I have this idea sitting in the back of my head for a long time, and didn't follow up mainly due to the lack of time as I'm preoccupied with other projects (some of which are related to stereo/headphones as well).
Eventually I've decided to share it with this forum and see what other member of the forum think about it, so that if there's some interest I will follow up on that - be it alone or with some other member of the forum.
The K340's are probably amongst the most heavily modded headphones ever. I've had lots of these, practically all of which I've modded with any possible mod, or at least so I thought :)
I was thinking, the AKG K340's have a small PCB with a cross-over which consists of a first order filter (resistor + a small transformer). Well, in speakers design there's a very large following of active cross-over, so why not do the same with the K340's?! :) Some would sat the inclusion of the transformer is just another reason to do this, since the transformer can increase distortion.
I was wondering if someone else did this already?
It shouldn't be hard to do, there's only the question of whether there's the will to do it. From all of the K340's I've had in the past/some I've modded for others, I have a few spare parts. So I can easily draw a schematic of the PCB version I have, as well as part value (including the voltage gain of the transformer). Obviously I will post anything I'll find out, but first I'd like to know what others think about it/if there's interest this.
