Better Audio, Built for Travel

The sequel to hiliDAC’s well-received Beam, the Beam 2 is a high-performing DAC/amp that easily fits in your palm. To deliver exceptional sound and amplification that punches way above its weight class, the Beam 2 is equipped with an audiophile-grade ESS9281C Pro DAC and an amplifier capable of outputting 240 mW at 32 ohms. It also features a 3.5-millimeter single-ended headphone port and 2.5-millimeter fully balanced port. The Beam 2’s left and right channels have independent op amps and high-thrust circuit designs, and the light on its body changes color according to the decoded music format: red for SD audio, blue for HD audio, and rose red for MQA audio.

Note: At checkout, choose black, red, blue, yellow, or gray.

Got it directly from the producer (Audirect). So far I am not impressed. It sounds good and seems suitable for not too sensitive mid impedance iems and low to mid impedance full size headphones. However, for headphones like Sennheiser HD600/650/800 or ZMF Atticus/Eikon with higher to high impedances there is not much headroom on the iPhone 6s Plus and the 11 Pro Max. With 100% volume said phones are listenable but don't really get enough power. And this is in balanced mode where the output is higher. OTOH very sensitive iems like CA Andromeda have hearable hiss as soon as the source provides a signal. When the source signal is switched off or set to pause the noise floor on the Andro goes away in Spotify after 3 s or so, in Tidal after 6 to 7 s. Moreover, there are pretty loud crackling noises on the Andromeda when switching a song in Spotify on the iPhone (funny enough not everytime but regularly). This makes such sensitive inears near unusable. Even with high impepance full size headphones pretty loud cracks occur sometimes when switching songs in Spotify on the iPhone. With Samsung S10 5G there is more power than on the iPhone. This way the Beam 2 can drive an Atticus to more than loud enough levels in balanced mode. And the crackling noise when switching songs seems to be a bit weaker, even with the Andromeda. Edit: After applying the new firmware (0125) the noise when switching songs seems to have been reduced to mostly unproblematic levels. The noise floor problem however is still present. And there is noise even when there is no source signal at all, stemming from the GSM functionality. Only the flight mode brings it down to near zero.
