Product information "AEA RPQ503"

The RPQ503 is the next evolution in AEA's proven line of high-impedance, high-gain preamplifiers. Based on the third-generation circuit design of our renowned RPQ3, the RPQ503 brings the same rich, natural sound to the 500 Series format. It features a powerful combination of ultra-low-noise, low-distortion op amps, extremely high input impedance of 68 kΩ, and 85 dB of clean gain—delivering exceptional clarity and detail.
