CHORD ELECTRONICS DAVE

[STR-1]

To be honest I don't know exactly. What I can say is that I connected the cables in the morning, listened a little bit but not very intensive. I heard a bit harshness, but those cables came straight from the box. I went to work and in the evening I started listening. I liked what they did. This was Monday evening. I repeated the session yesterday during the day and I didn't notice any difference in SQ so the cables were probably already in optimum condition on Monday evening.

Thanks. I look forward to hearing good things from this cable.

Well, in the UK at least

Interesting views on AC line and neutral polarity but our power supplies always convert mains AC to DC before slicing and diceing at ultra high frequencies before reconstituting it back in a form the electronics can make use of. So I don't believe anything of concequence can really be occurring.

It is like throw a grilled chicken through a jet engine at full power, so you should not hear any difference or with a highly expensive power cable in my book, but i use both above mentioned things for the looks, and i like to connect my products with the correct polarity nevertheless, but i should sleep very well without the fancy power cable, ( that does nothing) it is our mind and placebo to think it makes a differentiation because it thicker and heavy , our mind pre set itself to listen to the full bodied sound, with darker background with very fine crisp resolution automatically, but the DAVE sounds exactly the same as with a descent shielded "cheapo" cable also.

I have tested this very carefully so i am sorry guys, but you have tricked yourself to think you hear a difference.

So using a overly expensive power cable to feed a switch power supply seems not so clever if you understand the technique and point behind a switching supply.

Placebo it is called...

Then your hearing fluctuating over one day, if you are tiered or hungry for example, you hear differently and you got a more tuff time to focus.

Does the DAVE draw power from Vbus when using usb? Because it's mains powered I assumed it didn't. Just tried inserting a Sbooster Vbus2 Isolator between my mRendu and a Sonore usb hard adapter (also tried with the stock usb cable that came with DAVE), and nothing. Same result when using between my iMac computer and usb cable (feeding both DAVE and Mojo). Should the isolator work with these Chord dacs?

The Mojo runs off battery, but uses the VBUS to detect that there is a USB device connected, and then activates the USB input signal processing circuitry. If you block the VBUS signal, then the Mojo will deactivate the USB input signal processing circuitry, with the result being that you hear no music.
 
I suspect that the same applies to the DAVE, even though it is mains powered - no VBUS signal means deactivated USB input signal processing circuitry, with the result being that you hear no music.

Thanks. It was just a very cheap experiment.

I'm hoping to have my DAVE in time for Christmas (pretty please!!!!) so I haven't done a mains polarity comparison.

Certainly there's decades of anecdotes of a worthwhile difference relating to mains polarity with linear power supplies.

I have used an optimised cable configuration for mains power, when I ran a big Naim system. That had 8 or 9 (can't remember) equal-length IEC power cables running into a single wall plug. That's the most mains madness I've engaged in

But I've never bothered with polarity. I think an FM tuner is the only thing I've owned that gave me the option to even experiment, easily. Everything else would have required tedious re-wiring just to conduct the experiment. No thanks!

Does the DAVE get firmware updates?, like, for example, the PSAudio DS...which has had several...and improved along the way.
Thanks

Questions for Rob Watts:

1) Is it ok to use SHORTING BNC caps on DAVE's unused ports? I read that shorting caps can potentially cause damage on some preamps.
2) If OK to use, would there be any potential sonic benefit with the shorting caps?

Thank you and I will take the answer off the air

If you mean caps to provide RFI shielding, then i think the question has been asked a few times, but this possibly also includes the TT thread as well, and I think Rob said no need, but they are cheap if people want to add them. i have just searched, but cannot find the posts, but you may be luckier than me.

Thanks Miketlse.

I use the NON-shorting caps on the unused RCA ports of my amps and preamps, mainly to keep the dust out, as I don't really hear any sonic improvement.

Some people swear by SHORTING caps; however, I have never used SHORTING caps before and just want to make sure that I don't damage my DAVE using them.

best to get the definitive answer from RW.
