Lumin S-1 Flagship DAC/Server

Lumin S-1 DAC/Server in mint condition. I purchased it new 6 months ago from an authorized dealer. There are no marks, scratches, etc. it is in "as new" condition. It has performed flawlessly and I like the Lumin app very much. I recently purchased a used Lumin U-1 and I'm not using the S-1 anymore.
The sound quality of the DAC in the S-1 is very high end and every bit as good as my $12,000 tube DAC. I'm staying with a tubed DAC as my system is all tubes and that's my preference. Compared to my $12,000 tube DAC, the Lumin has a noticeably lower noise floor, better bass, and more resolution. My girlfriend, who has better hearing than I, prefers the Lumin over my tube DAC. My point is that this is a very high end product and a great value as a server/DAC combination.
I have all the original boxes and cord, and umbilical for the power supply. PayPal adds 3%. Thanks for looking.
