That reads like the most important part of the story is missing. Apart from the extended warranty that we and our distributors might give, consumer protection laws all around the world would give one a quick and easy exchange right for a unit that lasts only one day. In such a case the local dealer is the one to talk too.

So what details were not disclosed here?

Ok, so i spoke more with my dealer, and this is the response sent to my dealer from Jeff Petersen of RME USA:

"Either a PSU with overvoltage was connected, or there was a power surge that damaged the DC input regulator. in either case, RME will not cover this with warranty, sorry.

They could try a different power supply... but i do not think that will help"

as i stated, i use a UPS with all my gear and i used the included power supply only and i don't have another to try with the unit.

this is a very disappointing response. I really don't appreciate the fact that Jeff defaults to "it's the customer's fault" without even inspecting the unit. it's kind of a slap in the face. i am an audio professional of more than 2 decades and i know how to take care of my gear properly. i would never put my investment at risk by using an unsupported PSU or not using a UPS.

my dealer tells me that he:

"Can’t exchange until Manufacturer gives us RMA" and that he doesn't have another ADI-2 DAC in stock right now

i don't know what to do. Jeff has dismissed my valid warranty claim out of hand, without so much as seeing the unit. i didn't mistreat the DAC or feed it bad power (it's plugged into the same UPS as my desktop PC, and that is working fine as usual). i don't understand why his response was so dismissive.

Did you ever test another external power supply to make sure it was wasn't just that failing? 9-12V, 2A, pin positive.

I am sure that what Jeff was trying to say is that warranty would not be applicable if damage due to overvoltage were to be determined during repair. Your quote was probably part of an internal communication between Synthax and the retailer that has additional context. Have you tried contacting Synthax directly?

You might have one connected to a Wifi router or similar device that you can borrow for a test. Otherwise, the retailer might be able to provide one before you send everything in. It's well possible that it's the ADI that failed, but a test would help make sure.

As soon as the unit has been examined.

Perhaps because it hasn't been diagnosed yet? What RMA has to do with sending the unit in for examination?

Thanks, I've handed it back over to my dealer and he's gonna keep me in the loop.

I live in Germany and have sent my two ADI-2 PRO FS R BE directly to Audio AG (distributor) to have a known serial defect repaired. Unfortunately, almost 4 weeks have now passed and my two devices are still with RME.

So please be patient. I can understand your disappointment after all the anticipation of your beautiful DAC. But RME is very fair and will certainly find a very good solution. You just have to be a little patient.

Hello, could you please share what is the "known serial defect"? I have owned the ADI-2 Pro FS R BE for ten days. What should I watch out for and is there anything to worry about?
Thanks.
