It's not all black and white. There's a balance to me had.
Work with us, guy. First you throw out all these of the wall, apples to oranges prices and now you say that your budget is only $1000. Make up your mind.
Choosing a system is almost a black art.
First, you decide on the speakers you like. Since these will have the most affect on what you hear, you should choose these firstand be a little liberal with the dollar allocation. It's not unusual for speakers to cost at least as much as all the other components in your system.
And, a $100 sub is almost guaranteed to disappoint.
Now that you have an idea of what speakers you like, you go about selecting a receiver that has the features you NEED and also has more than enough power to drive your speakers properly. Sme features and real, clean power can cost money.
Once the balance between these first two is met, you'll find that yoursource component budget may be less than you expected but remember, DVD players are available for a song and since you're using the DAC in your receiver, these are more less a commodity.
As for your cables, check out Home Depot. ...seriously.
