A good friend who is a very competent EE, has built a range of Amp's in both SS and Valve, of which Valve is their most preferred.
Recently they have bought into a DHT Pre Amp design and have been trying it out on owned Amp's.
The Valve Pre' coupled to a SS Power has proven to be extremely impressive and one they want to demo' to the Local HiFi Group at a meeting.
Demo's ser aside for the HiFi Group as a result of a experience had, usually prove to be very very well received by those receiving the demo' and new experience.
