I've been gaming with the HD 555s for a little over 3 years now. I just recently purchased a Ear Force DSS 5.1 Dolby Headphone Processor. I guess I'm just wondering if it's time for an upgrade? If I purchased the AD700s or the HD 598s, will I notice a difference? Am I fine with what I have?
P.S. I've read over Shin CZ's thread where he breaks down many headphones he's used with Dolby Headphone Processors. He ranks the AD700s and the HD 598s at the top of his list. He doesn't mention the HD 555s which is why I'm posting this question.
