As you may know Alvin ships his DACs with 100 hours of burn in. This is a very cool thing. Not many makers do that. Now when orders back up could the 100 hours turn out to be 5 hours?
I bought the same DAC in December. I was traveling for the holidays
so I loaned to a buddy to get some hours on it.
The instructions advise against turning it completely off.
Rather use the standby mode.
It it does not sound better than the the bluesound something is very
wrong. Contact CS at Denafrips and let them review setup with you.
If it is defective there is a warranty. Use it.
