The PQ-303, PQ-505 and PQ-707 are three new energy merchandise from AudioQuest that stretch the corporate’s PowerQuest line. Every unit places twelve shops in a full-width field to take a seat in a hi-fi rack (like every other audio part) or be fitted to a house set up rack with the optionally available “2RU rack ears”.
Of these twelve sockets, eight are noise-filtered; and are supposed for connecting fixed present supply elements like TVs, CD gamers, community streamers, DACs, turntables and phono levels. The 4 unfiltered ‘high-current’ sockets are for connecting variable present elements like energy amplifiers, AV receivers, subwoofers powered loudspeakers whose dynamic efficiency would in any other case be constricted by noise filters. Suppose: snorkeling with a ingesting straw.
Noise filters? The PQ-303’s eight noise-filtered sockets take intention at any differential mode noise (from 30kHz to 1GHz) piggybacking in your listening room’s mains energy provide. Differential mode noise, in accordance with AudioQuest, is often generated by washing machines, ovens, lights, vacuum cleaners and fridges whose energy provide noise can backwash noise into the constructing’s mains provide. Sure, that backwash may even come out of your neighbours!
The PQ-505 provides common-mode filtering (from 30kHz to 100MHz) to its arsenal which strips out the noise generated by cellphones, Bluetooth transmitters, wi-fi networks and radio indicators that may leach into our energy cables. In keeping with AudioQuest, all cables, together with energy cables, act as antennae to a lot of these airborne noise.
The PQ-707 ups the ante by providing wider-bandwidth differential mode filtering than the PQ-303 and PQ-505 by taking place to 8kHz as a substitute of 30kHz.
However that’s not all.
The PQ-707 additionally options one thing referred to as a Transient Energy Correction (TPC – pictured above) reservoir the place an inner ‘supercapacitor’-like gadget can instantaneously ship as much as 45 amps of energy to your energy amplifier, AV receiver, subwoofer or powered audio system ought to the music demand it. As some extent of reference, a typical wall socket will prime out at round 15-16 amps. TPC’s additional non permanent present supply (for as much as 25ms) could be helpful for higher controlling a track’s huge bass moments and/or making extra expressive its dynamic peaks.
All new PowerQuest fashions characteristic “non-sacrificial” surge safety and can robotically shut down if greater than 140VAC is detected on the incoming AC line for greater than 1 / 4 or a second. A removable 2m PowerQuest cable is equipped with every unit.
Pricing? The PQ-303 will promote for US$459.95, the PQ-505 for US$699.95 and the PQ-70 for US$1299.95. Be aware: these are US-only fashions fitted with ‘Edison’ sockets. The European and UK variations that require Schuko and the ’13 A’ sockets respectively will comply with sooner or later.
