TUBE PREAMP II – MK2 highlights
Audiophile reference preamplifier with a so called “tube hybrid” concept and 4 military tubes (2 tubes per channel)
Fully balanced circuit design from input to output
Advantages of this “tube hybrid” technology:
- very high impedance
- very high bandwidth
- very low distortion factors and a “good-natured” distortion spectrum
- “analog” and very precise sound performance
- 4 separated amplification paths, which are not influencing each other
Easy change of tubes without any adjustments just “plug and play”
