Also, what are your guys' opinions on the D400, just because there's some pretty good prices on those, and my inner cheapskate is acting up, so I just wanted to know if anyone has tried them and what they though. Idk! I have no clue right now which to snag haha

Man, now I'm getting all turned around haha, who was I kidding though, expecting this to be an easy choice.  I never did consider the D600s though, those are a sexy looking pair of cans though, and they do sound fairly comparable to the d2000s? That may seriously be an option, just as long as...

Thanks for the input it's much appreciated, I've always been more of an IEM person so all the input is really much needed, thank you.  So if we're narrowing it down to 3 headphones (plus a fiio e17 xD ) which should I go with: Beyer DT 770 Denon AHD2000 or Sony MDR-xb1000

Well this is definitely the place for me to be, gotta get that bass, but right now I'm overwhelmed with all of the choices on the table and I've been trying to read all 540 pages, but I was looking for some guidance. So no surprise I'm looking for a headphone with bass, without spending /too/...

Well, I am and I am not, just because I don't believe there is such a thing for android phones, it has to use a USB OTG cable; I was able to use an LOD when I built the Cmoy and had an iPhone. But the LOD was generally what I was looking for, but since I can just use a OTG cable, that brings me...

huh okay, I think I'm starting to understand a bit better here...so I mean, seeing as IEM don't really need much amplification, something like a SkeletonDAC may sound better, just due to the fact that it would avoid the built in amp, and potentially just bring out more of the natural headphone...

Thanks for that Tomb, really helped me understand a little bit better, since it is possible to use my phone for output, can you put on an op-amp from the DAC? like...run through the dac, and then an op-amp or is that just too much stuff going on - or not even possible. Thanks a ton for this info...

Quote: Tomb thanks for the reply, but I did specify the headphone I was primarily going to use, and it wasn't a question about if they need to be amped or not, I'm  building the amp regardless for fun, but I was trying to understand if I needed to do anything special for the input...I think...

Okay well now I did a bit more research and learned more about what I need...But now I guess I have a new question; for a headphone that with a relatively low impedance (16 ohms) and a sensitivity of 97db/mw @ 1kHz be okay with an amp at an impedance of 32 ohms? And if not, is there a way you...

So I was looking into building a new headphone amp, my original just being a CMoy amp; this time I want to do a lot more of the work myself, not just following step by step directions...I probably will fail! but at least I'll have fun doing it! So my question, and I do apologize if this has been...

Well all of those shells are gonna make even more people very happy with their grados. Just received mine cocobolo shells from Billa, and like everyone else, all I can say is wow. I am using a GradoSR60i with the cover removed and 5 holes punched. It sounded much better than the original sound...

Thanks! But unfortunately, due to my lack of any electrical schematic skills, I don't know how to read that :(  

I just completed my first Cmoy pocket amp, and now I want to build the A47 amp for my Grados. The problem is, when I search for the parts list everything is from 2005 and none of the pictures or links work. So does anyone know the list off hand, or know a link that can explain everything I need...

Well I finally figured it out, but now I have another problem, if anyone cares to help. Right now I am getting really low audio in my right hear, and very static-y sound in my left ear - at high volumes. When turned low the left ear starts to "stutter" and the right ear is non-existent...what is...

So I have better building the Cmoy amp using the Tangent tutorial to help me build it. But now I'm stuck. The part that I am stumped at is the correct wiring for the Power Switch, the potentiometer, and the headphone jacks. No where on tangents tutorial does it tell you which prong is the left...
