I often think about firmware updates, but never get around to it. Kinda figure, right or wrong, since the equipment is hooked up to the Ethernet that it would update itself. A couple of times when I checked the status of my McIntosh gear it said it was up to date. Not sure if that is right or wrong but works for me.
To the point, I always get great customer service when I call Mac. Each person on the other end of the phone has a unique personality, but they all get the job done. Sometimes stoically but hey, we all have our moods, right. Never been not directed in the right direction. Ron Cornelius was awesome. He kept threatening to retire. I never email. Always call so the Q&A on both sides is efficient.
Mcintosh customer support
Requested Firmware update from Mcintosh for my ageing but still good sounding D150 Dac Mcintosh customer support virtually refused to supply Firmware v 1.02 with me . their answer was,,
( Unfortunately, company policy prohibits me from sending out firmware updates. We used to distribute them openly but they ended up on forums and were installed into incorrect units causing a massive influx in service repairs. At that point the company instituted the policy to no longer distribute them.)
it is so sad that Audio Giant like McIntosh do not care about their customers.
