The Sound Dynamic 300ti loudspeakers, in my opinion, outclass the Paradigm 20's in every way. However, finding a pair of 300ti's on the used market will be difficult. I am pairing the 300ti's with some very high class electronics: Museatex CDD-1 transport, Theta DS Pro Basic II (fully balanced) DAC, CJ PFR preamp, Ayre V-3 power amp.
