NextDrive Spectra Portable USB DAC – The World’s Smallest 32-bit DAC Headphone Amp for Truly Mastering Your Sound On-The-Go (Spectra USB Type-A)

Product Description
Welcome to the next milestone in the audio revolution: The Spectra from NextDrive. Play high resolution audio files up to 32-bit PCM or quad-rate DSD directly to your headphones or speakers, bypassing your device’s stock audio hardware. The Spectra packs plenty of power with enough output to drive all but the most demanding headphones, and its ESS Sabre 9018Q2C chip delivers sound quality previously assumed to be impossible in a form factor this size.

The revolution starts now.
Audiophile reviewers around the web agree, the NextDrive Spectra simply cannot be beat in terms of price versus audio quality, tech specs, portability, construction quality, ease of use and overall wow factor. Thanks to its ESS Sabre 9018Q2C chip, the Spectra delivers exceptional bass speed and clarity, well-balanced mids slightly forward, smooth treble without a trace of harshness.

iPhone and other iOS devices, as well as devices with USB C connectors, are not compatible with the Micro USB version; users of these devices should purchase the regular USB A version of the Spectra. A separate adapter will also be required, sold separately.
