Siemens 5 watts power amp together with my Marantz 7. The Siemen amplifiers are very well built, with solid chassis and very neat internal circuit and wiring. However, there is a need for some by-passing of the pre amplifiers in order for it to sound good.My friend David, therefore, went to consult his DIY friend in Germany. Within days, a set of simple instruction was sent. After performing a" by pass" operation (sound like real life operation), the sound from the 5 watts Siemens are exceptionally good! What a change!
For a mere 5 watts power amplifier, see how big the output transformer is! This big output transformer may be the secret as to why the sound of Siemens amp is so good....even with the difficult to drive, low sensitivity LS3/5a speakers!
The Siemens amplifiers with its low watts output is able to work very well with high siensitive speakers such as the Tannoy. the clearity of music and the ability to reproduce real life music really differentiates these amplifiers from the other low powered amplifiers!
