foam tips are more comfortable when measuring, indeed. but they tame 8kHz and 10kHz (and maybe others) resonances a few dB.
after trying some methods to keep silicone tips into the coupler (press with rubber end, clips..), found you get the best results by using a good amount of bluetac around the shell and the coupler to keep them together; no distortion added
The difference is negligible and for the most part imperceptible (obviously, I've compared both). If you're speaking of resonances one could argue that "a good amount of bluetac" on the coupler would affect the resonance a lot more. Either way, I find all these discussions about 'the right way to measure' and 'the relevance of measurements' and 'different hardware invalidate data' etc banal and about as pointless as debating burn-in. I know there are many people who like to see the graphs which is why I add them to most of my reviews. Otherwise, I would save myself the time and effort by not doing them at all.

I can say without a doubt the main thing you need to get perfect with a coupler is the distance between the end of the bore tip and the microphone diaphragm. If this changes, you will have skewed measurement. I really think people ignore this entirely.

well, just check the different response of foams (red line) and stock silicone tips (black line) with kz zs6:

it's near -5dB at 8kHz-10kHz.

the bluetac is located around the shell and coupler, and can demonstrate that it doesn't alter FR nor distortion.

sorry, i was only trying to help, because had same problem. didn't pretend to discuss anything

Been listening with my DM6 for about 6 hours and in that time I have heard a rather loud pop coming from the right side twice. Any idea what it could be? Never experienced anything like it from any other IEM ever. Very strange.

Hi guys, I just got the BGVP DM6 and its an amazing piece.

However its really sensitive, and when used in conjunction with some audio cable extenders, I notice an intermittent high-pitched soft whine every couple of minutes. There's no issue when using the cable extender with other high-end headphones/earphones. Is there a way to fix this without changing the cable extender?

Add IFI EarBuddy or 20 OHM impedance adapter to remove noise ?

That pop is your DM6 virginity, don't worry welcome to the club.

Sounds like a pretty good description of the difference between an 'Audiophile' and a 'Music Lover' (generally speaking)
I produce music, have a small studio, etc. That is probably why.

Ah cool, Me too although I would like say I have a medium sized studio. Although its not mine, Im the only one that uses it! - There are some benefits too being a sound engineer :wink:

I do tend to oscialte between the two - sometimes loving the detail and sometimes loving and appreciating the music.
Knowing too much about audio itself though can sometimes make it more difficult to just relax and enjoy the music. A Blessing and a curse :/

Thanks for the tip! I ended up getting the iFi IEMatch and it cleared the irritating audio whine!

Just a question about this product - there's the "ultra" and "high" setting on the IEMatch, do you know which setting is ideal for the DM6? I am currently running it mostly from a ALC1220 on my desktop motherboard.

HaHaHa. Never thought I’d hear that kind of answer. I normally listen to music on 18-30+ hour sessions. And have for the last 8+ years. Actually considered that two of the BA’s blew.
