Unit is good, but compromised. User manual is awful. One of the worst I’ve ever seen. Almost insulting. The power cable is a cheapo wall wart?! You’ve got to be kidding. I spend $1700 for an audiophile head amp and get these two extreme compromises? Four stars instead of five for these issues. *And you force me to submit photos to get the unit registered? Give me a break! You need to rethink some of your ways of doing business. This is the audiophile world, not mid-fi.
