I have a pair of Sansui SP5500X speakers. The best thing about these speakers is that due to their 15" woofers, they don't need a subwoofer. I have tested it with three different amps/receivers,

1.Onkyo HT-R410 5.1 Home Theater Receiver, (5X100Watts)
2.Sansui 777 Vintage 2 Channel Stereo Receiver (2X45 Watts)
3.A built-in amp that came as part of a Panasonic SA-AK300 Mini-Stereo System. (2X140 Watts)

Of the three I found the Onkyo lacking in volume and bass, and I didn't like the overall audio quality. The Sansui could drive the speakers as loud as Panasonic, but strangely enough, I preferred the overall sound the SA-AK300 amp over the Sansui.

Also the reason the Onkyo sounded so poorly may have been that it needed better optimization and also was designed for a surround sound setup.

Just my two cents.

When it comes to amps, I am of the thought that one should judge an amp by its weight.

All things being equal, the heavier the better.

The Sansui Receiver is by far the heaviest of the three. It is also is the loudest, but I still like the Panasonic Amp.
