CHORD ELECTRONICS DAVE

[griff500]

This sounds like a bunch of BS to me, to be honest. How the heck do these things reduce EMI without corresponding capacitors to create LPF? Someone enlighten me here.

I thought the effects of ferrites were very well established.

Would you care to share how they are 'improperly constructed'?

Which ferrites did you use and how did you determine that performance was significantly better?

We’ve discussed ferrites many times I‘m sure most members are tired of it and don’t wish to revisit the discussion. I previously posted the information in this thread as did many others. I determined the basic cables were better because they worked while the other cables in question caused severe audio distortion and the display behaved erratically.

I do not recall the discussion and I hadn't heard of anyone else having issues with the display or experiencing 'severe audio distortion'. My experience and that of everyone else I have seen has been positive.

Maybe we are discussing different cables...

I assume you returned your cables for a refund.

It’s like a weak inductor with broader attenuation of MHz level frequencies. I am still puzzled at why you would want to attenuate high frequency components of bunch of square waves. I think over engineered shielding is where you should put your engineering dollar at in a digital cable and not attenuation of high frequency waves. Anyway this whole ferrites on digital cable puzzles me.

You may be puzzled but it does work.

Whatever “work” means I guess. You may just like the objectively worse signal because it made your dac sound a certain way. Did you run the cable through oscilloscope and determine better square wave property by using ferrites?

I'm sure everyone, including Rob Watts, is wrong and we all just prefer the results of a worse signal.

I don't use an oscilloscope - I've only got speakers and headphones.

Chord is recommending ferrites on BNC cables for their dacs? I didn’t know that. I will remember to ask them when I see them at shows.

I honestly don’t know any other dac manufacturer recommending the same thing.

I've used M Scaler almost each day for two years and never had any problems with ferried cables. Neither with DIY, nor with Wave Storm. The only defective cable I've ever come across was one of the two stock cables included with the HMS.

Not what I said, but don’t let that stop you trolling.

Little do you know, the cables have in fact caused damage and at least one DAVE was returned to Chord for repairs. You can contact them directly to verify the situation.

Nobody ever said that ferrites are intended to make "a better square wave". Ferrites were intended to supress interference generated by FPGAs. And Rob told a hundred times in this and other topics how RF interference affects the operation of the DAC.

Surely it’s beholden on you to prove your statements.

I still don’t see the ’many others’ that you said have posted about this.

The only way I know to damage the DAC with a cable is a short circuit. This theoretically can happen due to problems understandable to everyone: poor soldering or crimping, mechanical damage to the cable or connector. It has nothing to do with ferrites.

How can inductance added to a cable by a ferrite damage anything?

He is claiming they are not constructed correctly…
