Single-channel, ultra wide-bandwidth preamp with special ribbon mic mode provides remarkable transparent audio quality.

In 2000, the Grace Design model 101 microphone preamp helped fuel a revolution. When people took professional recording into their own hands, it was there with all of the quality and performance of a high-end mic preamplifier, but with a price that made it available to the masses. 8 years later, and the cause moves forward with the newly redesigned m101 preamp.

With its impressive list of new features, the m101 is ready to give any mic preamplifier a run for its money. Consider the new audio signal path with 0.5% precision metal film resistors, 12 position gold plated rotary gain switch, a built-in universal AC input module, or our exclusive RIBBON mic mode, and the picture becomes clear: This is now a fully professional, state of the art precision mic preamp that roundly outperforms anything in its class. All this at the same affordable price of the original model 101.

Note: For a truly outstanding sound and value, we suggest using the Grace m1011 with the CAD e300 condenser mic (see (#271261) for amazingly clear and detailed, yet warm-sounding vocals.

This review is going to read like a press release from Grace Design, but I swear I have nothing to do with the company. Anyhow. Holy cow. This thing is awesome. It was a good value before the new model came out but now they have added an unbalanced out and a ribbon button. Also the wall wart is gone now. If you need a good clean low-noise preamp you are looking in the right place. Everything works perfectly, there is absolutely no noise even with space heaters nearby, and it's a nice rock solid build too. I cannot recommend this device more highly.
