This unit was used briefly in a review. It has under 50 hours of use and likely has not fully broken in. The Smarthub like a dac uses a clock and requires a period for break in. The unit carries the full one year warranty.
Units are offered with 30 day money back guarantee, minus shipping costs. Always audition gear to ensure it is right for your system.
The Waversa Smart Hub has four internal Lithium-Polymer batteries where the Ethernet and USB hubs are isolated from both the external power supply and each other. This eliminates the need for an external linear power supply. The battery bank has two designated batteries for each hub and is monitored continuously, automatically switching to the newly charged battery and recharging the depleted battery. The manufacturer predicts a Lithium battery lifespan greater than 2 years; therefore, there is no need to turn off the Smart Hub when not in use.
Like all Waversa products the Smart Hub is easily serviced by the end user, allowing battery replacement when appropriate. If both batteries are discharged, the hub automatically seamlessly switches to the external DC input and recharge both banks simultaneously. Also, if the DC power supply is disconnected, the battery packs discharge sequentially.
To further decrease cross contamination, the Smarthub is designed with three independent CPU’s. Ultra low power micro controller processes the signal while external DC input is disconnected. Micro controller for front panel is completely isolated preventing contamination by extraneous noise produced from LED display. Also the LED’s used to display data movement in generic Ethernet switches is eliminated altogether. Finally, ARM AP is the fifth Ethernet port and is internal. This controls the user interface, allows automatic IP assignment by the router and firmware updates.
The USB hub is placed between the server and the DAC while the Ethernet is placed between the NAS/Network and the Server/Renderer. The incoming signal current is isolated, while the data is translated to codes and generate new packets of data sent to different ports where each port has filters to eliminate noise. Total of 16 filters are in place to accommodate the 4 Ethernet ports. By removing this extraneous electrical noise the sharp edge often noted in high frequency audio signal no longer is present giving the overall impression associated with a vinyl system.
All digital signals, be it over LAN, USB or I2S, has rising edge and falling edge and is based on master clock. If master clock is not accurate then rising and falling edge is not a constant distance and this variation, also known as jitter, causes high frequency noise. If clock is accurate enough and supply power is clean then hub regenerated digital signal does not contains wide spread noise. Waversa uses its own proprietary MEMS clock that is over spec for the Ethernet and USB communication. This is the same clock used in the DAC3, thus creating an ideal pairing of components, creating a certain synergy that has been unanimously commended by those who auditioned them.
