Cant advise just yet on which DAC to purchase.. However, i pulled the trigger yesterday and i am now awaiting the arrival of a Callia... After researching countless reviews and looking at DAC after DAC at this price point and other factors weighed i felt very comfortable with my decision on the Callia.. Plus it was on sale ( yesterday was the last day) which made it that much easier to decide. Frank and Janice were prompt in their response and i have to agree with the person who was at the beginning of this thread, dont see him now. Anyway, they both were courteous and very professional and the warranty was recently extended to 3 yrs., A no brainer in my book.. PS, i recently read a thread where a buyer had extremely poor service with Mytek and had not recieved his unit after several months. I ruled them out immediately afterwards. The only ambivilence was the Chord Hugo 2 at $1,800. That being said i got the Callia under that😏 so no worries here... plus, i already have the mojo...
