There's a glowing review on Positive Feedback. Comparing favorably with NAT Plasma and Einstein "The Tube" MkII preamplifier. But I couldn't find any other review/feedback online. Anyone heard this preamp? I'd like to hear your opinions. I heard it's balanced. But there's only a pair of 45 tubes. And although being DHT, it's a very small unit.
