I run the Winamp DSP bridge for foobar2000 to host the ST DSP plugin. I feed ST at -6.2dB to keep out of the bridge's hard limiter, which in turn I use as headroom for ST to declip, add dynamics, and similar. I run all the above under Wine. Thankfully it works okay as foobar2000 is one the few Windows apps I prefer.
I mostly use foobar2000 for background music, so the Winamp DSP of ST is fine there. I can pipe audio through JACK to the ST standalone for more serious processing if needed.
ST 10.x running in a 2c/4t config on my AMD 5700u 8c/16t notebook suffices for my DSP playback config, though note I tend to shy away from AGC and multiband compression for playback since I am more interested in restoring dynamics for that particular role. ;)
Otherwise bumping to a 4c/8t config tends to handle pretty much whatever DSP config I throw at ST; perhaps short of cranking audio processing quality up to 150%.
