I have no idea about the their power cables, but an hour ago I installed their digital cable with magnet upgrade. Total cost was $200 for 1m.
It has been the most signifcant system upgrade I have ever done. Certainly better than any other cable upgrade, whether it be power, speaker, coaxial or IC.
Mojo Audio claim this digital cable competes with those at 2k price range. They are not joking. Compared to my other digital cables, they have smashed this one out of the park.
Mojo Audio's speciality seems to be power cables. If their power cords are at the same level as this digital cable, then they know what they are doing.
