Floor Standing under $1000 Polk vs Paradigm

I have owned both the Studio 60V2 and the LSi-15. Up front the Polks are much better speakers IMO. Bass is the only area where the Paradigms beat the Polks. In every other category, the LSi-15s excel. The tweeter Polk uses is phenomenal for the money, especially at used price, while the Paradigm tweeter is somewhat fatiguing. For reference, I've also owned Vandersteen 2CE Signatures, Meadowlark Audio Shearwater Hot Rods, Eminent Technology LFT-8As, as well as a few well respected monitors, and the Polks are the best sounding speakers I've owned.
I'm sure there are many suggestions but if it's between the two mentioned, go for the Polks.

I was really surprised how good the Polks were---a friend bought the $700/pair floorstanders and i thought totally outclassed the Paradigms---very coherant top to bottom which is unusual in a speaker of that budget

IMO, the Polk LSi's are definitely the better of the two in question. However, you're not going to get all of what they are capable of with your current power source. Feed them well and they will reward you.

I used to own the Polk Lsi 15s and they are great for the money and easily best the Paradigms,but up to 5k thats some pretty strong words,infact the Salksound Veracity Ht-3s will obliterate the Lsi 15s or anything anywhere near that pricerange and signicantly above.

Merganser,
So how much power am I gonna need? Can I use my current amp with decent results until I can afford to replace it. It might be while until I can do that. If it is gonna sound like crap with my current system and the Polks I don't think I can go for that.
