If you're interested in imaging and the speakers' ability to make it sound like the musicians are in your room then I'd say throw out the spendors. The S3/5 have an inoffensive sound, but my ancient Spica Angelus made the s3/5 sound distinctly lo-fi ... not the result I was expecting prior to the demo. I used my densen b100 to demo the spendors so the same amp was driving the spicas and spendors. It wouldn't surprise me at all if a used pair of TC-50s beat the s3/5s.
According to their owners (I've never heard them personally) GMA Europas out-spica the spicas in their imaging and realism, so I'd say they are definitely worth a demo.
