I have now confirmed that using a DAP Questyle QPR1 as a digital source that neither KabelDirekt nor Sysconcepts plastic fiber cable works with DAVE for 192/24 but both cables work perfectly with HUGO2. So my conclusion is that the Toslink receptical on the DAVE is either less sensitive than on th HUGO2 or there is simply a mechanical issue getting the transmitted light deeper into DAVE’s receptacle. Has anyone been able to modify the Toslink cable insertion plug to seat deeper into the DAVE with success?
I don't know if you can see on the attached photo but on the left connector I unscrewed the cap a bit, maybe 5mm, and then cut off the exposed threaded plastic which means the actual optical connector can be pushed home into the Dave socket until it clicks in place. The connector on the right is unaltered.
Did that mod fix the issue permanently?
What cable is it? Glass or plastic fiber?
My issue was just not being able to get the plug fully into the Dave socket and so no connection was possible. The modified 2m length cable works perfectly with the Dave. It is just a cheap one and I do not know the construction. This is it . . . .
I've had no issues with 192 KHz sample rate content using this very inexpensive cable from KabelDirekt from my motherboard optical output to either my Chord Mojo or Chord DAVE (I bought the 12.5 meter version):
The original Toslink cables supplied with the DAVE are readily available in different lengths from Farnell or Newark.
I agree with Rob Watts that sometimes audiophile cables induce more RF noise and some are poorly constructed since they are assembled by hobbyists and small companies that don’t have the resources/access to more advanced construction methods.
And of the 110 items listed at Farnells, which is the one Chord supplies with the Dave?
I wondered if anyone else had noticed that.
The cables are from Pro-Signal and you can select any length you need. Chord includes the PSG00881 with the DAVE. I suspect Chord sources their cables from Farnell because the exact DAVE, Hugo, Hugo2, Hugo TT, Hugo TT2, and Mojo cables are all available in bulk there.
Just to be clear, do you mean this one, with 2.2mm OD (presumably outer diameter) rather than 4mm?
The PSG00881 that I linked to in my previous post is the one supplied with most DAVE units. However, it’s possible that over the years they shipped DAVEs with slightly different cables.
Okay thanks. That cable has a 4mm outside diameter, which I think might be the one used by most Toslink cables. There is however, a 2.2mm diameter termination, which might be the input fitting used on the Dave, but not other Chord DACs. That would explain why 4mm terminations do not fit snugly into the Dave, and need to be trimmed back in order to do so.
Very kindly, Chord are sending me a further Toslink cable for the Dave for my second optical connection, so I’ll do a quick compare when it arrives, and report back.
Do you have links to all the other cables supplied with the DAVE?
Hi @Jozurr, I will have to look up all the listings again and cross reference them with the cables that shipped with my DAVE. I ended up buying another brand new DAVE so its easy enough to do since its probably the newest DAVE Blue Bird Shipped to date and everything is still in the box. I'll send it to you via Private Message.
