The Echo Diastasis PH-79 Reference Zero negative Feedback phono preamplifier uses an original topology, which is the result of many years of research - the RIAA curve is implemented with two active stages that do not use global feedback. In active implementations, the gain at a given frequency is equal to the required one and no more.
