I have a friend who produces their own designs DAC's and Phonostages.
Recently the latest DAC this person produced, which was designed to present with a perception that there was a underlying Rich Tone, was used in a comparison with a Denafrips Venus II (not with latest FW Updates) and it was quite evident the DAC produced by a friend had shown the Denafrips a 'Clean set of Heels'.
The Venus owner was looking to replace the model following this experience. Vert recently the Venus owner has made it known the model has now had all Firm Ware Updates and the device has lifted to a much improved presentation and a much improved experience.
The friend who builds DAC's is at the Munich Show over the Weekend and has an intention to become familiar with lesser known DAC's that are being demonstrated. Maybe some models demonstrated will be readily available in the US, and not so in the UK.
If the OP is interested in receiving a list of DAC's that made a good impression, I am happy to request info to pass on, I suspect my friend will Photo document a lot of the equipment, this should help with identifying systems in use, which may also be made known.
