The Sennheiser PX200 II is already doing its work very impressively. It sounds better than my standard HD428, it really is good.

AGREED!  I just picked up a pair of the PX200 II... and LOVE THEM!  Sound like 'Baby Grados' to me.

Watch out with your volume, I am prone to crank the volume high from my DAP.

Yea, they definitely go loud.  I'm using them from my Fiio E5, which has a LOD plugged in from my 80GB iPod Video.

Folks!

I just bought second hand (for 25 euros) a pair of Sennheiser HD428. Well... they sound horrible to me (much, much, too much bass!), so far from the analitical sound that I like so much.

 

I was so close to through them away but I decided to give them a second chance!

 

With the help of this article, I have dismounted the headphone and stick one 10 microF capacitor in serie with each speakers (for filtering the low frequencies).

 

The result is brilliant! - not so far from the sound of my AKG K240 monitor!

 

So... why not giving them a second chance!

Adding to my previous post : a capacitor of 22 microF is better. It makes the -3db cut off frequency to about 200Hz.

Too much base on the 428s? Bah. I thought the bass sounded good; until I turned up the volume and I heard distortion. It made me want to cry. I haven't touched them in around 2 weeks... maybe I should give them another try.

I know this is an old comment, but try the re-cable.  It Will help with the sloppy bass at the extreme.  You may also want to add a Fiio E5 to make sure the headphone is getting enough juice.
