Agear, I would agree with you in that I would like to compare. The Offramp and Dynamo together jumped the performance of my Lampi and digital front end at least 50%.
The DAC is important, very important, but what it is fed is perhaps more important. I will make a bold statement here. I bet my Lampi 4/4 with the Offramp/Dynamo sounds better than a Lampi 5,6 or 7 with no Lampi or Offramp transport.
What I am trying to say is, if you own a Lampi dac and do not use an Offramp or Lampi interface, then you have not really heard that dac! At least you have not heard it's full cababilities. This is based on using the USB input from any computer source...and I mean any computer brand or type.
