I'm currently in shopping mode for a new receiver, having arrived at the conclusion that it's time to retire my Onkyo 484 to the bedroom. After demoing a Yamaha RX-V1200 and Denon 2802 last weekend, I wanted to hear a H/K AVR 520 or 320. Unfortunately, the only local place that carries Harman/Kardon that I know of is Cambridge Soundworks. So I sucked it up and went to my nearest one, but all they had set up in the listening room was a Marantz 5200 and Onkyo 989. When I asked if they would hook up either a 520 or 320 for me to demo, the sales people told me that they "don't do receiver demos"! Why? Because "you can't hear the difference between receivers"! At this point, I asked them to let me do a blind test of the Marantz and Onkyo. The guy was skeptical, but agreed because he was sure that I'd make a fool of myself. They had TPM playing the climactic Obi Wan vs. Darth Maul scene. After a couple of minutes of the sales guy switching back and forth between the receivers, I was able to easily identify better sound coming from one of the two. Unsurprisingly, it was the Onkyo that sounded better (don't know if it was $2500 better, but that's another post). After this, the guy back-peddled and said that he could hear the differences that I was pointing out and also claimed that he could hear the difference between Sony receivers and those made my "true audio companies". So, the end of the story is that I managed to educate (however slightly) a CSW employee, while leaving with no better idea of what the HK 520 sounded like. No wonder the mass HT market is in a shambles.
