My current setup is:
Beyerdynamic Custom One Pros
I was looking to upgrade my headphones to the Beyerdynamic T90s. From the reviews they seem to offer the extended refinement without sounding too lean in the bass department. The sale price unfortunately is gone. It was suggested I'd need something more powerful than the E17 to power the T90s. I can afford the full retail of the headphones and a new amp. I am wondering if upgrading my amp may breath more life into my COPs until I can save up for the T90s?
Thoughts? Suggestions? Opinions?
