hello I have done a lot of reading on this forum getting information before purchasing much of my vintage equipment but this is my 1st post. I just picked up a SX-450 from goodwill for $19.99. I am greatly amazed at how this thing sounds with only 15 wpc, I have it paired up with Klipsch kg 4s and the sound is amazing. I own a g9000 that is getting a full rebuild and a Onkyo tx-nr 727 for movies but will be using the 450 for music while waiting for the Sansui to return home. Thanks to everyone here for all the valuable knowledge you provide.
