AudioQuest PQ-303 PQ-505 and PQ-707 stabilizers received Niagara technology

AudioQuest has expanded its PowerQuest family of power conditioners with three models. It is claimed that all of them are fueled by the “critical DNA” of the products of the flagship Niagara line.

The new products themselves can be classified as a completely budget class, but at the same time they provide “linear noise dissipation and reliable surge protection.” The new products don’t care about AC surges up to 6,000 V/3,000 A; when the voltage goes beyond the permissible limits (both up and down), they automatically turn off.

Three new Stabilizers are made in a “rack-mount” form factor and are equipped with appropriate mounts. Linear noise dissipation in the younger PQ-303 occurs in a differential filter in the range of 30 kHz - 1 GHz. Older models also have a common-mode filter with an operating range of 30 kHz-100 MHz added to the circuit. The older PQ-707 also has a storage capacity.

Each of the three stabilizers is equipped with a two-meter removable power cable with adjustable direction, which further dissipates radio frequency interference.

In the US, prices for AudioQuest stabilizers are as follows: PQ-303 - $460, PQ-505 - $700 and PQ-707 - $1,300.
