This Grace Design m501 has been fully tested by our expert team and comes with a money back guarantee and lifetime support. We have multiple units from the same production run if you would like a pair.

The Grace Design m501 is the 500 Series incarnation of the company's acclaimed m101 — a preamp built for engineers who want to hear exactly what their microphone and room are doing, without editorial comment from the gear. Its balanced, transformerless transimpedance circuit prioritizes vanishingly low distortion and an exceptionally wide frequency response, making it one of the most transparent options in the 500 Series format. A dedicated ribbon mic mode raises input impedance, bypasses coupling capacitors, and locks out 48V phantom power to protect passive ribbons — and it works equally well with low-output dynamics. A front-panel Hi-Z instrument input, 75 Hz high-pass filter, and 48V phantom round out a focused, no-nonsense feature set. Hand-built in Colorado and backed by Grace's legendary 20-year warranty, the m501 is the right tool when the goal is capturing the source, not coloring it.
