net with the power pack end going into the Phoenix Net but just didn’t sound right….

I thought it would be a walk in the park……i tried so many brands and came to my maybe false conclusion……i was doing fine room tuning. So stuck with one that i liked.

Well if you want to get rid let me know

The AQ Diamond ethernet has a very clean, balanced and extended sound, but quite refined overall and not edgy and “show off” like the Vodka.
May be give it a bit of time (if within return window)? Initially I found it a bit dull, but then realised it’s just quite perfectly clean:)

For me it’s the best vs 7 different I have tried. Full, organic, smooth and involving. So right and free flowing.
I tried the Meicord, Catsnake, Vodka, Blue Jeans, Audioquest Forrest and a no name cat 5.

Are you sure it’s not a fake Chinese one? Came inside the original Audioquest box?

Why fake Chinese? Why not fake French?

Because Chinese are the kings for copying some well known components. I have seen some fake Audioquest, siltech, or Kharma made in China. They cost little and some make great margins on them, selling them as original ones. It’s a well known thing.


As ever i guess its buyer beware…the retail price in the U.K from a dealer is £849 for 0.75 m.

It is a know fact with audioquest diamond cables.
They will inspect it for free, but if they find its a fake they will destroy it, and you get nothing.
Did you get a box with it as that’s the normal way to start to detect if its a real one or not
Did you buy it cheap off ebay advertising as 1m ?

You can even find some fake “Naim” amplifiers.

Is this for an ethernet cable or a new kidney?


It doesn’t actually qualify as an ethernet cable as it doesn’t meet the specification. :pleading_face:


i totally agree with that (having switch from Vodka to Diamonds some years ago).

i have one between the box and the switch and one between switch and 555. The last one is the most important

I still get a chuckle when I read their product specs.

Who cares :wink:,.it’s what it possibly delivers in soundquality that’s important.
Just listen and draw conclusions from it.
