Alberto, Two audio files are available from by download area. They are 45 second recordings off 1233 kHz with a mix of several stations; France + Asians. Spectravue settings: AGC 2000 ms, hang 100ms, AM bw 6 kHz, LSB/USB bw -200/+3000 Hz (I don't like -200, it's too high but done for audio comparison with Winrad's 180. I prefer -100). Winrad: AGC Slow, AM bw 6 kHz, LSB/USB bw 3 kHz.
Please note that Spectravue's SSB audio level is a lot higher than Winrad's so one needs to compensate for that when comparing. I set the recording for similar AM levels. The recordings start with 15 seconds AM, followed by 15 seconds LSB and finally 15 seconds USB. (Few will note the shift from LSB to USB at 30 seconds without actually knowing it's there).
