I'd be curios to see it to validate [or disprove] my findings :D

My guess would be the same as the 601, maybe with slightly more bass.

Graphs don't show sibilance or harshness, I guess... They don't seem to be that way as far as the graphs read, but I can hear some.

Of course graphs show sibilance and harshness...

Yes they do but I don't see it with the K601...
I was being sarcastic...

Sarcasm rarely comes across on Head-Fi because of the things some people here believe, sorry if I misunderstood you.

Interestingly, I haven't had any issues with sibilance or harshness from my K612 pros.

Yeah I get that wink.gif
Yeah the sibilance thing is strange... Maybe I'm just prone to it or maybe it's the Mstage.
I'm using the LM4562 but I'll be replacing it with a different one.
I'll also see how other headphones fare.

Have you experienced much changes with changing opamps? I have only tinkered with tubes, and rolling tubes can drastically change the sound. Some tubes are much better sounding than others it can bring the amp to the next tier sonically.

The difference between op-amps is not nearly as drastic as between tubes. At least so far it hasn't been. I'll see with the LME49710HA...

I have found some tubes don't change the sound much from other tubes, but others change the sound drastically. Maybe it's a similar thing with opamps.

Hope so :]

Yea. Btw the sibilance can be caused by the dac rather than the amplifier.

Yeah, it's a basic PCM1793 DAC based on an XMOS chip [it's the Mstage's own improved DAC module].

But it's been reported that this DAC module is pretty good [it reportedly competes with <500$ DACs]

I wouldn't know though :D And I'll try the different op-amps first to see.

The dac just could be a little bright for the K612. I have messed around with the sources and the results are quite noticeable. Switching from my soundcard to my EF2A dac is drastic. The K612 with the EF2A hooked up to the soundcard is dark sounding, has a black background, more warmth and bass presence, better defined imaging and larger soundstage, and more tactility to the bass and midrange. The EF2A's built-in dac is brighter, more sparkly, and more aggressive, the soundstage is a little more compressed, and the background isn't black anymore. I don't know how the m-stages dac sound, haven't heard it before.

Sounds like the Mstage DAC has a similar bright characteristic as well.

It sounds absolutely fabulous and not bright at all with instrumental music, until you add vocals in. I believe the headphone is partially to blame too though, I hope a different op-amp will help a bit or maybe the 560 will just sound absolutely fine...

I'll see :popcorn:

It likely does. The headphone is likely partially to blame, but it's the least sibilant headphone I own. It's more of an inherent issue with most dynamics, a somewhat metallic sound to vocals to varying degrees.
