It seems like over the last few years, we’ve had a lot of DACS and headphone amps to listen to. Some are portable, running on batteries; some are desktop devices with AC connections.

Questyle SIGMA DAC and Headphone Amp

The Basics:

Questyle has produced a striking new DAC and headphone amp combination, which I would call near breathtaking in appearance. It can drive just about any headphone or be a source for a desktop or laptop PC, and it can drive high-quality powered speakers. It also has Bluetooth to keep your headphones usable without wires.

The Rundown:

I’ve listened to a few devices from Questyle, and always found them innovative and good-sounding. The SIGMA takes a few steps forward, with stunning looks, the ability to play almost any digital source, and with around 10-12-hour battery life, it’s going to be great on a trip.
