Ok here is another question then.....
I went to the following:
Marantz dealer (SR-7500 - rated at 105W)
Yamaha dealer (rx-v2500 - rated at 130w)
Intergra Dealer (6.3 - 100w)
Both the Marantz and integra dealers said that for each of the models i was looking at, the wattage (while lower) would actually out perform the mass-marketed receivers (such as the Yamaha), would sound cleaner, louder and in the end have more power. Of course these are sales guys and they say that while the Yamaha will put out maybe 35-55 watts, the other 2 brands are more conservitative. Then they get into size of power supplies, heat sinks, etc. Truth is looking into the top of all units, they look, feel and weigh about the same. ..
Any truth to all of this?
