I was introduced to Fiio when I purchased an E17 Alpen six months ago.  Since then the E17 has been in daily use on my desktop and in my pocket.  I think it's one of the best values in audio.  So I was very excited to get a chance to review their new guitar headphone amp, the G1.    ...

I've used both the E17 and the O2 for my k702s. I think you'd be happy with either one. If you need a DAC it's hard to beat the E17 at that price. If not, the O2 really does a fine job driving the AKGs. It's a step above the E17. I've stopped looking for an amp for those cans.

I am very happy with my JDS Labs O2/K702 combination--great soundstage, high quality bass, tons of detail.  For the price, if you don't like it, you're not out much.  I was wary of this combo, because they are both known to be analytical pieces, but IMO the O2 makes the K702s sound as they were...

I compared them side by side through the same high quality source and I thought the 325is was easily worth the extra money, build quality and sound quality.

I have both the E17 and the O2.  The E17 is, IMO, an excellent value for the money. For several months I used it to drive my K702s at my desk, and it did a very nice job.  With the gain set at +6, I was able to get a very decent sound out of those phones. I was quite surprised by the quality...

I have some fat bottle 6fd7s in there now, which are higher gain, but I don't like the way they drive my k702s. The amp sounds fantastic with my Grados. I'm looking for something to compliment them. I should probably consider the 250 ohm version, but they are more expensive right now.

I have a WA6 with some excellent tubes in it and I don't find it to be an amp with a lot of gain. I am interested in the DT880s, especially the 600 ohm version, but I am afraid the amp won't drive them well. Do you get enough volume and quality bass with the Woo/880 pairing?

I have 160GB of Apple lossless on my iPod and it works perfectly with long battery life. I listen to mostly jazz and never have any skipping.. You can hear the difference. XLD is a simple, fast program for converting.

Quote:   I love my WA6 with the Grados.  That's my prime headphone station.  Being an old guitar player who loves Fender Tweed amps, I have had a great deal of fun rolling tubes through that amp.  However I never liked it with my K702s.  It was fine for acoustic, classical and chamber...

I am interested in your thoughts about the E17 vs the O2 when paired with the AKGs. The O2 is quite attractive at its price.

I have been enjoying my K702s in my desktop setup with the E17. I've been surprised how well the Fiio drives them. Question: how much better do your AKGs sound through the O2 or whatever other amp you are using?

Nice guys really cool rigs :)

My Fiio E17 drives my K702s very well.

Quote: I've had my E17 for about 2 wks.  I love it at the desk with my K702s; +6 on the gain and +2 on the bass sounds very nice.  I am thinking about a desktop amp, perhaps the O2 or the M-Stage.  I haven't tried my SE215s w/o the Fiio hooked up to my iPod Classic (via LOD).  I just got...

I'm curious about how that E17/O2 combo works out for you.  I'm contemplating that for my desk to drive my K702s.
