JDS OBJECTIVE 2. Headphones amplifier.


AMPLIFIER DESCRIPTION

The Objective2 is an open source headphone amplifier designed by NwAvGuy, with emphasis on benchmark performance and low cost. This item includes a fully assembled and hand tested O2 headphone amplifier, ready for use. You will only need an AC adapter suitable for your region.
The O2 has created a stir in Head-Fi.org’s do-it-yourself community.

El trato por parte de Headphoniaks, excelente. Lo pides y te llega al dia siguiente, perfectamente embalado y con regalo sorpresa!.

Lo dicho, un verdadero lujo.
