I decided to stick with the Offramp and just purchased the Dynamo power supply for the Offramp. Perhaps someday I can compare both the Lampi converter and the Offramp. Like to hear both in my system.I can't comment on the sound but the Lamp transport is a much much simpler setup. All you need is a digital cable between transport and DAC and run Logitech Media Server on ANY computer with horse power. No special drivers, power supplies ...
Now if the Lamp transport buffers data before play, using wireless and generic cables will yield the same performance as wired and audiophile grade cables.
I run a similar setup and prefer Logitech Media Server over eLyrics and JRiver Media Servers.
For home music servers, I would run something similar to Bryston BDP-2 or ethernet.
