Surge Protection and Linear Noise Reduction for Less: AudioQuest PowerQuest 303 Power Conditioner Features 12 Outlets, PQ-415 Power Cable, Class-Leading Performance

Delivering class-leading performance and offering excellent protection at a price point that lessens the cost of entry from its reference models, the AudioQuest PowerQuest 303 power conditioner is an ideal power solution for listeners with entry-level and mid-tier high-end systems. Equipped with 12 outlets — four high-current types for amplification devices and another eight linear-filtered outlets for source components — PowerQuest 303 provides both non-sacrificial surge protection and extreme-voltage auto shutdown to guard against potential disastrous outcomes that could ruin your equipment. 

Better still, PowerQuest 303 adopts AudioQuest’s comprehensive power conditioning philosophy — addressing noise linearly to give you wide-bandwidth noise reduction that impacts the high, mid, and low frequencies. Weighing just 10.24 pounds and measuring a scant 3.5 x 17 x 13.4 inches (HWD), this high-value component even comes with an AudioQuest PQ-415 power cable with a flat-to-wall plug and seven-strand long-grain copper. Also in the box: Rack ears for mounting applications. Set it and forget it? Indeed. 

If you want to hear more music — and less interference, distortion, and gunk — and give your gear intelligent protection, you can’t really do better at this threshold. Learn how you can audition PowerQuest 303 in your own home risk-free — or simply learn more about the unit itself — by calling a Music Direct audio consultant at 312-433-0200. 

“This could be the AC hub of a reasonably sized system with the security of linear noise dissipation filtering, designed by a real power-delivery expert, AudioQuest’s Garth Powell.”
