Try to get it with massdrop I got mine at $307 and I am considering buying burson audio supreme sound opamp probably that can help sound quality any of you guys got any experience with that opamp?? Other item you could consider is the teac ud501

I recently bought the fostex hpa4 because I considered the fostex th600 but I'm leaning into the audeze lcd 2.2 Any impressions on this pairing?
