Some background:
I have not heard the Studio 20 but heard a lot of Paradigms (small book shelfs through the S8) and have heard the RB-61s number of times. I have directly compared some Paradigms and Klipsch speakers back to back. I was helping a friend put together a surround sounds.
On Power:
You have enough power for either speaker. The Klipsch will be MUCH easier to drive. The Studio 20 is 89dB/2.83V/m and the Klipsch are 95dB @ 2.83V / 1m.
For every 3db less of sensitivity you will need double the power. So the Klipsch will take about 1/3 the power of the Paradigms to achieve the same loudness. If I had to guess the Klipsch is only going to used about 7-10 watts at normal listening volume. Maybe someone who knows more could calculate it for you (or google it).
Sound:
Both are good buys and it will come down to personal preference. For music I like the Paradigm (as a brand) better. The mids are warmer and more natural. The advantage of the Klipsch is the sensitivity and dynamics. They have very good bass for such small speakers. The Paradigms bass is good too (reletive to the size of the speaker) but the nod goes to Klipsch for me. Klipsch are nice for surround sound because of the dynamics.
Anyway listen and choose what ever one you like best. If it were my money I would buy the Paradigms for music and Klipsch for surround sound.
