For audiophiles and music lover who are interested in record production and engineering.  This is the place.  It features hundreds of HD video interviews from well accomplished record producers and engineers including Trevor Horn and Mike Oldfield. (November 2012)


Sophia Electric

A small manufacture of excellent tube amplifiers. Owned and operated by husband and wife team, Richard and Sue Wugang with their showroom/office in Vienna Virginia USA. I have experience of owning their amplifier and it was excellent in terms of performance and value. Although both Richard and Sue are originally from China, they design, engineer and assemble all of their amplifiers in the USA. Richard once told me that this was the only way that he can ensure every details of the amplifier can be made to his specifications as he takes great care in tweaking the design to his full satisfaction including the placement of components and how wires are being routed. They are not only responsive but extremely nice people to deal with. I have met both of them personally. Sophia Electric also offers tubes and parts that are manufactured to their specifications in China, graded and selected by Sophia. BTW, my dream amplifier is Sophia’s 845 amp. It is expensive at $20,000 a pair but at least as good if not better than the 845 or 211 amps that are priced several times more. (November 2012)
