Carver C-4000 High Fidelity Control Console Preamp

From hifiengine.com:

At its heart the C-4000 is a high performance console preamplifier with precise RIAA phono equalization, low distortion, high slew rate, wide dynamic range, and a high degree of control flexibility.

But its similarity to other fine preamps ends there. The C-4000 goes far beyond mere accuracy and fidelity: it's goal is a dramatically higher degree of realism than has ever been achieved before in audio reproduction.

Thus its Peak Unlimiter undoes the dynamic compression which makes many recordings and broadcasts sound canned.

It's Auto Correlator noise reduction system strips away the veil of low level rumble and hiss which form a perpetual psycho acoustic barrier to realism in the reproduction of musical timbres.

And its Time Delay and revolutionary Sonic Hologram Generator break through the limits of listening-room acoustics and the two channel stereo medium itself to provide a remarkably three dimensional you are there realism, with a sonic image which subjectively extends far beyond the loudspeakers in both breadth and depth.
