I like Sansui speakers. I have many pairs, and one thing I have noticed, for sure. If you run anything other than Sansui source amplification, there is a big difference in sound. These speakers shine on Sansui receivers, Pioneer? Not so much. I'm running SP-2500 and SP-200 on a 9090db, and they sound great. I've switched out with 4311B and L-100 just to play around. The JBL sound great on anything I've put them on, kinda like the Sony SS-TL5. Even with an eq, the Sansui just don't shine on anything else like they do their own. I've not re-capped yet - that's next, just to satisfy my curiousity. Because the SP-200 I have, are the exception. They sound good on anything I've put them on.
