If your Levinson amp has over or 100 WPC,I would suggest the B&Ws 801 series 3,a bit easier to drive than the series 2.Has very good and tight bass and nice silky mids and highs,if you fell that the amp cant drive these speakers i would definitly suggest the B&W 802 series 3.Why I have a pair and they do the job very well,I was using Conrad Johnson MF-200 and Premier 3 pre,but got an offer on the preamp that I couldnt refuse.You might want to try out the MARTIN LOGAN speakers,I had the SEQUELS and they sounded great with rap and R&B,soul music.The Martin Logans can handle it too.Also you can check out the B&W NATILUS speakers too.More looot but definitly worth a listen.Try listening to those speakers and decide.Its nice to know that you like tubes in the pre and S/S power,it's a nice combination.Good luck on your search.
