But it seems that he/she has some intension and I don't see what the community can benefit from such behaviors. So I'd like to say to be aware yourself. 
Good point.
But I am afraid you are talking about me because I am the only one right now still talking about what's going on in the Korean M community.
And I wont have a problem if you try to correct my information, if that really is misinformation, because I could be wrong when I am summarising what has been posted in M cafe. In that case you are more than welcome.
And I can assure that I dont have hidden ultimate distorted motivation, if I had one that would be 'wanting to enjoy great daps without much fuss(price, ui, etc) I hope that would not a wicked motivation for you.
I am ordinary busy working man if not as busy as you, headphones, daps, and amps are just a little hobby for me.

Thank you oh.

Well, frankly speaking I have no idea how it works, because every information about it is not directly coming from calyx but from the admin of calyx and persons having close relationship with calyx.
And probably most of people who have some knowledge on how a headphone amp works would be against the idea that zero ohm causes the noise because if that is true some part of amp industry shoud have collapsed some time ago.
But that 'zero ohm story' is related by M cafe member, not directly by calyx, so I guess we have to wait official expanation.
And as far as I know, there are no reports from foreign users experincing the noise,so may be this noise problem is only happened in the first korean batch and I hope it stays that way.

This is saturday and it rains heavily so I decided not to go out. A couple of snapshots of the upcoming updated firmware preceded the photo of plug in the posting at the Korean M naver cafe where the photo of plug appeared.

 

설정 = Configuration

임피던스 매칭 = Impedance Matching

저 =  Low / 중 = Mid / 고 = High

퀵뷰로 꺼내기 = Extract to Quickview

확인 = Confirm

 

 

라이브러리 메뉴 = Library Menu

 

원하는 뷰를 .... = Tap menus you want to edit the library menu

앨범 / 아티스트 / 폴더 / 재생목록 / 트랙 = Album / Artist / Folder / Playlist / Track

확인 = Confirm

Thanks for sharing! Does that means three levels of impedance matching from 70ohm to 240ohm or more? Any idea how the impedance match is achieved via software? Cheers!

7-24+

 

Unless they magically threw in some feedback resistors and relays it's likely pre-attenuation in the 9018k2m dac.

7Ω to 24Ω or more. M's voltage swing can be insufficient to drive 240 ohm cans I think. I'm not sure what the menu calls is same to impedance matching of transmission lines. But it is said that it will optimize sound depending on the impedance of the connected phones.

I'm guessing it's gain levels.  It does say, low, med, high.  It's basically gain.

Oops viewing from the phone I misread it as 70-240 while it's 7Ω to 24Ω+... lol...

See, I guess I'd need to go get another extended demo with my IEMs again and see how the different gain setting pairs.  If it is gain I'm under the impression this has more to do with the hiss issue some reported than any thing else... (e.g. lowering gain for ultra-sensitive IEMs to avoid picking up background hiss)

Once more with feeling...

 

7-16

16-24

24+

 

Which is just an odd break down..

it is indeed. Given that all my IEMs are 16 ohms, there is no clear guidance on which setting is best. Probably the lowest.

Got a chance to demo the M at Jaben (Beijing) today. 

 

The unit was not burned in, in fact I was the first one to audition it (it's sealed in the box). Firmware was version 0.6 which I think it's the latest.

 

Headphones: Mainly JH Roxanne (customs) and briefly with SE846.

 

Other audiophile DAPs I've owned recently: X5 (current) and HM901 w/balanced card (sold not too long ago).

 

Build

Nice and solid like the iPhone 4/4s but very bulky. The screen was probably the best out there. Volume slider was quite stiff but I was able to fine-tune to the desired volume.

 

M >> 901 > X5

 

User Interface

Navigation wasn't the most intuitive but otherwise the UI was adequate. An example: to go back to the track listing from "Now Playing" you would think that there would be a back button, but no, one would have to swipe to go back. Operations were mostly smooth except there's a tiny delay before user inputs took effect (also applies to the volume slider).

 

Library scan was quite fast and wouldn't slow down the device. I brought two cards with me and it had no problem reading them (with both FLAC and DSF files).

 

M > X5 > 901

 

Sound

Calyx must have reworked the audio engine in 0.6 because the sound signature now was quite neutral (it was described by some head-fi'ers who heard the demo versions as thick and warm)

 

Bass: Well extended and more linear than the X5, whose PO had an obvious mid-bass hump while the M had more rumble in the sub-bass.

 

Treble: I'm not a fan of treble so this is probably the area I pay the least attention to, but I would say the Roxanne was the least dark sounding out of the M

 

Mids: Neutral but not thin, not in-your-face kind of mids, felt a bit distant sounding . The other 2 DAPs sounded intimate and warmer. The 901 had the fullest mids.

 

Noise: I heard no noise with my Roxanne (very sensitive: 119dB @ 1mW) , and felt the M has more depth in the sound and was more transparent than the X5 (and possibly the 901), which I think can be attributed to the very black background and low noise floor. Impressive.

 

Detail retrieval: M > X5. My memory could be at fault here so take it with a grain of salt, but I would also say the M > 901.

 

Soundstaging/imaging: The M was the more spacious one and had the sharper imaging while the X5 felt more intimate and less defined.

 

The M worked superbly with acoustic music and IMO had the best synergy with the Roxanne (which is considered warm, thick and even dark by some) out of the three DAPs. However vocal lovers might still find the 901 more engaging and musical.

 

 

 

 

 

I was impressed by the M. I am now seriously considering buying one but will probably wait until folder browsing is available (and after trying out the Cowon P1 and the AK100/120II :biggrin:).

Sounds like it's coming around.:smile: If only it weren't so big.

Does anyone have the exact dimensions of this device?

Thanks for this.

 

I too am waiting for the next firmware. Then I may have to visit Beijing and listen. Perhaps meet (for some) Peking Duck?   :smile:
