I want to re-terminate my grado sr325is but I don't want to deal with opening the cups and all that, so I figured I could cut a few inches off the existing cable and just put a new plug on it. However, I don't know how the stock cable is wired and how the wires are colored if at all. If you...

I need something pretty pocketable for when I go to the library and such to study (college kid here) but will still drive the headphones. I will be using one of two set ups.... Code: iPod Classic -> DIY LOD -> (T4, no DAC) -> Alien Ears IEM -> (Icon, DAC) -> Alien Ears IEM or Macbook Pro...

what would you feel is the best portable amp for the D2000's? I will be using my custom IEM's for my 'on-the-street' but for listening/studying in the library/coffee house/etc I plan on using full cans so I need something portable (can safely be put in backpack or pocket). If possible, around...

I am building a new portable amp for use with my new custom IEM's (Hearyourself/Alien Ears) as well as my soon-to-be-shipped Denon AH-D2000's but I hate wallwarts and the fact I am in college and will ALWAYS have my laptop with me, I figured the amp should be able to be powered as well as...

I'm playing around in Eagle, making a CMoy layout I may or may not build (but that's beside the point) and looking at the schematic on Tangent's site, D1 is a 1N5822 rectifier (also, CANNOT find a part library for that part, anyone know of one?) but in the bill of materials, D1 is the power...

I'm planning on either buying and then modding a new pair of Grados or re-doing my current pair (woodied but just ordered the cups from a supplier) because I am not a fan of the build quality or the impact on the sound. I was wondering if anyone knows of a place that gives information on a...

I have noticed (although increasing seemingly exponentially lately) that members, generally newcomers, are falling into one or more forum death traps. These behaviors are ones that lead to the deletion, locking, or general stalemating of an otherwise potentially helpful thread. I know this...

Hello, I'm designing a portable amp based on AMB's Mini3 but so far I am unable to find a few parts for Eagle, namely ANY of the opamps (OPA690ID, LMH6642MA, AD8397ARDZ, LMH6643MA). Has anyone else found a source for them? I am aware I can make them but there is no sense in reinventing the wheel.

Hi, I'm going off to college next year and seeing as how the city I'll be living in is the live music capitol (Austin, TX for all you uncultured people ) I think i need a decent portable rig! I still want the circum-aural vibe, they don't have to be full cans but the noise reduction and SQ...

I am buying my cousin a set of headphones for recording guitar on his new Mac I got him but he will also be using them for recreational listening. He's pretty new to the HiFi stuff but I want to set him off right. I'm hoping to spend between $100 - $150 because the Mac was a lot. Anyway, they...

I'm getting some Grados for my girlfriend for her birthday, but I want to know, where did you get your Grados from? I may pick up son SR-60's for myself, so a place with a nice variety of them would be nice. I know Amazon sells some but I've had a few troubles with them in the past. Most...

Hi, I'm new around here but have been building guitar amps and other general electronics for a few years now. Recently I got into the hi-fi audio scene but being a DIY-er at heart a pincher at wallet, I want to build a headphone amp. I'll be using my recently purchased iPhone (same internals...

I'm looking for a low cost headphone amp and have heard pretty good things about the FiiO's. I can find the E3 and the E5 but the E5 is much more expensive (relatively at least, only $15 more before shipping) and I was wondering what the major differences were and if I should get the more...
