I have tested three winamp dsp plugins for surround sound / 24bit stereo / 24bit surround output in winamp:
Enhancer v0.17 (generates noise / No sound processing / no sound processing)
iZotope Ozone For Winamp (no sound processing / works normally / no sound processing)
DFX v8.325 for Winamp (processed surround sound output / works normally / processed surround sound output)

Used Winamp v5.34.1239 beta (directsound output with hardware acceleration nedded for surround output and "Allow surround sound" in playback settings, to force 24bit output in winamp tick "allow 24bit" in Playback settings).
Audio source was "Mai-Otome Zwei - 02" (16bit 48kHz AAC 5.1 audio track)
Creative SB Audigy 2 ZS in quad speaker setup (CMSS was disabled to avoid creation of artificial surround from stereo source)

Anyway I think that Winamp only outputs audio in mono, stereo and same as source (like 5.1) even if you have quad speaker setup selected.
Maybe you should add a button in ffdshow winamp dsp tab like in winamp playback settings, "allow surround sound", to enable or disable dsp surround sound processing if possible.

Here's a pic of DFX processing surround sound in winamp.
