Hifi Man Dock 1 is a station adapted to the HM-901S model as well as the HM-901 or HM-802, which all use the analogue to digital conversion portion of these devices with a sedentary DAC. They can be connected to a computer via USB B input or to sources delivering S/PDIF optic and coaxial signals.
Dock 1 features a stunning brushed anodized aluminium casing and a natural black front of brushed aluminium for a sophisticated desktop aesthetic. The cradle on the left holds any compatible Hi-Fi Man digital music player (HM-802 HM, HM-901 and HM-901S) with a secure fit. A small series of round aluminium keys are used to select the music stored on the player, as well as music provided from the digital input on the back of the dock. The last of these buttons is for commissioning a buffer in the trajectory of the signal.
A well-presented, aluminium block remote duplicates the controls located on the front of the Dock-1 adding the search function to the front and the rear. The rear of the dock contains a base area equipped with a fuse holder, power-switch, three digital inputs, one USB B port and two S/PDIFs (digital and optical equally, but replicating digital signals from the player only). There is also an analogue stereo output on Cinch jacks, and a connector for connecting the battery charger of the player, which recharges it when it is connected to the Dock-1.
The greater part of the electronics on the Dock-1 take place on a main board mounted on the card buffer. This is inserted on two connectors with multiple contacts and is secured by two screws. The power supply is created from a beautiful toroidal transformer integrated on the main board. All the rectifier diodes of these voltages are next to two filter capacitors of 470F/25V, which are found with three other units on the opposite side of the card.
The various voltage regulators are all surface mount technology and are scattered on the circuit, positioned closest to the components that they charge with power. Installed as close as possible to the digital inputs and outputs, the impedance matches the transformers and the isolation of S/PDIF signals. Also, Sumlink ST-DV710 models are found next to the connecter, in order to connect the charger.
The buffer card uses Burr-Brown OPA627 operational precision amplifiers with very low noise production. Note that this buffer comprises filter elements (capacitors) and therefore does not provide a linear response. This dock produces outstanding sound quality enveloped in a full, warm soundscape by allowing a sedentary DAC to be used with a digital audio player.
When the HM-901 is inserted into the DOCK-1, its output voltage can be increased to 3v, which is similar to of high-performance audio components. With this increase in output voltage, HM-901 or HM-802’s sound stage will be enlarged, detail will be increased and high and low frequencies extended.
