Nice. I believe I am the sole GS1000 proponent on HC. I think they are excellent but flawed, but having said that I believe almost every headphone is flawed in some way. They excel at very flat, neutral recordings, like soundboards, or old unfutzed with soundboard sourced tapes, or mic-on-stage soundboard patches. Despite the recessed midrange, vocals and guitar plucks come across as very lifelike and natural. I also love the way they present live drums. Classical typically sounds good with them. I particularly like them with solo piano. Some say they do well with jazz, but I still prefer the rs-1 with jazz since so many horns are to bright on the gs1k.
What the gs1k does for me is compliment the rs-1 well.
