    Fiio E17?

    I've been looking into the Dennon d7000's or the Audez LCD-2's and I would like to know if the Fiio E17 amp would work well with them? I would also appreciate it if you could recommend other portable amps (<$250). I will also be using an iPhone.

    Upgrade to Fiio E10

    Hey guys,   I'm looking for a usb DAC/amp that is an upgrade to the E10 that I can listen to music on my computer.  Ive been reading through a lot of threads but not really sure what to get.  Preferrably under $200, less is better.  Thanks.

    Amp for DT990 Pro 250?

    So far I've been looking at something like the E9 + E17 or E11 + E17 or something like that. Fiio is all I really know in amps and I haven't really found much on how they work with Beyerdynamic. I'm also looking for it to be portable. It doesn't need to be pocket sized, I'm not always on...

    c421 vs O2 - home amp?

    I plan to use an amp with my Miracle. It'll probably be paired with the DX100 if I can get one. I've heard of lots of good things about the Objective 2 / DX100 pairing, but how does the c421 compare? Its strictly for home use - I won't carry and amp + a brick for portable use, so disregard...

    JDSLabs C421 Preorder is live...

    Two opamp choices available - one for higher impedance cans, one for lower (JDS states the one suited for higher impedance cans emphasizes bass over transparancy).  It doesn't look like they can be rolled.   http://blog.jdslabs.com/?p=179     According to the blog entry, only 95 amps...

    Small Objective 2 Review

      To Start…   There are a lot of amps out there that use exotic topologies and expensive parts.  Even “budget” amplifiers try to get in on this game.  Too often, that practice fails and you end up with a “transparent” amp that is anything but.  Or an amp is made that trades reliability for...

    Headphones for female vocals that span many genres? (Up to ~$400) [Paired with O2/ODAC]

    Hello Head-Fi! I intend on getting the O2/ODAC combo and spending $250-$300 on headphones. My initial choice was the DT880, but I've heard that it has recessed upper-mids that make female artists sound a little less than stellar. I'm very unfamiliar with audio and its qualities, so is there...

    Headphone amp vs AV receiver headphone output

    hope this isn't rehashed, couldn't find a similar topic.   i'm wondering if headphone amps are actually better at powering good headphones (something like Sennheiser HD 700) than a mid to upper range AV receiver would. i have a Denon 3313ci which costs a little over $1,000. however, a...

    Absolutely Clueless - Want Advice!

    I bought a pair of Audio Technica ATH-AD700's a few months ago and absolutely love them. The sound is better than any headphones I have listened to in my life. But now I am reading about amps, and that they improve the sound? Is it worth buying an amp for these headphones? Will the improvement...

    HiFiMan HE-500/Objective 2 Combo?

    Hi everyone, can you guys help me decide a combo of headphone with amp/dac with the budget of $700? Most of the time I listen to J-Pop and classical music. A little bit rock sometimes, but not much. I like something that is detailed and has good imaging. Thanks.   Edit: my source is the...

    HD600 Amp

    Just bought an HD600 and am looking for amp recommendations. I would like to keep the cost below $200. I looked at Little Dot II or III and the O2 as possibilities so far. Are either of those more preferable or is another option better?   Thanks in advance for any help.

    Which has the better soundstage, AKG K702/Q701 or DT990?

    I'm considering buying either of these headphones and was wondering which one has the better soundstage. I'm also curious to know which one is more comfortable. Based on what I've read, I'm tending to think that the DT990 is more comfortable but I could be wrong. Also, could the K702/Q701 or the...
