Centrance Hifi-M8 and Hifi-M8 LX (8 versions!) impressions thread - Page 37

post #541 of 1319
Rush 2112 (fairly quiet recording)
1964 ears quads, iPod classic to HIFI-M8, lowest gain


Loudness wars winner recording, same setup



Pictures came out a little blurry. The volume pot is above any channel imbalance. This particular volume pot is pretty good. Enough adjustment to fine tune even way down there in the travel, though you need bit of a fine touch. Not too bad, as the know is a bit stiff - really just about right as to turning resistance.

Hiss - barely audible with player on pause. I could not detect any hiss at all with music playing. For my personal use, this is just fine. If I used IEM's all the time, I might get the mod, but I don't so I prefer the HIFI-M8 as delivered.

More notes - non scientific "comfortable" listening volume for me. I listen pretty quietly.

Edit for a random report - Pandora 256 kbs files sound pretty darned good from the M8. Still 256 kbs files, but quite good.

That's a very quiet recording!

GREAT pic for that aspect of your eval

Al true. 6dB less. No SQ degradation we can measure or hear.

Not until we move into more impressive digs. It's a small place with people running around, trying to get stuff done. Not glamorous at all, but productive. We like productive :)

Following up on an earlier post, I had mentioned that the M8 / ipod combo was disappointing with the headphones I have -- LCD-2 and UE10.  I thought that while the M8 had powerful, rich sound, it didn't really play well with my cans and so there may be an issue with synergy.  

 

I can now confirm that's pretty much the case.

 

Going through reviews in this thread, I read with interest positive impressions with Mad Dogs.  What's this?  Dan is 20 miles south of me here in San Diego.  That's just too close, too much temptation, so there went $300 and a couple gallons of gas.

 

Such a better pairing.  So here's how things funnily lay out...

 

The M8's darker tone pairs very well with the crispness of the Mad Dog's sound.  As mentioned earlier, the M8 with my UE10 and LCD-2 sounded too dark / held back vs. those cans with the Dragonfly, which has a much open, airier sound.

 

So as you might expect, pairing the Dragonfly with the Mad Dogs is too much, too bright, shrill and lean.  

 

The Mad Dogs with the M8 have much better balance, life, musicality, and synergy that was missing with my other cans.  I'm now very happy with this pairing and more than just a bit relieved.

 

All that said, I need to further optimize this system.  I bought the SE Mad Dog and now realize that these cans are hard to drive.  I'm not quite satisfied with the low-punch the M8 is putting out, even at highest gain.  I need to try balanced MDs.  Ultimately, the MD may not have the low-freq I crave, so we'll see.

 

Other notes:

 

-  It was cool to see the MrSpeaker assembly room, with Fostex cans laid out and being modded to MDs.  Even more awesome was seeing the red Alpha Dog cups being 3D printed.  Go small-biz USA manufacturing! 

 

- My M8 unit is headed back to Centrance this Friday so that Michael and his team can remedy a few issues with the battery indicator as well as with ipod / M8 sound-dropping.

Just realized that my treble switch has the same problem that other users have been experiencing recently.

I won't need it yet but if I do I'm ready to mail it back I guess..

post #547 of 1319

I don't think the increase in SPL while having the switch in between positions is a problem. I too have the increase in volume when the switch is at 1.5 and 2.5 but the switch works as intended when its in its proper positions.

I hope Mr Goodman will clarify.

Ah, I see. So the increase in SPL isn't a problem after all.

My switch will do that as well, if I get it stuck between positions.  As to the tone shaping itself - very subtle with the treble, more noticeable with the bass switch.  With the treble, the easiest way for me to pick it out is the "tizz" in cymbals and hi-hat.  If you listen for that, it is subtle but obvious to me.  I've stated before that I had low expectations for the switches, because I thought they'd be a pretty massive effect.  It turns out that they are very well done, with tight focus in just the necessary frequency band.  They are a winner to me.

Listening to my Hifi-M8 this morning whilst commuting.
Super sweet.
Changed the pads on my ATH-ESW11 to a more low rider set now the lows are more lush and deep.

Are there any analogue inputs for the M8?

Thank you. Glad you like it. It took about 6 months of fine-tuning to get the frequency shaping just right. We had a number of throw-away prototypes until finally it was just "there".

 

So I hear you -- this crowd needs well-designed stuff. Can't get away with a cheap consumer feel :)

HiFi-M8 does not have analog inputs. It's designed to work with computer or iPhone as a source.

Thanks for letting me know--that's what I thought, but I just wanted to make sure before ordering another amp for home use.

Would like to report that the M8 works flawlessly on my iPad 4 through lightning with iOS 7.

The native music player, Spotify and Deezer work fine and the volume control is disabled when the M8 is connected.

It should be the same with the iPhone 5 and iPad mini.
