I believe there are a number of defective NT-505 out there concerning not being able to connect to the Network. Mine was fine for a few months then began a develop a sporadic issue of not connecting and final the unit just would not connect no matter what dance I performed. It was sent to the US authorized repair facility and came back and connected. I have not had a connection issue since, however now I am having issues with ROON not recognizes the unit as ROON certified. Prior to sending it for repair it was being recognized by ROON but after the original firmware update that included ROON certification. I believe ROON is not recognizing the TEAC due to a ROON update. I tried using the TEAC program but this would not work so I am hoping if I can reconnect to my PC and go through all the steps I did originally to set it up and upload the firmware again ROON will recognize the TEAC, but this is a big pain so I haven't done it yet. Using the TEAC with ROON now is only using Apple Air Play, which sounds OK but not as good as ROON's native file transfer program.
When this unit is working properly it sounded extremely refined and interfaced with ROON and Tidal beautifully. I have an Auralec DAC/Streamer and a Bystron DAC and the TEAC rates right up there with them. Each has their own sound signature and I love them all. Unfortunately the TEAC seems to be the most complicated of the bunch to set up and get going initially and there does seem to be some units floating around that have a network connectivity issue that needs the factory or an authorized TEAC repair facility to fix.
Concerning the external clock, form all I spoke to and from reviews I read where these people have had experience with the external clock the opinion is the clock does not make enough of a difference to warrant its expense for a home hi-fi setting and that it is directed more towards a professional environment.
