This was posted as part of my description labeled as my subjective finding relative to the sound of the D2. I did not make that claim out of this context (or at least tried not to). And neither have I meant to say that it is scientific fact that the M8A v3 is bright / lacking in bass. All I claim is that it is clearly audible to me that my M8A v3 is brighter and has less bass than my D2. I'll make another claim, my M8A v3 also sounds brighter and with less bass than my HP Probook laptop audio out sound to me.
To me it seems like my particular M8A v3 is off in frequency response (or something else which gives a perceived deviation from a flat frequency response), but who knows perhaps both my D2 and laptop out are off, not likely to me but could be.
I only wanted to post this as a warning to other forum members that it's quite possible that other M8A v3 out there have the same thing and that possibly the M8A v3 does not measure as well as the M8A v1 did. Absolutely not sure, but my personal experience makes me think it could be the case..
Sorry if I wasn't clear enough about this and indeed didn't want to start a personal debate about but my apologies for continuing it and won't post more on the matter.
And no hard feelings btw, I like questioning subjective audio claims in general, perhaps I took it a bit too personal
Btw, I don't have any ADC here now. Can get one but tomorrow my M8A v3 goes back in the mail as a return. Otherwise I would have tried to measure it all. (well actually, I have a bad "mic in" input on my laptop, perhaps I can give it a quick go if I have time this evening)
Cheers!
