Levanter makes good points but in this instance i have to agree with skerry and waynes.I recently auditioned the a15 which has 10mw if i'm not mistaken with ie800 just to see if it can sufficiently drive them and saddly it cannot.At 30 volume cap the sound was just about loud to enjoy music like classical but not enough for edtm.Add to the fact that there are lower volume recorded albums and i'm not sure if the additional 5mw of zx2 can make a difference.Of course armature iems are a different matter.
The volume output is simply too low and i've already read some forums that people who have ie800 want to pair it with zx2.Hope they won't be dissapointed by lack of power.
Not sure about the A15 pairing, but i've seen people happily pairing their IE800 with ZX2 with no problems. Then again, different people have different preference/anatomy to music volumes.
I totally understand your point, @Levanter , but out of curiosity, why are you promoting zx2 in fiio x7 thread?
i understand that you really liked zx2, but i do not understand why would you say good things about it here. i belive you when you say that for you it sounds extremely good, but it cannot sound good for everybody.
use a little of my logic, when i bought my x5, the x3 was a step up from cowon j3, but x5 was much better. not due to power, but strictly speaking SQ.
i am having high hopes for x7 as it seems like it is going to have a very good SQ, but i would never consider a sony, specially the zx2. there are more than one reason, but i simply would not. at 1200$ i think i can get better. considering the price point of fiio x7, i can safely buy an x7 + ie800 for that money, or even better an x5+e12a+ie800, or x5+ultrasone signature dj.
i am sure that there will be as many people liking the zx2 as there are liking AK daps, but both target the same marketplace, while fiio is less expensive.
In my auditions i really liked fiio products better, but this is me, i cannot make an objective statement like this, but in my subjective opinion this is how i feel.
for getting something that is better than my actual x5, i would either upgrade to x5II, or x7. i like price/performance ratio, and SQ that fiio products are offering.
The only and absolutley only other thing that includes a DAC that i had heared to date that beats the actual x5 is hugo. the rest were side-grades, some downgrades, but it is subjective. I am yet to hear ifi products, but i also have high hopes from them.
It is good that we all hear differently, and we all have different opinions. This means that there will be different companies making different products for each one of us!
I am not promoting, i'm being objective. I defend products against ridiculous claims and similarly i take offence with hyped up exaggerated claims e.g. Layla sounding bigger than TOTL full size headphones. I've seen that ridiculous claims a few times in the Layla thread which i found ludicrous.
It's find if you think ZX2 does not have enough power to drive "certain/few" IEMs, but claiming they can't drive "most" IEMs is something i have to make a stand against.
