The only missing info is the maximum impedance it can be driven from.  There is a big difference between the measured response from a 50Ω 600Ω and 10kΩ step-up.

During the last 10 years Sophia Electric has utilized all its transformer making skills and ingenuity to solve these challenges. We have used the latest science and exotic high tech materials to bring you the ultimate in-line transformer amplifier device - Magik Box.

I'd generally be rather skeptical that noiseless gain of 6 dB at line level can do much of anything to improve sound. Their claims are quite ambitious. They even claim it improves (or have in the past) the sound from MM cartridges when placed between it and the phono input. Seems the impedances there might be an issue.
