SW1X PRE II
SW1X PRE II
The PRE II is a pure class A, Output Transfomerless (OTL) line pre-amplifier with Power Valve Output Stage.
Output Transfomerless (OTL) s výstupním stupněm Power Valve. Employing 6V6 power tubes at the output makes the PRE II a smaller brother to the SW1X PRE IV pre-amplifier. It is great enhancement to any tube power amplifier and ideal partner to our DAC I, II and III STD/SPX and LPU I & II Phono products, reducing their output impedance further and enhancing their sound with fullness and authority. With a help of of a PRE II, any source becomes unleashed to drive subsequent power amplifiers to its full potential. More
