HERUS+ is our smallest form-factor, audiophile quality USB to Headphone DAC. It uses the USB Audio 2.0 Asynchronous protocol and supports DSD64 and DSD128 as well as high data rate PCM at 24bits up to 352.8Ks/S.

It is a USB powered device that achieves more than 100dB of SNR, (typically 108dB) and is capable of driving 2.4V RMS, (ie 6.8V pk-to-pk) into headphones from 600 Ohms to 32 Ohms. The distortion in all cases is better than 0.005% (85dB): the measured THD+N is typically 89dB for 32 Ohms and 90dB (about 0.003%) for 600 Ohms. HERUS+ has a low power mode and the ability to select advanced up-sampling filters.

Warranty
1 year parts and labour. (Detailed Warranty information may be found under the “HERUS” menu item on every page).

​HERUS+ will enumerate to the controlling computer and register itself as being able to handle volume control internally. BlueIPhoneAlmost all music player applications will then send control commands to the HERUS+ which it will use within the ES9010-2M DAC chip to implement high performance 32 bit volume control processing. This is significantly better than the volume control implemented in the music player software. HERUS+ is easy to use: plug HERUS+ into a USB 2.0 (ie High Speed port) [with USB+ Audio 2.0 enabled if on MS Windows] and select HERUS+ as the output device in your system control panel. That is all there is to it… IMPORTANT: Please note: some (if not all) software on the PC, MAC and Linux will, the first time HERUS+ is connected, set the volume to 0dB. That is, to the highest volume level. This may be very loud in the headphones. On subsequent connections the music player application will recall the last volume setting, but we have seen instances where plugging into a different USB port again sets the volume back to 0dB. Consequently, we strongly recommend that you plug the HERUS+ into any new port on your computer with the headphones unplugged, and set the volume to a reasonable level prior to plugging the headphones into HERUS. Additional note:  The volume level may rest to full volume if the headphones are swapped out while music is playing – please pause the music while you swap headphones when using HERUS+. For more details see this FAQ note. You may, if you wish, use HERUS+ as other than a headphone driving DAC. For example, when driving a power amplifier you will find that HERUS+ is a capable and high performance system component. It is perhaps the optimum and lowest cost solution to accessing DSD music from your computer collection. Please read our FAQ on this question for more information.
