Yes, the Spore4 is heavy and rigid. I think the Silver Complement4 is a very good alternative. As an owner of an HE-1000 and former owner of an LCD-4, you might find that you prefer how these headphones sound connected direct to DAVE rather than connected to your GSX-Mk2 or Moon 430HA. This would not be a bad problem to have since it would mean more money back in your pocket and a much simpler setup but the point is, before you spend a lot of money on Spore4 interconnects, you might want to see how you like the DAVE's integrated headphone amp first.
