Lumin A-1 or Lumin U1

please give us a ring audio doctor in Jersey city NJ we have a lot of experience with digital.

We sell Cary, Mytek, Lumin, Aurender, NAD, T+A, Naim, and many others.

As per the Lumin it is a fantastic product and is very musical.

It sounds like you have a lot of questions. 

I love the Lumin app for iPad which I use with microRendu. Intuitive, reliable, no glitches or freezing. Cheers,
Spencer

My Lumin A1 is one of the very best purchasing decisions I've made in the 30+ years in this hobby. In almost two years it's worked flawlessly, and sounds so damn good that I wouldn't dream of replacing it.....which is why I hope like hell that Lumin gets aboard the MQA train sometime in the future.

...i second what soundqcar stated. I have had my A1 for 3 years and it is also one of the best audio aquisitions  i have made in 30 yrs.The Lumin team is always upgrading the current platform to make the experience better. I have heard the Aurender products and they are good but i like the Lumin better. The app is fabulous.

Thanks for the reviews so far.  Another component has come up...Esoteric N05.  Supposedly very similar to Lumin.  There are so many choices out there right now.
