Hello Mr. Duck, welcome, and sorry about your leg. But congratulations on your new AV room when the last kid moves out!
Let me preface this by saying I hope I don't come across as disrespectful. I am genuinely glad you stopped by and joined our obsession with audiophilia, and I hope you stick around.
There are some things that are impossible to describe effectively with text. What I recommend is to get out from in front of the keyboard and go to a brick and mortar high end audio shop (not a chain like Best Buy or HH Gregg, but some place locally owned). Take some music and maybe a movie or two with you that you enjoy. Tell them your Internet friends said they (the audio shop guys) could probably let you hear something amazing that you might not have heard before. Trust me, they love to show off and will be glad you asked.
These days, shaking the floor joists isn't terribly difficult. Such brute force is not even always desired. On the other hand, musicality and finesse, tonal clarity, accurate sound stage, an enveloping sweet spot... that's what I'd like you to hear. Unfortunately, my words can't do the emotion justice. It's the sort of thing you really ought to experience in person. There have been a lot of improvements not only to electronics, but also to speakers since your Cerwin Vega days. And if you don't hear what I'm talking about, then your current plan is a good one.
After all, it's the enjoyment and satisfaction with your setup that is the common goal.
In the meantime, be sure to configure your receiver to play those Pioneers as "small". With only a 60w max rating, I worry about bass leaking into the tweets and blowing them if you aren't careful.
In any case, we'd love to see pics of your system as a work in progress and when completed.
