Both are excellent speakers, worthy of any fine audiophile system. I now own the VR4 III HSE, and they replaced the Focus (not the 20/20s though).
In summary:
Bass - Better on the VR4s, tighter, less boomy, more punch, easier to control.
Imaging - Both excellent
Highs - Both Excellent
Soundstage - Focus had a taller soundstage, the VR4s have a wider soundstage. Depth was good on both.
Finish - Focus were much nicer
Mids - Both were excellent, VR4s slightly warmer, more natural to me.
Sweet spot - This is probably what did it for me, the VR4s have a better, wider listening angle, the Focus were very narrow (1 person).
As they say, your mileage may vary based on equipment that you're using, but this is what my system produced.
Regards,
Mark
