Product Information

Pro iDSD Desktop DAC

There’s no wrong way to enjoy your music as long as you’re enjoying it, so we’ve created the Pro iDSD reference grade DAC and amp combo to be the centerpiece for whatever strikes your mood. In this upgraded version of Pro iDSD we have switched out the 2.5mm output for the 4.4mm, added a little more juice with 4,200 mw for balanced outputs and 1,575 mw for single ended, and upgraded the PBC. When convenience matters, stream from your favorite services like Spotify, Tidal, and Qobuz over WiFi for up to 24 bit / 192 kHz high resolution streaming audio. For the ultimate in hi res audio connect your PC, laptop, tablet, digital audio player, Android, or iPhone (with Apple Camera Connection Kit, not included) to the high speed USB 3.0 input for native playback of all formats, including FLAC, WAV, PCM, DSD and even MQA decoding. The micro SD TF card slot and USB A inputs let you connect your external library, and you can run a network usb drive through the built-in ethernet port. Dust off your CD collection and plug in your DVD player via the SPDIF optical toslink jack to rediscover old classics. On the back, RCA jacks and a balanced 3 pin XLR output connection work directly with your home audio amplifier or receiver allowing the Pro iDSD to function as the preamplifier for your home audio. When speaker listening isn’t an option, the built-in headphone amplifier will drive your favorite pair of headphones with ease as you listen to your favorite beats.
