The Teac UD 507 is a DAC/Preamp/Headphone amplifier has been completely redesigned with bits of their higher-end 700 Series implemented.

TEAC UD-507 Headphone Amplifier/Preamplifier/DAC

Introduction

The Teac UD 507 was sent to me a few months back and I figured that this would be a quick review. I mean how involved could a preamplifier headphone amplifier be?

Quite involved actually.

It is quite simply one of the coolest pieces of audio gear that I’ve gotten my paws on. It’s also one of the most feature-rich and I’m still coming to grips with all that it has to offer. I feel like I’ve just scratched the surface.
