I might buy one of those pre-amp modules if it has the right I/O. Please let us know what the I/O is when available.
Think of it as just another "component" that you plug into your existing system like a Tuner/CD/DVD/BluRay/etc. It has a power button on the front with an indicator led, and around back there is a pair of left/right RCAs, a power jack for connecting a small "wall wart" power supply, two USB jacks for USB drives, and an Ethernet port. Volume control and source switching are handled by your existing pre-amp/receiver/processor/integrated amp. Inside are the same low noise power supplies, high resolution DAC, and Raspberry Pi2B as the AxiomAir portable.
Thanks,
Andrew
