First things first - I have no direct affiliation with this product or the vendor but I'm friendly with the designer. If that makes me biased, so be it, I guess I'm biased.
Now, onto the amp. Basically it's a single ended amp with transformer coupled inputs and outputs to provide balanced operation and was designed to drive anything from IEMs to the K1000 (via selectable outputs). The tube compliment consists of a 7N7 input tube and two 307A output tubes. More details are available on
Todd's site.
I'm certainly looking forward to giving it a listen at CanJam even though it far exceeds the ability of my wallet.
