I put the L cushions back on last night and listen to a few songs. Then I put the G cushions back on to do a comparison.
1) Bob Dylan - Mr. Tambourine Man
2) Cowboy Junkies - Sweet Jane
3) New Order - Age of Consent
I have to say that for me I prefer the sound of the L cushions to the G cushions. The bass is deeper and tighter. Also, for me the vocals seem closer to me and less distant. Lastly, I feel like the highs were better tamed. The G cups are much more comfortable however. For me it's very much dependent on the type of music and amp used, that seems to determine which cup sounds better. I'm was convinced that the G cups sounded better a few months ago but now I'm not too sure. Both sound great....such difficult decisions we Grado fans face
