SA-T7 Diamond


Stereo Tube Preamplifier

With the SA-T7 Diamond we have created a very special edition of our reference preamplifier, the SA-T7 MK. The heart of the preamplifier was equipped with original Telefunken tubes from German production. The result is a special edition in a class of its own. Everything the SA-T7 and SA-T7MK were praised for is made even better with the use of these tubes.
