our new headphone amp KV "Beta" Test KV Beta - EAR IN 3/2017

The KV β is available now - please ask your Silent WIRE dealer for information!

KV Beta
The KV β - the second model of our new high-end headphone amplifier series - is also 100% Handmade in Germany.

The KV β offers the same, completely linear design with high-end components and a galvanically isolated power supply in a separate housing, as our top model KV α. The prime differences from KV α are a different inner cabling (AC 32 mk2 / NF 16 mk2) and a front panel made of brushed stainless steel.

Like our power conditioners, our headphone amps are fully customizable on customer request (at extra cost). This applies both to the housing design (for example, the housings can be painted in all RAL colors) as well as to the internal cabling. Just ask your dealer for an offer for a device adapted to your needs. *

Our KV β also offers a fantastic and classy sound experience.
