I will do a double check on the fuse size and get back to you this evening. Fred also told me he wasn't real crazy about Synergistic Research fuses in the Lampi gear but after talking to the folks at the Cable Company I decided to try the BLUE. They told me it was something much better than anything SR had produced before. So far I really like it. I think a lot of this will be system dependent. I am using an integrated tube amp to mate with the Amber II and I didn't want to get too soupy sounding. I wanted a mix of the beautiful tube magic but yet with the detail, solid lower end, presence and great vocals. As of today I feel like I am getting these attributes.
Depending on your system I would consider the Audio Magic Beeswax fuse.
