What kind of liquid has good electrical conductivity? I'm thinking of processing seawater to increase its conductivity. I don't want to use mercury, because I want the liquid to be transparent. It will be in a tube and used as a headphone cable. Resistance of cable is not really an issue, but...

Why do people like to listen to different music?

Well I made one. They sound amazing. I used 3" fullrange speaker drivers, but the bass is a bit strong so maybe 2" fullrange drivers would work better. The nearfield frequency response up to 3000Hz is extremely flat. Farfield measurements confirm that the treble is flat as well. It's a shame...

Fresh from the oven folks! 2-year-old N.J. canine often referred to as 'Yoda' earns regal title and $1000: http://www.msnbc.msn.com/id/19388806/

We found a big enough place for the meet now. Chuckie (TreAdidas) is hosting the meet on September 15, 2007. His address is: 5720 Lauretta Street Apt #4 San Diego, CA 92110 If you're coming please list what gear you're bringing, so that I can post it here. Of course you're not required to...

I got this mysterious tube on eBay and want to make an amp out of it, but problem is I don't know what it is, making it hard to find another one. I need to find another one in order to make an amp out of it. Anybody knows who makes this tube? The model is Silvertone 55X based on what it says on...

How many of you are head-fiers who live in San Diego? I think San Diego is a perfect place to listen to headphones. The place is always sunny, so you are happy and can enjoy headphones all the time. That is why I think there are so many head-fires in San Diego, but so few of them are active...

I went to Aaron's place today and we had a minimeet. What a blast! As you all know, the Woo6 and Doge 6210 are transformer-coupled tube amps that are known to sound tubey, unlike the Darkvoices and many OTLs I've heard which sound very solid state. They are also known to be able to drive low...

I'm looking for a transportable CD Player that can also play MP3s (either burned onto the CD or from a memory stick), and output the digital signal to my DAC. I'm hoping to just buy it commercially for a decent price. If not, I'll have to get a laptop, which is expensive. Or modify a car...

What are the biggest headphones you can get for cheap? I'm not actually going to listen to them, but throw out the drivers to add in my own.

According to this site: http://www.musicaldesign.com Two months ago they have already ceased production of Blackgates. I am sad, because I've always wanted to try them in various applications. I've never tried the N series, or the WKZ series for tube amps. ARGH! Someone should buy the rights to...

Hi, I'm looking for the smallest 0.22uF film capacitor for a high frequency filter. Paper in oil is also fine. It needs to be rated for at least 50V but not too high or they get too big. Most of the good caps I see are rated at 400V or more, so they are overkill, which is fine except that they...

Anyone in SoCal with Ultrasones I can listen to? I'm really curious about them, and how they compare to the other headphones I've heard. In turn, you might also be interested in hearing my equipment I've collected over the years.

What headphone has the most bass output and slam without distorting or clipping? I'm looking for open full-sized headphones, with lots and lots of bass output. I'm not really going to listen to them much, but experiment with their drivers, and performs tests on them. They may not survive, since...

Does anyone make a single-ended direct-heated triode tube amp (SE-DHT) for headphones? One that has zero background hum? It's OK if the amp is designed for speakers, because so long as there is no hum, it can easily be adapted for headphones. I would prefer 2A3 or 45 as tubes. It must have that...

Are there any discrete buffer designs for balanced sources? Instead of using an amp I would prefer a buffer since balanced sources already have a high voltage. I don't want opamps I want discrete. Readily available PCBs would also be nice.

The X-Fi is without question the best gaming card, but the sound quality is average at best. As someone who is used to high end external DACs with discrete output, to me the sound quality of the X-Fi can be best described as "low-fi". But rest assured X-Fi owners, we can make it far better! I...

I just made a thread in the DIY section on recabling the AKG K701. http://www.head-fi.org/forums/showthread.php?p=2762660

People say that the AKG K701 headphone lacks bass, but the reason is because they are not using the right amp. This headphone needs a lot of power, and will impress you with her might when you make her happy. Many people who have heard a balanced amp never go back to the single-ended version...

... The AKG K701's!!!! Just letting you guys know...

Gaming sound is very important to me. Anyone who has experienced gaming audio nirvana will know that it is every bit as powerful as musical nirvana. I'm looking for a headphone for playing computer games, like DOOM and old fantasy RPGs. My requirements are huge soundstage and incredible detail...

has anyone ever converted the HD650 to an open design? i'm just curious about your impressions. i've searched the forums and no one has ever posted anything about this, but i'm sure it's been done. open (infinite baffle) always sounded more transparent to me than closed (sealed). and also it...

I know headphones can be used as microphones, but what else are they good for?
