Got my hands on a pair of AKG 501s for work. I had these some years ago and liked them. At home I have HD650s. I'm looking for a good amp for use with the 501s and an iPod using a line out. So far I'm pretty happy with the Emmeline SR-71 which I prefer slightly over the Headroom Micro. But still...

I've enjoyed my Grace 901 for a while now, but I'm interested in a SET headphone amp. Of this type what brands/models are available? The Moth 2A3 appears to be loved but as far as I know they are out of business. My headphones are the HD650s with Equinox cables.

The how do you find all the great info here? I'm looking for info on the Naim Headline headamp.

I've read enough to consider an actual purchase of the HD650s. People seem to think they are a good improvement over the HD600s. But I thought I would take one last poll. They will be used with Equinox cables. Any second opinions appreciated.

What's a good source for the AD797 op amp, and other op amps, where I don't have to buy them in quantity? Thanks.

I need a pair of closed headphones to complement my HD600s. I love the HD600s. Is there a closed headphone that is similar in performance/sound characteristics? I've tried the AT W100s and W1000s and though they are fine they are not close to the HD600s. I probably prefer the W1000s over the...

Everywhere you go on the Internet no one lists the price of the HD600 on the product page. You always have to "add to cart for price" or "call for price". I've never seen any one audio component always be priced this way so consistently. If everyone is doing it, why hide it? It's kind of stupid...

I have a single input headphone amp (I like it and want to keep it), but would like to run a CD player and a DAC into it. Basically, I need a source selector. I was using the tape out of a passive preamp, but was losing some dynamics. The fact that it was a passive preamp did not play into the...

Is there a list of all currently available headphone amps somewhere? If not, what are the options for high-end headphone amps? I have a Grace 901 that I'm very pleased with, but I'm fairly new to the headphone hobby and out of curiosity I'd like to see what else is out there. Thanks for any tips.

I was doing a search on Google for a different product. One of the result sites I visited had a pop-up ad detailing a close-out price on the HD600s. Hmmm... I know there are rumors of a newer version, the HD650, but perhaps it's coming out soon, very soon...

The new ACC, high-rez MP3, AIFF, WAV? WHat's the best option for optimum playback. I'm setting up an audio server for my home office. I really wish that Apple would include a line-out on the iPod so I can use an external DAC! Thanks.

Is the Meta42 available pre-assembled anywhere? Thanks.

I've tried the Etys, but it just didn't work for me. The in the ears thing always felt weird and the seal was difficult to get and without it the sound isn't very good. What other quality headphones are good for traveling? Smaller is better, but for the sake of high-fidelity I'll deal with...

I recently purchased a Grace 901 headphone amp based on extensive research. I have a very nice tube-based audio system, but find that since it's in the living room with the TV I don't get to enjoy it as much as I'd like. In a back room, a really nice sun-filled meditative room, I decided to set...

Hi, I'm curious about the Grace 901 headphone amp which the press seem to love, but I haven't found much here on it. Anyone out there have any experience with the Grace 901? If so, what are your impressions? It's know to be ideal for mixing where you hear everything on the recording, but that...

Hi, Now that my audio system (with speakers) is done I'm focusing on a headphone rig. What are the differences in hearing damage between open and closed headphones? I recall reading some time ago that closed headphones create increased air pressure which can stress the ear drums. Is this true...
