Vertere Acoustics PHONO-1 MK11 L Phono Preamplifier
VERTERE ACOUSTICS PHONO-1 MK11 L PHONO PREAMPLIFIER ANNOUNCED
Touraj Moghaddam, founder and chief executive of London-based British HiFi brand Vertere, has announced that the PHONO-1 MKII Phono Preamplifier has been improved.
The new Vertere Acoustics PHONO-1 MKII L features improved performance, a new gold-plated L-shaped Printed Circuit Board and enhanced accessibility for the customisation DIP switches.

Touraj says that the sound quality improvements are ‘subtle but significant’. The MKII already was better than the original due to the more optimal choice of components. Vertere says that the L takes this further with non-trivial PCB layout improvements. Moving the linear power supply to the main PCB allowed a significant track and ground plane layout optimisation. The new design ensures signal tracks are of equal length, impedances lowered, and track widths adjusted to direct current flow.
GROUNDING
The PHONO-1 already included an unusual grounding selection switch with three positions giving a choice of Hard Ground, Ground Lift, or Soft Ground. This, claim Vertere, in certain installations, may achieve even lower background noise from the record player.
MOVING MAGNET & MOVING COIL
The Vertere PHONO-1 MKII L is user-configurable for most Moving Magnet and Moving Coil Cartridges available. The DIP switches on the bottom of the unit facilitate the choice of 15 input impedances and 9 options of capacitance together with 10 choices of gain.
POWER AND PHONO CIRCUIT BOARDS
New ‘L’ shaped high-quality gold-plated PCBs for the main phono circuit and the mains power transformer are designed to ensure optimised grounding and power distribution. In addition, stainless steel shield ensures that any unwanted interference is kept well away from the audio signal.
HIGH END FINISHES
The PHONO-1 is available in a range of high-end finishes, including a new DG-1 design featuring a front panel to match the new Vertere record player. Other finishes are available: Silver aluminium, Signature Vertere Orange and Semi-matt Black. L The power LED is now orange to easily identify the MKII L version.
