Cal Alpha DAC v.s. Audio Note 1.1

I love my Cal Alpha DAC but I've been having problems getting it repaired. I've been thinking of replacing it with an Audio Note 1.1. Has anyone listened to both dacs?
How would you compare and contrast the two?
Thanks in advance.
You have had problems getting it fixed - really? I have had my CAL Delta back to CAL a couple of times for tune ups and have had no problems whatsoever. Also the Alpha can be upgraded to 24/96 from the factory, so I am a little surprised that CAL is having problems fixing it. I had an Alpha and loved it. - Dan
