I know there's a DIY section but not many people visit there. Are there any mid-high end amp kits or amp schematics between $200-600? I'm looking for a new amp for my HD 650(and possibly a LCD-2 in the future).    Actually, here's the most important question...Are DIY amps better(in terms of...

Come on guys lets be honest, what looks better? HD 555 grill on a 515, and 515 on a 555.           

Pretty sure this thread has been made 1000 times, but I'm still going to do it.    Why do some people prefer tubes over solid state amps or hybrids? Is it because of sound signature or are there any other technical advantages?

I saw this on Walmart    http://www.walmart.com/ip/Audio-Technica-Open-Air-Dynamic-Headphones-With-Titanium-Alloy-Cord/10980656   It looks like a different colored AD700 with "titanium alloy cord" and magnesium frame(regular AD700 is plastic frame).   Anyone have them?

I bought a semi-broken HD 650 headband to go with my HD 650 drivers a few months ago. There was an existing crack(around half way) in the headband when I bought it, but still held together. However, I broke them today.  I've tried numerous ways to repair(plastic epoxy, super glue, Gorilla glue...

I seriously don't much much about amps(other than how they function) and I'm beginning to think what's limiting my adventure on finding audio nirvana is my amp/DAC. I currently use the E7+E9 and I'm looking for an amp that would be great with my headphone collection(look at my signature). The...

I'm 16 right now and I've been considering custom IEMs for a while now, however I am afraid I might have to get a refit/remold every year or so. Does anyone have experience or have knowledge with ear growth, IEM fit, etc.?

I just read this on Stefan AudioArt's site    Quote: http://stefanaudioart.com/Equinox%20HEADPHONE%20Cable%20Tips%20.html     This is very interesting since everywhere I looked, people said the HD 650 cable is better. I just received my HD 650 cable today (I've been using a HD...

I bought a 75 ohms impedance adapter for my ER-4P to S but I sold my Etymotic the next day because I was in need of cash. I was toying with the 75 impedance adapter by plugging in with random headphones and usually it's all bad results but with the HD 555, it's different.    With the...

Many high end cans, namely LCD-2, HD 800, HE-6, STAX, etc. costs $1000+   At what point are headphones not justifiable for their price tag because of the small little detail difference offered?   For example a $600 headphone is not going to be better two times better than a $300 one, but...

Edit: Apparently I had a defective M50 that had very recessed mids. This mod does not apply anymore.  The M50's recessed mids always annoyed me because most of my cans have decent to smooth midranges. The M50's mid just didn't do it for me.    Here's a way to make it less recessed.  ...

Why does my SR80 (not i) have a pink driver on the right side and a regular driver on the left? I'll take some pics tomorrow when I have time. I am pretty sure I don't have eye problems.

What's the highest frequency that is audible to you at a reasonable level?     I think I screwed up my ear...I'm 16 and the highest I can hear is around 14~15k

  Got 13 here, all came with the headphones and IEMs I bought. 

I need a versatile amp for around $150 to $200. The cans I use are in my signature, and I might plan to get a pair of high-end headphone soon(DT880, D2000, or FA-011).

The earpad on my MDR-F1 is beat up and ripped like crazy and a pair costs $60. I don't really want to spend that amount since IMO, that's a ripoff. The earpad measures in 100mm diameter (outside) and ~84cm inside. Are there any pads around that size? It can be in any material.      I know...

It seems like this can is rarely mention on Head-Fi (I searched on the site), how good are they? Also, how much are they worth(used in good condition) and how about used but with worn-out pads? I might be able to get a pair on a price which I don't know if it's a good price point of not. 

Do I need a receipt to RMA my Turbine Coppers despite having lifetime warranty? Yes, they are genuine, so don't ask if they're fake.

What sounds do you guys use to test soundstage? 

I can get a HD 555 for $50 shipped, should I get it? Is it comparable to what I have? AD300, JVC RX900, and Koss Pro DJ 100.

I've always been into the low to mid-fi part of headphones and IEM. I've have and currently own the AD300, Koss Pro DJ 100, KSC75, and RX900. I plan to sell most of my headphones and maybe IEMs to create a ~$200 budget for a higher end headphone. I listen to all kinds of music(mainly electronic...

I just saw this under their weekly special for $10. One thing caught my eye is that the diaphragm is titanium coated....KSC75 drivers?    The specs are nearly the same other than the KSC75 has a sensitivity of 101dB/1mW and the 35SPECIAL's 103dB/1mW.   Anyone know if they uses the same...

Alright, I scored a $95 Triple Fi on Amazon a while ago and after using it for 3 weeks I RMAed it due to crappy cable. Today, I received it back from RMA and when I plugged it in to my sound card...it sound like crap.    When I first got it (from Amazon), it sounded like there's no upper...

Is there a difference in sound quality between the HMD-25 and the regular HD-25-1 II(and other varieties, BS, BA, C, etc.)?   I know the HD-25 is 70 ohms and the HMD-25 is 600 ohms, but how about sound quality?
