iFi Audio Pro iDSD Signature (DAC, Amp, and Streamer)
The iFi Pro iDSD Signature is a powerful DAC, preamplifier, network music player, and headphone amplifier rolled into one compact package. It's a state-of-the-art device that can handle all of your digital music sources, from high-res downloads to lossy MP3s and everything in between. It packs four Burr-Brown chips to reveal details in your music you've never noticed before, giving you a truly high-end listening experience.
The Signature model has an upgraded polished aluminum remote with expanded control, including filter switching and upgraded galvanically isolated internal componentry to reduce overall system noise. It also has a tube stage with a precisely matched pair of new-old-stock (NOS) GE5670s to give your music a unique warmth and character. The iPower Elite outboard power supply is also included, with its aircraft-grade aluminum chassis and ultra-quiet, clean power.
The Pro iDSD also offers three distinct output stages for you to choose from solid-state, tube, and tube+. The solid state uses a fully discrete Class A topology for assertive but balanced output over an extremely quiet noise floor. The tube and tube+ modes both use the GE5670 tubes to drive the stage and reduce negative feedback to emphasize the tubes' musical harmonics. You can choose from five digital filter settings for PCM-based signals, and use the DSD modes not only for DSD content, but also for PCM-based files.
The Pro iDSD also has flexible connections to accommodate practically all types of digital audio sources, along with standard 1/4" and 3.5mm outputs, as well as a 4.4mm balanced output. And the free WiiM Home app for Apple® or Android™ devices integrates all your music choices into one simple interface.
In conclusion, the iFi Pro iDSD Signature is a great-sounding device that will let you hear detail and dimensionality from your favorite digital music sources. It's an all-in-one DAC, preamplifier, network music player, and headphone amplifier that will bring your music to life. If you're looking for a high-end audio solution, you should definitely give the Pro iDSD Signature a try.
