Wow, yesterday my friend and I went to a local home electronics store (hint starts with a U) to get him a simple reciever. He is going to use it to power a pair of 4pi theater series speakers www.pispeakers.com that we will finish building tommorow. So we get there, and the salesman comes in the room. We tell him which reciever we want. He then tells us to check out the open box specials. We do so, and he says stuff about how Yamaha is better and such. I ask him to explain how, but he cant. So another salesman comes over and starts asking us questions. We tell him what the reciever will be used for. Then he makes the claim that if we up the money we are going to spend, we will get an increase in sound quality from the reciever! So I tell him flat out that I have never heard a difference, and he says he can prove it to me. So we go back in the room and he picks out two recievers, a Denon and a Yamaha, both around 500 dollars. He switches between the two and is like, cant you hear a difference? He says the Denon sounds less tinny than the Yamaha. Im like, well I cant hear a difference, EXCEPT ONE IS LOUDER THAN THE OTHER! I ask my friend and he says the same thing. I then ask him why the amplifiers should sound different, and he says "different circuitry". I start asking about the amplifier design topology, and he says he doesnt know all the technical stuff. So then he says, why dont you believe amps make a difference? I tell him that Richard Clark has a 10 thousand dollar test if he can hear a difference. Then he asks where Clark lives. I tell him. Then I tell him that anyone who is an engineer who works with amplifiers KNOWS that there is not a difference in SOUND QUALITY. I then tell him that people are running the same speakers my friend will be with 8watt tube amplifiers, so any consumer level reciever will put out enough power to get his speakers over 115dB 1m. So finally we are ready to go, and get to the counter to check out his "crappy" 200 dollar Panasonic reciever. The next thing that happens I almost have a heart attack. The first salesman is asked by another salesman what the reciever will be used for, and he tells him, a pair of PA speakers. The other salesman says the amplifier will melt from THE IMPEDENCE OF THE PA SPEAKERS, yet he knows NOTHING about what speakers we will be using. I just give up, and tell him no, the amplifier will work fine, if it works with SET amplifiers, the transistor based amplifier will work just fine. I want to go back to the store, and make a fool of that salesman who told us that the amplifier will melt. God, what comission will do to some people. Cliffnotes: Consumer Retail stores have a staff on hand that know nothing.
