  • Loudness: no
  • High Filter : no
  • Mute: yes, - 20db
  • Direct/Line-Straight: yes
  • 8 Ohm : 2 x 90 W at 0.004%
  • Robust chassis, so-called Gibraltar construction, reduces the distortions possible due to vibrations.
  • Large-sized, coiled toroidal transformer always has sufficient power available even for the highest dynamic peaks.
  • Preamplifier part: Low-noise NFB equalizer amplifier with high gain.
  • Power amplifier part: Purely complementary push-pull stage.
  • Sound control unit with exclusively passive components to avoid distortions.
  • Power amplifier in the super legato linear system ensures high output power.
  • With simultaneous A & B speaker operation 8 - 16 Ohm , otherwise 4 - 16 Ohm
  • Direct input for unadulterated reproduction of the signal sound source
  • Tuned Up variant of the F570ES
  • The F670 is nothing more as a pimped version of the F570, the screening capacity of both the output stages and the output stage front ends was doubled and smoothing inductances were additionally inserted there. The foil-C in the filter network of the phono preamplifier now have 100V instead of 50V etc.. The audio electronics, as well as the board set is the same. The additionally offered preamp output is a fake and nothing more than a down-energized power amp output, like the headphone output. Whether this is worth the meanwhile quite large price difference of both models in the used market, everyone has to decide for himself.
