Struss R150 Amplifier

The Struss R150 offers an extremely dynamic and detailed sound, while still natural and without the distortions associated with transistor devices The sound of the amplifier together with a well-matched system is full, complete and beautiful. The entire acoustic channel was realized using the JFET and HEXFET technology, which allowed elimination of bipolar transistors and the associated distortions.

The classic look of the Struss R150 contains many elements in common with the highest model of the Struss amplifiers, the R500 (colours, knobs, etc.), ensuring the consistency of the Struss Amplifiers Company products.

The top quality built in headphone amplifier constitutes a high value added for our customers. This headphone amplifier utilises an independent channel (Class A) with a separate power supply, JFET technology and a complementary output.

The Struss R150 amplifier is produced industrially in a factory with numerous quality control certificates. This means high standards as well as full manufacture repeatability.

As the Struss Amplifiers team we are fully convinced that this amplifier will constitute a great attraction for our customers in its price range.
