OK. good point. I am using a rather cheap Mapleshade Optical cable
that could be the reason for the 96khz limit
I will try finding a higher grade and/or shorter optical cable.
in the meantime, does anyone here use the Mapleshade and finding 192khz as an option?
I'm not a DAVE user, but it seems to me that 96,00 is usually the best one can get out of optical. Rare that one can get higher.

I think it depends on the vintage of the iMac whether 192kHz optical is supported

More importantly, if you're setting output this way, every time you change your music sample rate, you'd have to change your Mac setting. Otherwise you can play 44kHz music and iMac would upsample to 96kHz and feed that the DAVE instead of letting DAVE's superior upsampling kick in at 44kHz

@paulchiu My question is what files do you have that require these higher settings?

I have 24/192 files from HDTracks. They sound great using USB but I am moving the DAVE farther away from my iMac and servers so needed a really long cord. I had this 16 feet Mapleshade optical cord that was collecting dust, so i tried it.
The DAVE does make higher rate tracks, as high as DSD512 sound really great down to 44.1 using the optical cord. Setting it to 96.0 made the sound even clearer so I wonder if 192 would be better still.

I tried many of those contraptions to the point of exhaustion since I bought the DAVE in early 2016. Where my other DACs worked fine with a simple USB cord, the Chord DACs like Hugo and DAVE did sound better with a few of these devices. Still, the differences are minor and the added stuff just getting out of hand.

I ordered a 4M all silver USB cable from Konstantin from Lavricables, will see how it sounds with the DAVE shortly


You could try one of those USB over ethernet contraptions. Though the subject is likely to try your patience and/or wallet.

USB supports 5m cable length:

Hi: I used normal Toslink connectors (CD player to Hugo) and not the mini one as per your link so depends what you need. This is what I ordered: http://www.sysconcept.ca/product_info.php?products_id=364

This is the name:

1 x 1300-strands 24/192, Toslink Prem. Optical Cable 0.05 to 15m
- Connector Color: Silver
- Length: 3m

They also have all other kind of connectors which will take time to find what you want...

Edit: To be honest looking at your link (the picture) it seems that it is the same product as per my link. I am not sure what connectors there are in your link, but my link has the normal Toslink connectors (not the Mini that DAPs often have) so depends what you need.

I would recommend Sysconcept optical cables from Canada which are great value and do 24/192 with the Hugo... 3 m cable i am using so should work with Dave as well. I am based in UK and got the cable quite quickly.

But isn't the Sysconcept plastic and not glass fibers? There seems to be some controversies with regard glass fibers and their superior transmisssion versus plastic. Does anyone have a definitive answer about utilizing glass or plastic fibers and durability for portable use like with the HUGO2?

The Sysconcept optical cables are very well built. They can have bends of 90° (which you can't do with glass) and still transmit 24/192kHz music. They use many micro strands of high quality and polished lenses that don't interfere with the transmition and practically eliminate modal dispersion. I've used one for the Mojo for the past year and a half and I used it with the Hugo2 on tour. No issues whatsoever.

Absolutely no worries with the Sysconcept cable IMO.

Excellent. What length would I need to go from HUGO2 to source strapped to the HUGO??

Does anyone here have the DAVE stand with the shiny nickel chrome legs?
What do you use to remove the haze besides the tiny cloth included?

Thanks!
