Project Description

Head 2 – Headphone amplifier

The Head 2 is a Class-A Push Pull circuit design . This is the second headphone amplifier in Trafomatic Audio production coming after very sucefull model Experience Head One. 3dB of feedback and 100% tube amplification delivery 2W into 50 Ohms .It’s tubes have been hand-picked based on their long established reputations for sonic virtue.

The ‘overbuilt’ power supply features robust multi-stage high-voltage ltering, for superior low-frequency performance.

A proprietary output stage with II C core output transformers accommodates a wide range of headphone impedance from 25-600 Ohms.

The Head 2 drives many pairs of headphones with no sacrice to delity and with ease. This is the ideal amp for shared listening sessions. The Head 2 also working as great tube preamplier capable to drive all power amplier even with very low input impedance.

The Head 2 features uncompromising quality in build and design throughout.

A timeless design built to last a lifetime and deliver an unmatched sonic.
