The technical basis of all Professional Fidelity units is our proprietory 120 V Rail Technology, which we also call VOLTAiR technology. The name makes reference to the unequalled high voltage of 120 V (+/-60 V DC) and the huge dynamic range of over 140 dB that goes with it. More information on the 120 V Rail Technology can be found here.
“When I do re-mastering of old pre-CD titles we always try to get a copy of the originally issued pressing so we can hear what the artist approved, not someone else‘s idea of it on a CD made years later!”
