Opposite polarity is not an issue as long as polarity is consistent across all speakers. It would be an unusual case if you were to alternate between mics with opposite polarity during a single calibration session.

Here is a lengthy discussion concerning differences between the two mics. https://www.avnirvana.com/threads/umik-1-vs-umik-2.8397/

I have not revisited this issue since the discussion two years ago. I don't recall ever getting a response from MiniDSP Support, but I could be wrong. Out of curiosity, I ran a few test measurements this morning. I now have three MiniDSP mics, the original UMIK-1 with its CSL custom...

While you may have options to make XM sound better, its quality is nowhere near as good as the high-res streamers like Tidal, Qubuz or Deezer. IMHO, of course.

* Another service you may enjoy trying is Deezer. I have evaluated Tidal and Qobuz as well, and while I found their sound quality on a par with Deezer (which streams exclusively in FLAC), I ended up choosing Deezer because of the interface and ease of navigation. While I agree that volume...

Copy cat! I also have four Hsu ULS-15’s, two in front and two in the rear. Equalization is Dirac Live with DLBC on a Monolith HTP-1.

Sorry, no disrespect meant, but what does this discussion have to do with “Streaming services—can you actually hear a difference?” That was a far more interesting discussion.

This has been an interesting thread. I spent some time this evening trying to see if I can hear differences in the streaming services that I subscribe to. I currently subscribe to Pandora Premium, Deezer HiFi, Apple Music, and Amazon Prime Music. My streamer is a Sonos Port (with the...

I’ll have to familiarize myself with Audacity. Thanks for the suggestion.

What tools or software is there that will allow you to analyze a streaming audio signal and reveal its bit depth and resolution? IOW, if a service says it is delivering lossless FLAC, how can it be verified?

Thanks for your suggestion, but for now I'm just trying to understand the polarity difference. While my equipment and environment have remained relatively stable since the "old post" and today's measurements, there could always be some variables, like slight differences in mic placements, or...

If you had a choice of which mic to use, which would you pick? Or does it really make a difference?

OK, I ran a fresh set of measurements using both the UMIK-1 and UMIK-2 and switched between using the Java Excel driver and the ASIO driver (MDAT attached). All of the UMIK-2 measurements using both drivers are showing negative polarity, while all of the UMIK-1 measurements are showing positive...

No, the ASIO4All driver was used. The 7/5 measurement used the Excel drivers. Do you think the driver selection would make a difference? Did you look at the MDAT file? Something peculiar is going on with the Dirac Off/On measurements.

MiniDSP has responded and they are looking into this issue. I ran a quick analysis to try and identify when the issue first appeared. The analysis results are in the attached file. The issue first started appearing for me in July of this year. I am also attaching a REW MDAT file that...
