The circuit design is based on a classic “Current Source Loaded Grounded Cathode Amplifier (mu-follower), using a pair of ECC82/12AU7 (one per channel) tubes. The circuit has been specifically designed for ultra-wide frequency response, linearity, low distortion and low output impedance. It operates in a Class-A single ended configuration with no feedback.
Key Features
· Vacuum Tube single ended stages
· Low output impedance
· Class A gain stages
· Zero feedback
· Low current design
· Relay-controlled input selector
· Power supply rectification using ultra fast-soft recovery “Stealth” Diodes.

All I can say is that I love that thing, especially for the money. The tubes are barely warm, it doesn't have the classic problems of tubes such as frequency range restrictions or slow bass control, and is in fact very fast and very, very neutral. ( that thing is going way up there in the range, in energy) Still has pure emotional and 3 D qualities, just with a more neutral rather than classic tube signature. I love it, what can I say? And those who know me are aware of the fact that I don't just take on products for the sake of marketing. (hell, look at our digital prototype of nearly 2 years. It's still digital, and doesn't meet my "emotional orgasm" criteria. Of course there are folks who like this digital sound, and it would be so easy to be another manufacturer using $ 30. modules in a $ 900. amplifier, but that is not me.) It has to float my own boat, and it has to be stellar in price / performance, or it's a no-go. After all, I have way too much to loose here with my reputation if it wouldn't.
As for production and sales, all I can say that you guys are completely nuts, my friends. I posted this when ? Less than 12 hours ago ? Already have 9 confirmed orders, sight unseen. Aaaaargh. We're looking at a realistic 6-8 weeks before we can ship in bulk, mostly because of vendor lead times.
Anyway, thanks for your interest,
Klaus
