    O2 on Li-Ion

    My O2 sounds so much better with my PS500e headphones when I use Lithium Ion batteries in it.  I'm sure it's an impedance thang.   Comments?   Anyone know how to modify this beiatch to charge lithium instead of old ****ty nm-hydride batteries.   If you do please share.  I know I can't...

    HiFiMan HE-500/Objective 2 Combo?

    I'm looking to upgrade my headphones and currently leaning toward a HiFiMan HE-500/JDS Labs Objective2 combination (or possibly Sennheiser HD650).  Any opinions on this combo?  My source would be an iPod Classic (5th gen) or possibly a PC or tablet.   I see that when ordering an Objective2...

    Amp/Dac connected to Amp

    I'm currently using the Fiio e10k. I see that the O2 amp is on sale and I'm considering picking one up in the near future.   To use the dac from the e10k, must I connect the line out (3.5mm) to the input (3.5mm) on the O2 amp? Will this bypass the amp in the e10k?

    JDS Labs O2 Amp and the FiiO E70K For the DAC

    I have a question regarding the possibility and practicality of using the JDS Labs O2 and with the E70K. Is it possible? In your opinion would it sound good? I would be using Grado SR80i's for the time being, but that is going to change in the near future. Any advice would be most appreciated.

    Cheapest Amp to Drive HD600

    I'm on a budget but want to get some Senn HD600's. I'm not so nieve to believe I don't need an amp with a little power, but I'm realistic to know I can't spend more than $200 on an amp. I currently have a Fiio E10, but would this be enough. I know Fiio is cheap so how about the new E12 or the...

    Hey everyone, I'm looking for an amplifier to power my Senn HD580's. I would like to keep the price under $150 if it's possible.

    first timer in need of guidance

    So I developed a passion for listening to high quality music. My current headphone is the Sennheiser HD555. I play all of my music out of my computer so at the moment I use a 6.3mm to 3.5mm adaptor I believe to plug it into my PC (am i losing quality?). Any music I download is strictly WAV...

    Advice on which AKG combo?

    Gentlemen! I've been reading the forums for months regarding amps, dacs, k702/q701, and k550s. I have this illogical devotion to AKG, due to my previous AKG headphones, and have trouble deciding between two different type of headphones.

    Howdy, new guy here. I'm a media nut. I love my music above all, movies are a close second and games are fun when I'm bored. I love rock and hip hop type genres.

    E7 + E9 or other?

    I currently have a FiiO E7 which I use as a DAC+Amp for my Audio-Technica M50's (even though an amp isn't really necessary on them).   I'm about to get a better pair of headphones and likely land on a DT 880 (250 ohm), DT 990 (250ohm), or HD 650. From what I understand my E7 won't be...

    Schiit or Odac for Audio Technica A900x?

    About to buy one of these guys, either the O2+ODAC or Schiit Modi/Magni.   Leaning towards Schiit because of the DC plug being on the back and price being somewhat lower. Can anyone tell me whether one combo would be better over the other for reasons that I didn't list above?

    Headphones for "electronic music" if money wasn't an issue.

    What headphones would you recommend for dance, trance, hardcore, synthpop....etc. If money wasn't an issue at all?   I often hear the term that the headphone is "too slow" for dance music. So what high end "fast headphones" would you recommend?
