Here’s the link to the GL2000 mod: GL2000 grill mod/tuning fix by Pokrog. I left the outer mesh in to keep out debris.
Comparing those two is hard because they are quite dissimilar. I have a bit of a bias against the GL2k mostly because I feel like they were oversold/underperform (for their price). They do have a massive soundstage.
The modified GL2K are more similar to the T60rp stock, which I found too bright and bass light. I have used them quite a bit lately and am finding them more to my liking than when I first modded them, but if you gave me the choice of only owning one of the two, its an absolute no-brainer to pick the Argons.
I know sound quality/reproduction is the primary concern but the comfort difference between the two biases me as well. I’m a big guy (6’4") with a big head and the GL2k feels massive to me. I had to add Dekoni nuggets to the headband and there isn’t enough clamp to keep the GL2k from shifting around on my head with moderate movement. The Argons on the other hand, feel like resting my head on the most comfortable pillow. I often sigh when i put them on ( i love the feel of the suede pads). lol
@ShaneD : Did you get yours?
