    BioEQ for Rockbox is a fascinating EQ setup designed with the iRiver H140 originally in mind. The files have been given to me, FLACvest, by HiFlight. I first heard of this EQ from Dr. Xin Xin’s Cool Talk massage boards back in the day when Head-Fi was new and I was trying to figure out what the heck an operational amplifier was. I have since adapted BioEQ to sound good on the Sansa Fuze; I suspect it will do wonders for iPods and other devices.      The key feature of BioEQ is the design of the low shelf; peak filters 1, 2, and 3; high shelf filters, their Q... read more

  Hi All,   This is Zombie_X chiming in here. I have started this large information thread to help those who want a beyerdynamic headphone, but do not know what they sound like and or trying to pick one to suit their set-up. Since I have heard all of the models from 32Ohm-600Ohm's in their current production line, I thought I'd make this thread.   I thought for once and for all I would do something about the abundance of threads regarding sonic differences between all the DT770, DT880, and DT990 models at all impedances. This thread will be the most... read more

      This is a review of the 20 best headphones I currently own with some added stuff at the end.  I made the choice to review both full-size and IEMs in this comparative review.  I was originally going to make this just a wiki, but as I put more and more effort into it I started to want to share it in the forum.   Very briefly I want to clarify a few things: My home rig is the MSB Platinum DAC iii and the amps I use are the TTVJ Millett 307a as well as the Larocca PRII MKii.  I've had the fortune of also auditioning most of these headphones on the Apex... read more

Fred_Fred asked to see the method I use to make my boards. Here is the technique I use to make them:   First, you need a few basic supplies.     Transparency film Positive resist copper clad board Positive developer solution Exposure light (I built my own)   Not shown: Laser or inkjet printer (pick transparency film compatible with your printer) Plastic trays to develop and etch in One or two pieces of glass of plastic sheet (I use two sheets of glass I cut from an old window)   I also have a couple of optional items that make my life... read more

SExy0. x=Model Class y=Number of drivers   EX: Shure SE420, x=4, y=2, Thus, the headphone is in the 4th model class, and contains two drivers.   [Original Poster] In My Honest Opinion: 210 is like E3 310 is like E4 420 is like E5 530 is like E500 read more

I thought this was incredibly well said, so I'm putting it here: Quote: Originally Posted by PANGES  In my opinion, an audiophile is anyone who can appreciate sound quality. Isn't that really why we're here in the first place? To find headphones that have the particular sound quality that best suits our tastes?   By definition, the word audiophile: audio refers to sound and phile refers to love or being passionate for. So if you're an audiophile, you should just love sound or appreciate good sound quality.    I personally don't... read more

I posted this in another thread, and I notice that there are quite a few people asking about it so I thought it might warrant a thread of it's own. I wrote all of this fairly quickly, and I'm not sure I understand all of the concepts perfectly. I know there are quite a few other people here who probably understand this beter than me, so correct me if I state anything incorrectly. I found pretty much all the other info I read on the subject to be accurate, but sometimes misleading. Here is my explaination of why resistors help sound quality, and why lower impedance... read more

Lossless: Lossless means that, digitally, regardless of the format the file is stored in, there is no loss of data. The raw digital music file format types in common use are AIFF and WAV. The most common compressed digital music file format types are FLAC and ALAC.   FLAC and ALAC compress the file, much like Zip compresses a regular file, but more efficiently for audio information.   FLAC has different levels of compression, trading off file size for the amount of processing power required to compress and decompress the... read more

Here you go!! Compared to a stock phone, this mod makes them brighter and increases upper mids and treble, so its no longer overwhelmed by the bass. If you already find the FX33 too bright or harsh, you may not like this mod. If you find the FX33 muddy, bass-bloated or congested this might be a mod for you. Readers should also note that this mod is not-reversible. First you have to pull off the foam tips. Just gently pull them off with your fingers. They slide off with a little tugging. Once the foam tips are off, grasp the gray rubber tube with some pliers and pull... read more
