Does anyone know where either periodic audio or campfire source their microdrivers/dynamic drivers?

I thought it would be interesting to get some feedback on my thought process for creating REW convolution filters for headphones. Feel free to tell me the whole idea is nonsense as I'm no audio expert!   Anyway, as many folks have noticed headphones have terrible FR response, and I've been...

I was curious as to whether anyone has used digital room correction (DRC) software (e.g. Dirac, Audiolens, Acourate, REW) to develop custom curves for IEMs? Given a calibrated microphone and a coupler for the IEMs it seems to me that it would be a fairly straightforward process (at least in...

I'm trying to find an all-in-1 headphone amp, DAC and pre-amp (or just a dac/amp with balanced outputs that can be muted) for my office setup. My current setup runs PC -> Focusrite 2i4 -> powered monitors and a range of headphones (LCD-3, Fostex TH-X00, Senn HD580, Shure SRH 840, and Weston W40s...

Got bored and decided to conduct some very unscientific tests.  Test 1 was to see if my hearing is shot so I listened to some test tones to determine whether I could hear high frequency sounds.  I passed that at 17K.  That's not really great but then again I'm not a teenager these days so I'm...

I was just curious if anyone has ever used a program such as Audio DiffMaker to check for differences between the output of various DACs.  Something like EMU 0404 USB vs Bechmark Dac1?  For those who have no idea what Audio DiffMaker is just click the link.  In short it basically makes two audio...

I've been out of the loop for a bit so hopefully some folks can help me out here, and yes I've poked through some threads for ideas =). I'm looking for a closed can to listen to while at work. For some background, I'm currently using a Headroom Total BitHead while at work powered via USB...

Is this possible to do with out too much work instead of sending them back in for repair?

Too much for a stepped attenuator for a headphone amp or will it work? If it matters I'm using Senns w/ the amp (going to build either a ppa or b22). Anyhow if anyone is interested in a cheap attenutor there is a pretty cool one on glass wares for $40ish dollars. You can obviously change out the...

Lot of 5 power supplies, three irons and three stands, and 5 power cords. Lets hope at least one of em works well. The price was right at least!

Thinking about using this for a source as my craptastic 10 yr old Samsung DVD seems to be on its last legs. Anyone know anything about it? Good, bad or ugly? I think my other options is the Lite CD-15 but I can't find one review of that unit anywhere reputable. All input is welcome...

I apologize up front if this is not the appropriate place fo this post. So i picked up a pair of e2c's mainly for work (keep my noisy coworkers from bugging me) and the gym. And here is my problem, when i first attached them to my pc i was picking up a great deal of interference (you could...
