SW1X Audio Design™ AMP V "Jupiter" Phono Integrated Amplifier

SW1X Audio Design™ AMP V “Jupiter”

Performance Level 3/4/5
300B DHT Integrated Amplifier


AMP V is a 3 gain stage Power Amplifier coupled with a High Quality Pre-amplifier using our in house designed and in house made stepped attenuator volume control.

Just like the AMP V Titan it is extremely musical and powerful sounding Integrated Amplifier. Larger chassis makes it possible to integrate our famous LPU I Phono stage or the DAC I in one chassis.

The Directly Heated 300B Triodes at the output stage are driven by the popular 6J5 & 6SN7 driver tubes to produce musical and balanced sound.

Available in different versions: Special and the limited Signature version with different power output transformer options (Permalloy or SHiB and UHiB) and all Copper or Copper/Silver  windings
