Lead time to build and despatch new orders: 2-3 working days
The headphone amplifier section has been designed from the ground up to offer some of the best, if not the best, specifications and hi-fi functionality on the market today. This has been accomplished by months of development using top of the range audio testing equipment to fine tune and carefully select the most optimum design, layout and components. The specifications achieved speak for themselves. It is powered by the included AC adapter suitable for your region.
The DAC module is designed according to the same principles as the award EHP-O2 portable headphone amplifier and sports equally stunning performance.
This high end DAC is based on the TE7022L UAC1 engine and ES9023 24 bit DAC chip. It supports 16 bit and 24 bit at sample rates of 44.1kHz, 48kHz and 96kHz. The on-board filtered power supply ensures that noise is practically non-existent. The DAC is not clocked by the USB port/computer, instead using a high quality on board crystal controlled oscillator which further improves overall performance. The input signal and power is supplied via the USB input on the rear of the unit.

Noble Hi-Fi Review
“I am not going to do the usual comparisons here because I can sum it up much more easily, it beats everything else that I have tested here hands down.”
