Audyssey Sound Equalizer (SE) removed from client's house. He was the original owner.
Kal from Stereophile reviewed it and this is what he had to say:
"Description: The Sound Equalizer is a slim, clean, compact box about the size of one rack-space (about 1.75" high). Its front panel contains only one control and two LEDs. One LED indicates that it is powered; the other glows red when MultEQ Pro is off, green when on, as toggled by the switch. The rear panel has a main power switch adjacent to the IEC AC inlet, RS-232 and USB ports, two test ports, and two sets of eight RCA jacks each, for up to eight channels of input and output."
"The SE has twice the resolution of built-in versions of MultEQxt over most of the audioband, and eight times as much in the bass."
"The Audyssey Sound Equalizer with MultEQ Pro genuinely enhanced the sound of my system. Once it was installed, I could simply leave it alone and enjoy a more transparent and coherent soundstage."
Note: calibration of the Sound Equalizer requires the professional installer's kit...available from http://www.shop.perfecthometheater.com/Audyssey-MultEQ-Pro-Calibration-Kit-Audyssey-Kit.htm for $550.
