Well my NT-503 Blutooth and network module stopped working. Dead for some reason. TEAC's customer service at this point is terrible. Zero response from multiple emails to the warranty support contact on their home page last week. I'm not too happy. I tried the hard reset in the manual to no avail. I am curious if anyone else has had issues. [edit: issue with setup - appears ok - but still slow responses from Teac before I figured it out).
