Overview
AudioQuest PowerQuest 505 is a high-performance power conditioner with 12 AC outlets (4 High-Current outlets for amplifiers and 8 Linear-Filtered outlets for source components), a 2m detachable AC power cable featuring ZERO-Tech and RF/ND-Tech, and 2RU rack ears for simple rack-mounting. Engineered with advanced power filtration, the PowerQuest 505 removes significantly more noise and distortion than typical power conditioners, helping your system perform at its best. With non-sacrificial surge protection, the PQ-505 goes beyond traditional surge protectors. It safeguards against high voltage and current, preventing damage to your equipment and ensuring the device’s long-term reliability. The Extreme Voltage Shutdown feature activates the main power circuit relay in less than 0.25 seconds at 140VAC and automatically resets once power returns to a safe level. Built to endure rigorous 6000V/3000A input surge tests, the PQ-505 can withstand multiple surges at the highest level that a building’s AC panel can survive, offering reliable protection without components wearing out over time.

Where is your showroom?
We're at 6362 Alder Drive, Houston, Texas. The showroom lets you hear and compare reference-level systems in person before making any decisions. If you're considering a larger purchase or installation, it's well worth the visit.
Can I buy online without visiting the showroom?
