I finally decided to join because of BGGAR's DM6 review on youtube. Actually I found that first and decided to buy a pair when he kept dropping hints that they matched or exceeded the Sony Ex1000's in some cases. I also come from the basshead tree of audio.
I ordered mine in early Nov last year and got them like the 1st week of December, but then didn't open them till Xmas. Anyhow. I wanted to give my review since I've read a lot of stuff and maybe someone will get some good information out of this.
First off my DAP source which I picked because of sound quality is the LG G7 Thinq. I think basically all the modern dual sabre dac based LGs are pretty similar in output. They are highly regarded in most circles although surely not as high quality as you can possibly get. Still, it's powerful, flat response neutral sounding and flexible since it runs android and can push low and high impedance cans.

My audio program of choice is PowerAMP which I have been using for years. I use it in HD 192/24 mode with the high quality decoder and Direct Volume Control (this makes a MASSIVE difference). Sometimes I mess with EQ but it sounds super nice without any with most of my IEMs.. and especially the DM6.
Observations about the DM6. I am not a cable believer. Having said that, this IEM exhibits some special kind of sensitivity, such that I can bump the headphone plug over my jeans and hear static in the drivers. That's.. something else. I decided to try a 80ohm headphone adapter plug to see how that responds and it actually smoothed the DM6 out in a very nice way. Refined it in my estimation. Sub bass rolls off a bit and so does high treble, mids jump forward. I wasn't really expecting the sound signature to change so drastically actually. Whatever, I prefer it straight into my DAP in low impedance mode with no adapter (surprise). I have tried high impedance mode and mids and high treble get 'hot' and I don't like it much. I have to keep the volume way too low and it's easy to overpower the DM6 in this mode. I think this is possibly why some people think the DM6 is sibilant and hot in the treble.
While im on this subject, I've rolled a bunch of tips and I swear, when I use wide bore rubber/silicone standard type tips the treble region gets really hot and I hear and odd 'splashy' effect. I'm thinking the wide bore actually makes a small resonant chamber and maybe it's just my ears but it makes the treble too busy and messy. To be honest I've not heard this effect with IEMs before. Maybe its my ears though. I find foam tips sound perfect with any IEM, create a perfect seal and don't create a treble resonant chamber.
Bass - 9.5 out of 10, With my setup, direct volume control, bumping bass in Poweramp, WOW. Scratches my basshead itch easily. I can get picky about this but overall, i never think to myself, man if only I had more bass. nope, these knock it out of the park. Super fast, accurate textured bass. I've heard better.. maybe barely. These sounds like a good dynamic driver.
Mids - 10 of 10. Pretty much this IEM is neutral as heck. Give it a track with forward vocals, you get that. Female and male vocals both sound 'correct' and lush to my ear.
Treble - 10 of 10. These ride that special line between an ultra detailed IEM and something fatiguing to listen to. Maybe you can find something with better high end but I've not heard it. I have read a lot of people that say the treble is too hot. It is not and I really don't think there is a problem with manufacturing. I think this is probably due to DAPs with mismatched impedance and maybe tips. I can easily slap on some wide bore silicon tips, run my DAP in high impedance mode with the 80 ohm adapter and OUCH. Sizzling treble in a lot of tracks.
Soundstage 9 of 10. For an in ear, these are damn good. I've heard some Sonys with unusually large sound stage but they don't have the resolution of these. I find myself enjoying the 3d quality of the output a lot. It's addictive.
Instrument separation - 10 of 10. I record and mix live guitars and other instruments and the DM6 can be used for mixdown and even live monitoring. This is a complete winner in my book. I can clearly hear each part of mixes, amazingly so. Love it.
On the subject of mixing, I have 4 sets of studio monitor speakers, along with a high end flat response monitor subwoofer. I use these speakers as my 'reference' for IEMs general sound signature.
Value - 12 of 10. I think you can pay a LOT more for an IEM and not get as much as the DM6.
Cables - I don't like thick cables though since I spend long hours working out with my IEMs. Whatever, you can replace em. Maybe they change sound quality, maybe not. I feel like tips, audio decoder, and other things matter more.
Fit - The tips bore size is large for my ear canals. Larger than any of my other IEMs. It's pretty easy to get a bad fit on one ear a lot of times. I wish the tips were smaller. The overall size fit in the ear is perfect though. I can wear these for hours and hours with no problem.
PowerAMP's direct volume control is just phenomenal. I highly suggest anyone try it. It makes a good IEM great and a great IEM godlike.
I got the clear light blue ones. I did look and there was the piece of green stuff in one of the tubes in case anyone cares.
Whew! I'm sure I forgot something. Thanks for the thread. super interesting info.
[edit]Yep forgot something. As with most high end audio things, source audio matters a lot. Pretty much FLAC as a minimum for the DM6. Higher quality formats for extra special spice.
At this point i've got maybe a hundred hours of playtime on the DM6 and I have tried a bunch of tests and comparisons. They are the winners for audio of anything I have personally.
