G'day zerofox
What source/app are you using to bring the tracks to the DAC and then into the Krell?
I hope I can support with this:
Krell suggests using Twonky as the control software for your UPnP/DLNA server. I have a copy of this on one of my back-up music servers but rarely use it because I find its navigation cumbersome. On my primary server I use Illustrate’s Asset (version 4), whose operation I find flawless and wholly reliable. This worked perfectly with the Krell/iPad combination providing swift access to my music library.
