Is there any chance the ROC can be compared with little Dot MK VI?

I'm very interested in this as well. I'm trying to decide between both of these for my christmas present next month.

Still waiting for the comparison... patiently...

In terms of design and sound quality is there any different in (2) 3 pins balance and (1) 4 pin balance?

SQ wise - no difference.

4 pin design is more elegant, cheaper and easier to do.

IMO, two 3 pin XLR headphone cable design is just for those who have only such balanced connectors on their balanced headamp... but even then you can easily scrap up a 2x 3 pin male XLR to 4 pin female XLR adapter.

Has there been a comparison to the Phoenix yet? I'm really stuck between the two as a next upgrade with the DV 337SE. I'd like to go outside Kingwa's selection a little, but it looks so promising for under $1000. I'm pretty sure I'll get the MK3 anyway.

Which or what MK3?

You really need a balanced source and balanced headphones for the Roc and Phoenix. Kind of wasting some of the benefits without it.

That's why I'm getting a balanced DAC to go with it. I will be borrowing one from a friend to try out.

Kingwa said that both of them sound nearly the same except for subtle differences.

So I assume unless you have the very high end Dragon cables with PS1000s or D7000s, you won't be able to tell the difference reproduction wise?

I'll either get the D2000 or HF2s/325is and get aftermarkets. I'm just not sure on the power and interconnects yet, so I have to research those more.

But if I go balanced, I'm not sure which balanced DAC to check out. I really want to hear that "B" mode MK3 though.

These ideas aren't final though. I'll be researching for awhile yet.

Dragon? The Moon Audio cables, right? Never heard any of them so I can not comment. From their looks they look very stiff from the Techflex on them.

Zombie_X,
a couple of questions for you:
1) have you ever tried the ROC with high impedance phones? Do you think it can handle 600 ohm cans?
2) any hiss or hum using low impedance cans such as the K701? And what about the volume? can you tune it right with those cans, or is it too loud?
Thanks

He has the 600 Ohm Beyerdynamic DT880s, so I presume it will drive them just fine. As for hiss on the K701, I don't know, but that'd be odd as the K701 aren't very efficient.

I remembered something about the DT880, but I couldn't find the post.
Thanks!

You'll have 0,7 W RMS in class A at 600 Ohm. Judging on the way it enslaves HD600 (300 Ohm), I'd say it will. Especially if you drive your 600 Ohms balanced.

With W1000 (which are more sensitive and lower impedance than K701) and paused player you barely hear some kind of buzz on two final steps (source+amp noise, step 22 and 23). But this level would be insanely loud and would probably rip apart the drivers in "normal" music listening.

Most usable levels depend on the listener's preferences. Mine hover around 11-12 for K701 and 9-10 for W1000, both in balanced mode. In SE mode add "hour or two" to those mentioned ("just" 2 of 4 channels are used in SE mode).

It is worth mentioning that, when ordering Roc (or even later if you are able to swap the attenuator by yourself), you can ask for "lowered gain setting" of the 23 steps on the 4 channel attenuator.
