Amplifier:	Built into all speakers. Chipamps in monitors and a 200 watt Tripath in the subwoofer.
Preamplifier (or None if Integrated):	None, move plugs to change sources.
Speakers:	Quad 11L Atives. Rebuilt amplifier modules, with beefed up power supplies, better connectors and TL072 opamps replaced with OPA2134. Final Sound S220 used to filter the bass and feed the Quads. Line out is fed to the Final Sound S220 Subwoofer. It filters out the bass < 70 Hz and feeds the filtered high pass to the monitors. Surprisingly, the sub does not seem to hurt the mids and highs. The monitors seem to like the filtered feed better than the full range.
