Extremely low noise/distortion

Amazing clean/clear/neutral preamp for just about anything. There really isn't anything it isn't suited for, since it doesn't add anything that's not there already. Noise is vanishingly low, possibly the lowest noise floor you can get for under $1000. Low-output ribbon mics on a classical ensemble? No problem. Only trade-off is that there is no pad, and the minimum gain is +12dB. Usually not a problem in practice except when using condensers on a loud drummer.

The best IC/Op-Amp based Mic Preamp

Sytek manufactured the Neotek Consoles in Chicago. This is the same preamp that was used in the console. Steve Albini used these Consoles at Electrical Audio and they are superb.. These are great for Ribbon Mics or Overheads. The transient response is quick and the transformer-less design prevents your cymbals and hats from getting too "swishy" sounding. They have 70db of gain, Phantom Power(48v), Phase Reverse and a Mute switch. Many come w/Burr Brown Op-Amps as an added feature to channels 2&4.

Preferred Settings + Usage:

6 on a passive Ribbon and 3.5 on Overhead SDC Microphones
