MQA-Supported Beam 2

Hilidac has created the MQA-Supported Beam 2 which enables you to experience the abundant music details in the artists' recording room.

The Beam 2 is the first true BAL + Non-BAL dual earphone ports USB product to offer an integrated MQA renderer hardware, making MQA playback easy and complete. That means allowing it to connect to an MQA Core signal and complete the final unfold step of an MQA file. The Beam 2 LED glows magenta to indicate the unit is rendering an MQA stream or file, where the final MQA unfold is delivered.


The Beam 2 features DUAL ESS ES9281C PRO and Dual OP-AMP CHIPs, it also comes equipped with two ultra-low Femtosecond phase crystal oscillators designed to provide best-in-class audio performance at 118 dB DNR and 0.0003% THD + N.

Good and warm

It’s a good DAC but when is working the temperature is very high

Jeffrey Kuperman
Not bad for the money

It sounds very good. I like that I can listen to my FLAC, DSD and MQA music with the same device. It gets uncomfortably hot to the touch very quickly. And it requires easy-to-drive headphones to achieve a decent sound level.

Don't trust appearances! This DAC is a mistake...

One of these purchasing mistakes, you, hopefully, are not going to make! It all started with the original USB-C to lightning cable stopping working within days. Linsoul kindly sent a replacement, which lasted for another month or so. Although the listening experience was itself decent to average, plugging and unplugging the Hilidac dongle resulted in a loud, extremely unpleasant popping sound. The auditory discomfort is comparable only to the the sound of nail scratching on a chalkboard. I had to take the earphones off my ears every time before plugging and unplugging the DAC to the iPhone. But then, 50% of the time, the Hilidac Audirect Beam was not recognized by the iOS, so I had to start from the beginning. Once connected, the Hilidac would pick up electromagnetic interferences from random devices around me, making the listening experience disruptive and annoying. When I contacted the company for support, they sent me a Windows-only firmware update link, although I informed them that I'm using their product in a Mac OS environment. The problem was never solved and Audirect just stopped responding. I was left with a badly functioning device and a bitter taste in my mouth. Eventually, I quit trying to fix it and bought a DAC from a different company (not on Linsoul) for 30% less of the Hilidac Beam 2 price. It was a day and night difference !! In conclusion, despite its sleek, minimalistic appearance and boastful specs, the Hilidac Audirect Beam 2 is not ready for prime time and is a complete waste of money. You may wish to look elsewhere!
