  • What is high-resolution audio?

High-resolution audio tells the full story of your songs, by retaining the rich texture and nuances of artists’ original recordings that formats like MP3 throw away during compression. Spectra produces the full range of sounds from original master recordings that are even superior to CD format — all the way up to 32-Bit/384kHz. 

  • Where can I find high-resolution music?

We recommend these great companies to help you get started: HDTracks, Primephonic, Chandos, e-onkyo music, mora,, Ototoy, and Victor Studio HD-Music.

  • What audio programs can I try that support high-res audio?

For Windows and macOS, you can try the following: Amarra, Audirvava, BitPerfect, Pure Music, JRiver, Roon, and Tidal. 

For iOS and Android, you can try the following: iAudiogate, Poweramp, and Tidal.

  • What is a DAC?

Digital audio files make it much easier to carry your music around, instead of using CDs. But to turn these digital audio files into something you can hear, a digital-to-analog convertor is needed to turn the 0’s and 1’s into an analog wave that you speakers and headphones can produce. But not all DACs are alike. Spectra is a dedicated DAC, producing studio-grade quality conversion. 

  • How do I set the volume level?

The volume is controlled by the master volume of your device, so you don’t have to worry about any dials or gain controls. So if you want to turn the volume up, you can simply turn the volume up on your smartphone, tablet, or computer.

  • Does it need to be charged?

Spectra was designed to be compact and hassle-free, so it includes the latest energy-efficient DAC chip to reduce power consumption. That means there is no battery that you need to worry about charging every time you step outdoors.

  • Does it get hot like other amplifiers?

Because of Spectra’s energy efficiency, you’ll hardly notice any heat being generated during use, unlike some other portable DACs.
