Wired and Wireless

The CEntrance BlueDAC is a rather versatile device, and a worthy partner with some of the better high-end headphones on the market. If you have a decent wired headphone, BlueDAC will likely make it sound better than you've heard it sound before.

I received my BlueDAC today! It is an awesome little device; I love it...

I still have the same cans on a few hours later and I don’t want to take them off! The BlueDAC is in my pocket and I’m roaming around the house with it connected to my laptop via Bluetooth. Thanks!

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!

As an audiophile listening device for all types of heapdhones - even power-hungry and balanced models -BlueDAC dots all the i's—use it as a wired or a wireless DAC/Amp and enjoy high quality sound either way. And weighing in at only 120 grams, it's extremely travel-friendly. Trusted review sites, including CNET and DAR love BlueDAC for its excepional sound quality and portability.

Bad Guy Good Audio Unboxes and Reviews BlueDAC








Bit-4-Bit Digital Audio


With over 100 licensing clients under our belt (Benchmark, McIntosh, Lavry, others), CEntrance wrote the book on USB audio. We designed DACportable as a true 32-bit device, ensuring"bit-for-bit" audio fidelity, at all supported sample rates, across all supported OSs.


Precision Clock Oscillator


The art of digital-to-audio conversion is in the quality of the clock. CEntrance's clock management system uses military spec clock oscillators with 10ppm precision. Our JitterGuard™ clock cleanup system earned us enthusaistic reviews from Stereophile and dozens of other audio publications.


Class A Headphone Amp


Capacitors introduce distortion. DACport's Class-A audio circuit is direct-coupled (capacitor-free), maintaining audiophile quality all the way to the headphones.


18V internal power


DACport's advanced, low-distortion Class-A amplifier circuit runs on super-clean 18V rails (±9V, bipolar supply). Higher voltage means lower distortion, higher headroom and more output power to drive any headphones.


RoHS Compliant


Our products are sold all over the world and we go to great lengths to ensure compliance with international regulations. DACportable is RoHS, FCC and CE-compliant, which ensures safety and protects our environment.


Made in America


DACportable is designed and assembled by CEntrance in USA from components sourced from around the world. When you purchase our products you are bringing manufacturing jobs back to America. Thank you for your support!
