Working at a Dealer that sells both the PSBs and the Meadowlarks, I would recommend either as a great speaker. I do not have any experience with the Europas. The PSBs are a bit more forward and have better bass extension. They have great tonal balance but tend to bit a little less "deep" in soundstage. The New Kestral 2s soundstage live a bandit and have that "touch" of warmth that you say you like. Not as much slam in the bottom end but VERY well balanced bass for what the do put out. Your 762 should drive either very well unless you have a huge (read 30 X 30) room or want to put a real hurting on your eardrums. Just my 2 cents. Best suggestion is to audition all you can and let your ears decide.
