K701s arrived!
First time I've a "good" pair of headphones.
I usually listen music with this setup: PC's Toslink -> Modi Multibit -> KRK Rokit 6" Studio Monitors.
And this is what I learned with the AKGs:
- Test A: Modi Multibit (only DAC) -> K701: 50-70% is more than enough (volume) for me, 100% is "too loud", unless I'm listening classic music. BUT....loud frequency has a lot of distortion, specially at 100% volume. ( I assume this is because the lack of an amplifier ). Hi Freq is superb, but low to mid frequency is completely ****ty (really horrible) with just only the DAC. (It just happens in most dance/chill out songs) a lot of distortion! Unusable....
Or maybe because of the output impedance of the multibit?
- Test B: uDAC 2 (mini DAC+AMP) -> K701s (I had the uDAC-2 in a box, stored after getting the Modi Multibit): This is another story....Of course the uDAC-2 is not as good as the Multibit (as a DAC), but the (I assume "small") amplifier here..... solves all (or almost all) the distortion I was getting with the modi multibit.
(BTW, Multibit delivers MUCH MORE and defined Low Frequency than my uDAC-2 with my studio monitors, so this could be the reason in which this DAC alone, without an amp, sucks with the AKG K701s).
So, yes, I can't believe there is people who drive these phones without an amp!
What's left...is to choose to get a good amp for these headphones...My best bet is the "Fulla 2", so I can use it as an amp at home (using Multibit as a dac) and as an amp+dac (like the udac-2) when not at home. I just hope that the multibit + fulla 2 delivers better performance than the Multibit alone (without the low end distortions).
Now...if you think the Fulla 2 will be terrible for K701s...please tell me, so I can consider the Vali 2..(and forget about a portable amp+dac like the fulla is).
Why on earth are you listening to these headphones directly from the Modi? How are you even connecting them? The output impedence of the Modi is not designed for headphones at all. You aren't going to be able to hear any "quality" of the DAC component of it by doing this.
