I was thinking that sometime in the future I will upgrade my audio setup and purchase the Sennheiser HD800 headphones, but I don't know what amplifier would be a good choice. Someone recommended the Teac HA-501, but I'm also starting with elecronic music production and I've been told that there would be something better to suit my needs. The two things that I really care about are low-latency and absolute top-notch sound quality. With that in mind, I will happily accept ideas in any price range. The help is greatly appreciated.
