iFi Audio - Pro iDSD 4.4 Signature - DAC + Headphone Amplifier/Preamp
Standalone. Streamer. DAC/amp. All with the X-factor. The new Pro iDSD Signature has been upgraded to the next level.
Enhancements to Signature Edition:
• Sonically-darker background and more punchy bass
• Upgraded power-supply components to lower overall system noise 300%
• Revised circuit design incorporates even more ultra-grade audiophile components
• Precisely matched, hand-selected NOS GE5670s tubes
• Added support for USB1.0 (PS4/PS5)
• New Aluminum remote control
• Top-of- the-range iPower Elite power supply include
The Pro iDSD Signature builds on the strengths of our multi-award-winning DAC/preamp, network streamer, and headphone amplifier, featuring even more ultra-grade audiophile components.
The Pro iDSD Signature is a ’state of the art’ reference digital to analog converter. lt is able to excel in many scenarios - as a wireless hi-res network player or the central DAC in an expensive high-end home system, to quote just two examples. The onboard balanced headphone section means high-end headphones can also be directly connected to it.
