If you are open to the 2nd hand market I would look at the original Meze Empyrean. Beautiful headphones and most people seem to agree they are way more comfortable than Grado. Original price was $3000 but they can be had for well under $2000 these days. Which is similar in price the the GS3000X you mentioned. Meze moved on the Empyrean II so the original is a great value now.
