Devialet and USB cables

[Antoine]

Thanks, Antoine, you clarified the issue for me. ?

In your (or anyone's) view, is FW 8.1.2 as good using USB and Regen as using Air Eth? Better, worse?

Thanks!

Hi L, I don't know about AIR/8.1.2 vs. USB since I haven't used AIR for a very long time.

Antoine, how did you connect both the regen and total dac? Mind sharing a photo?

Hi Warpeon, the Regen is connected to my D250 directly using the short and 'solid' USB adapter that comes with the Regen. It is the advised/preferred way to connect the Regen. The TotalDAC D1 USB cable plugs in to the Regen.

The Regen does not fit under the lid of the 250 with the supplied short adapter. Better said, it fits but you can't close the lid. I had mine lying already tilted on the 250 because of the Oyaide IEC power plug which is also too big.

Already shared a picture (with lots of dust ) it's here: http://devialetchat.com/showthread.php?t...3#pid19763 The Totaldac is the little black box hanging from the Regen. The little black box I am holding is the SBooster unit (power filter) that is integrated into the BoTWS linear PSU I use for the moment to power the Regen.

So your assumption is that passive filters like Totaldac or may be Audioquest (obviously presently unknown) perform similar tasks? Also why Devialet needs clean 5V from USB? I tried some experiments with and with out USB power from my macbook to my D250. It needs the power connections to do the " hand shake" to initialize the connection but afterwards one could cut that connection. I do not know which side of that connection really needs that hand shake. I surmise that reclocking could be the major improvement to any computer based audio!

Hi music or sound, yes I think the Totaldac and AQ Jitterbug perform similar tasks and this is confirmed by both manufacturers specifications of the devices. The question of course is do they do it equally well or is one better at it.

I only mentioned the clean 5V feed from the Regen to be complete, as it is one of it's general functions. However you're right that for the Devialet it is not really necessary as it indeed only uses the 5V for handshake purposes but further it is a self powered design. The 5V lead however IS connected to the Devialet so whether the power coming from it is used or not there is an electrical connection which can also be a source of noise so I suppose it's nice if it's as clean as possible.
