Here is what I'd do if I was starting all over:
Buy a secondary set of speakers first for about $1000-1500. I'm thinking you can find a place for a second stereo in the new home...maybe your bedroom?
Get something like the KEF ls50 or Philharmonic Philharmonitor (my preference) - these are physically small enough to look fine is a smaller room, but they offer very good sound, are generally considered neutral, and will work in a good sized living room at normal volumes.
For now, use this as your primary system. Go ahead and get your SVS PB13Ultras since you have made that decision. I'd suggest that you get something like a Marantz SR-6010 to hold you (it will manage the dual subs with XT-32).
This will give you a system that most of us would be very content with.
The idea here is you now have a very fine system. You can fit this in your current home so you don't need to wait, but most importantly, you can gain experience:
1) The speakers I suggest are neutral - neither overly forward nor laid-back. This will give you a basis for evaluating other speakers. If you have not been around high quality audio, it is easy to go into a showroom and be blown away by speakers that offers so much more than what you are used to! You need to "refine your palate" by listening to quality speakers! We can recommend speakers that are overall very good and good values, but we cannot recommend speakers that will sound best to you.
For example, consider Klipsch. In my experience, they are forward sounding speakers (but I have not heard the Palladiums). For me that makes them exciting speakers - I use a set of RF-82ii's for my HT. However, I do not use them often for music. I play in a jazz band and can say that my Klipsch make a trumpet (for example) sound a little brighter (or maybe just closer to my ear) than it should. They are not bad for awhile, but over extended time they can wear on my ears.
I have met people that love this sound and do not experience the listening fatigue and others who are quickly turned away by the brightness. That is why we cannot properly tell you what speakers to get.
2) Modern AVR's are incredibly complex with menu systems that go 3-4 levels deep. I think it is worthwhile getting started with one and using it as a reference for what you do and don't want. Something like the SR-6010 has many features and is a great overall unit, but not physically imposing when you move it to the second room. In my opinion, this AVR will work fine as your primary AVR (the need for external amplification depends on the speakers ... or if you just want an amp just because you can).
You also might consider going to the Rocky Mountain Audio Festival. The info for the 2016 one is not out yet, but you can Google "2015 RMAF" and read over some accounts of last year's to get an idea of what it is (just don smoke any "legal in Colorado" pot before you choose your speakers - they might not sound the same in your home sober)!
