I agree. It stands to reason that the fewer "transmission medium" transitions a signal has to make before it reaches the actual speaker driver -- to spell it all out for you: circuit board inside the receiver to speaker terminal on back of receiver to speaker wire connector to solder to copper wire to solder to speaker wire connector to binding post on speaker to solder to internal copper wire to solder to crossover circuitry to solder to copper wire to tweeter/mid/woofer -- the smaller the chance there is of degrading that signal.
It doesn't matter WHAT connector you use, since it cannot -- in and of itself -- improve the sound, but can possibly make it worse. The best connectors should, by definition, do NOTHING to the sound.
Using this same logic, the best connector is no connector. A tight (and some might say de-oxidized) bare-wire connection is as good as it gets.
