BlueDAC – Wired and Wireless Hi-Fi

BlueDAC is the result of our meticulous, painstaking quest to evolve the portable headphone amplifier for the modern HiFi enthusiast. BlueDAC was created with utmost care and attention to detail, down to the last design element, such as the selection of components for best audio reproduction, design for lowest noise and distortion, ergonomic location of controls, and lightweight wearability, all with the goal to deliver the ultimate portable digital audio experience that rivals an expensive stereo in sound quality, but not in size.

It took years of dedicated crafstmanship to bring you this level of aesthetic refinement. Here is the short timeline as a glimpse into the history of our continous improvement.

2009: CEntrance redefined portable Hi-Fi with a revolutionary product called DACport, a small, USB-powered DAC/AMP. DACport's amazing sound quality earned it a place on the presitigous Stereophile recommended components list!

2014: CEntrance added HD file support, offering DSD playback, picosecond clocks and sampling rates up to 384kHz. The ultra-slim DACport HD immediately became a hit and sold thousands of units within months of introduction.

2016: Our upgraded headphone amplifier called AmpExtreme™ offers even lower noise and distortion. But we didn't stop there. We added a Li-Ion rechargeable battery and MFi connectivity. The resulting ultra-portable DACportable got rave press reviews and became wildely popular.

2018: It's hard to build upon the legacy, but we were determined to push the envelope even further. On customers' request, we've added an audiophile Bluetooth input, and a balanced output, offering freedom from cables and total sonic flexibility. BlueDAC is our best portable HiFi amplifier yet!
