The ones I used are the WMH series, which are aluminum foil and polypropylene film capacitors, and made to compete
directly with the highly regarded Jantzen Audio Alumen Z 100V capacitor, almost the exact same dimensions, but at a much lower cost.
The left (upgraded with WMH) side sounds more like it is in stereo, more depth with natural ambient cues, more height sensation,
instruments and vocals in their own space, whereas the right is a flatter sound, everything gets a little bunched up,
it's a lot more obvious that only a single speaker is playing.
