The 66 series made a big splash in the nineties with its unconventional size, innovative technology and the symbolic Quad sound in a ultra modern package. This 66 preamp was the cornerstone of this stylish package. Although it has tone controls, its effects are not as invasive as some other preamps with tone controls. It offered some subtle adjustments which was great since it largely kept the original tone of the music intact. Phono input is pretty good considering its price point and overall, is one of the better mid-tier preamp in the sub-$2,000 category. Preamp comes with the larger, full system remote.
