hd6x0 really need a good desktop amp to reach their full potential. Even a cheap desktop amp will do the job fairly well. unfortunately, pa2v2 just doesn't cut it. And remember that the k701 is a known to be super hard to drive, no way in hell a pa2v2 well be able to bring it to its full...

Anyone in Canada know a place to get HD650's cheap? Every canadian site I've looked at has the hd650s listed for $500-$700 + I don't think J&R ships to canada any help is appreciated

  Anyone else notice Eminem rockin the d5000/d7000 in this brisk ad during the super bowl? Looks like Eminem has good taste Keeping pressing 5 during the vid to get a better look at em

I don't know too much about the p3+, but it is also rollable, and it comes with a crazy amount of opamps/buffers. http://www.head-fi.org/forum/thread/371427/ibasso-p3-opamp-rolling-thread-let-the-rolling-begin   but remember its discontinued now, so you would be looking at the for sale...

hd555 is not recommended for library use. I still recommend a closed pair for situations like that. You won't find that from sennheiser. Look elsewhere

im gonna miss that weird ironstone/marble finish...

Quote: there aren't really many popular models other than the m50s. The Ad2000 deserve some respect, although i haven't heard them, from what i've read they can compete with the big boys

the k1000s and the stigmas, or any other similar electrostat makes you look like you have dumbo ears.

those look identical to mine... although mine are the older blue box version which have a tad more bass, while the white box version (the one you have) is more neutral and balanced. It could just be that the m50 isn't the right headphone for you, as everyone has different ears.

Quote: yes it comes with all the necessary parts. the only thing you supply are the two 9volt batteries, the altoids tin, and the interconnect cable

did you make sure the you inserted the opamp the right way? the side of the opamp with pin 1 (denoted with a dot) goes on the notch side of the ic socket. You could have shorted the opamp by inserting it the wrong way. 

Quote:   I've built this cmoy before. It was my first diy amp build. Very very very simple. It comes in a kit as well so you won't have to hunt for parts. The layout is a lot more simple than the tangent one because there are no unnecessary jumper wires.  ...

Forgot to mention the P4 is rollable, so you can adjust the sound to your tastes
