Interesting. Say price isn't a factor here, which is more powerful, the O2 or the Fiio E7 + E9?

If by "powerful" you're talking about actual electric power, the E9 is more powerful than the O2 into lower-impedance loads. You can see the data for yourself on the O2 designer's blog. However, into higher-impedance loads including your headphones, both are about the same, limited to around 7V. So they're about equally as powerful into most headphones that need a lot of voltage. E9 of course has no batteries, and the O2 can't play quite as loud on battery as on AC power. Think like 3-4 dB different, which is not a huge amount perceptually.

O2 is considerably more powerful than the E7, if you wanted to use something away from mains power.

But unless you're currently maxing out the volume or getting close, you don't actually need any more power though. Sometimes I think there's some kind of confusion regarding a subjectively "powerful" sound, whatever that means, and actually being able to output more electrical power. What is it you really mean by "power"?

The actual sound of the O2 should be better, but quite likely there's no noticeable difference compared to the E9 for driving high-impedance headphones.

Sold my Ultrasone PRO900s, bought a pair of HD600s with a Moon Audio Blue Dragon v3 cable.

I've never been one to believe the cabling hype, so I'm really excited to A/B the stock cable to this stupidly expensive $200 cable, and see if there are, in fact, any differences.

That makes sense. By power I mean how well they'll drive my 250 ohm headphones. How about the O2 vs the e17? The thing that I don't like about the O2 is that it doesn't have DAC. Will my onboard dac hold the O2 down?

If I wasn't such a nancy and scared to screw up my cans I'd try it tongue.gif

The O2 will be much better than the E17, the ODAC will be released soon which will work very well with the O2

I see. How much will the DAC go for?

This is good advice.

As far as cost, NwAvGuy's last update states that the ODAC is due to come in at under ~$100 assembled and ready to install.

EDIT: I just read through your earlier threads, I use an e9 myself and enjoy it but I'll be building (a whole batch if all goes as planned) an o2 for myself and some others shortly.
