I recently took in a floor model SA-3 and I'm already planning on returning it. Firstly channel 2 was cutting out, so I opened it up and found that it was just a loose ribbon cable connection. Second, the first channel upfader started crackling, so I air blasted it and lubed it. Then as I started mixing. I noticed that the fade curve on the upfaders were terrible and the volume output was considerably low. Although I will say that the quality of the sound was way better than my Vestax. Its one good looking mixer, but the internals were so cheap, the faders looked like they were built in a middle school electronics class, connections were very sensitive and were hot glue gunned for extra "reliability" Before trying this mixer out, I already had a bad experience with a factory defect found on the mixer that came with the old Stanton Platinum Pak 2 (it was an SK something). I love my STR8-80s, but I have no confidence with Stanton mixers. Hmmm next!
