Currently we are working on a switch box to compare a pair of stereo speakers and a pair of amplifiers at the same time. The levels between the speakers and theamplifiers can be adjusted to ensure the same conditions for the speakers and the amplifiers. It is even possible to compare a pair of sensitive valve amplifiers! this makes the switch box a unique tool to compare between speakers and amplifiers in a just environment. Scientific blind tests can be made easily and reproducable.

Stay tuned!
