Peter,

Not sure why, but I got it to work.

My set up was uR=>audio quest dragonfly=>nordost usb=>isoregen=>auralic DAC. I simply hot swapped in the Lush^2 while leaving the dragonfly in the uR and the isoregen in the DAC. I got an immediate connection that continues to work.

Thanks again. Cheers.

I have only used the configuration as shipped. I will try connecting everything.

I have tried every possible power up/down permutation.

I have not changed the Isoregen switch but will give it a shot.

Thanks for the suggestions. By the way, the Lush^2 is much more enjoyable than the significantly more expensive Nordost cable.

Yes, the system works with other USB cables. I'm currently using a Nordost with and without the Isoregen.

I purchased a Lush^2 last year. I originally had a lot of trouble getting it to work in my system, connecting an utraRendu to an IsoRegen/Auralic Vega DAC. Alex from Uptone suggested that I change the order to uR/IsoRegen=>Lush^2=>Auralic. It worked immediately and I had many months of listening pleasure.

A few weeks ago I had to disconnect everything to re-position some components. I have not been able to get it working again. The uR simply doesn't "see" the DAC. I've tried everything I can think of such as powering down/ up components, different place of the cable, etc. Nothing works. Does anyone have any ideas? TIA.
