I'm after some advice on which model paradigms to buy. Currently I have a 5 medium quality speakers running off a Nad 752 (which I've had no problems with). I'd like to retain the 752 for now, but replace the two fronts with some very good sounding stereo speakers for my music. Eventually I'll replace all speakers and get a bigger amp (like the NAD 773). After a lot of research, I've narrowed it down to paradigm 20's v.3, or paradigm 60's v.3. The 60's are exactly twice the price of the 20's, and will exhaust the budget for now. I've listened to both, and to my ear, I couldn't detect much difference in the mids and highs, but I noticed the fuller bass in the 60's. I also much prefer the look of the 60's, as my lounge is medium/large and the 20's are going to look fairly ordinary in the middle of that room. The advantage of the 20's would seem to be the 'bang for buck' and as I'd have cash left over, I could buy a good sub to go with them, which would work out slightly less than the 60's by themselves. What I'd like advice on, is whether the 20's with good sub will outperform the 60's (with or without a sub) and also whether the Nad 752, rated at 150w at 8 ohms in two channel mode, is going to be able to drive the 60's as an interim solution.
