I just got the 2nd orange fuse in my amp, sounds good from the start, no idea why. I have one in my preamp that one take awhile to sound good, it sound ok to start but didn't fully settle in after 150 hrs. this one once in the amp, quieter ie. blacker background, wider soundstage, more holographic, voices the most difference it sounds more natural, love this part, all others the timbre just seem to sound more correct or natural, does seem to have a bit of grain sometime, very strange most SR products take long time to break in, the power cord is the worst
