I've spent a lot of time reviewing information on the forum. Hopefully this inquiry does not tax the patience of others. We're building a new home and having it wired for 7.1. 6.1 was standard, they'll do 7.1 for no additional charge so what-the-hey! We'll install 6.1 setup for now. The basic component list I've come up with is: Speakers A/V receiver calibration gear Wiring / connectors, etc. Expect to spend 2/3 on speakers 1/3 on the rest. Sound like a good plan? I'm confused as to where pre-amps and amplifiers come into play. I'm thinking the A/V receiver will perform these functions until I can tell the difference with better equipment, correct? Does the forum believe purchasing from sponsored vendors provides a better overall quality experience (product, service, price)? Thanks in advance!
