I would go with Pass as tubes just aren't the same animal when asked for gobs of current. You might want to check out Magtech amps to see if he has an integrated in the works. That is Sanders Sound Systems. The guy has been working on amps specifically for planars for years and now has this amp for magneplanars. For the sake of arguement I will say ARC is the most SS sounding tube gear I have ever heard.
