OK, lots of good speaker advice. Just keep in mind the whole picture, make sure you set some funds aside for the upgrade from the Technics receiver. Some of the speakers recommended above, such as as the Triangle Titus, are great, capable of the real magic. But they will sound horrible with a regular receiver. Also, the source, whether a disc player or a music server/dac is very important.
Best of luck to you
