Good starter speaker

Hello,

I am currently planning out a 2 channel system and I already purchased a used Rogue preamp.  The audio visual store that I like to deal with has a trade up program for speakers as long as the trade up is twice as much as the original purchase, which I’m fine with.  I am trying to keep the budget as low as possible at this point.  Here are the speaker brands that they carry:

Aerial Acoustics, Audio Engine, B&W, Emotiva, KEF, Klipsch Heritage, Klipsch, Linn, Martin Logan, Paradigm, Paradigm Persona, PSB, Soundcast, Spendor, SVS, Terra, Totem Acoustics, Totem Element.

Where would be a good place to start knowing that a year later I can upgrade without losing my initial investment?  Also, any suggestions concerning a powered amp in the 700-1500 range would be appreciated.

Thanks,
Roland
