audio gd precision 2. this thing has more power everywhere than the much hyped ragnarok and weigh much more and cost about a 1000 bucks. it cranks 16w into 50 ohms in high mode socket. I will be ordering one this week. to replace my ef-6. I want to get back to having loudspeakers but I still want to enjoy my beloved he-6. 100w x2 into 8ohms of quality power is plenty enough for my place.
the innards of that thing are incredible. a thing of beauty. just by looking at it, you know it can give the he-6 everything it needs. just massive.
