I'm into more modern stuff, but got to keep an open mind. Already ordered it. The Webster renaissance is $55 on amazon used and $300 new, so I'll pass on that one.
that Webster recording is 'live' and should be played at warp 9 if possible, that horn should startle and then levitate the listening experience, just like live would. it is a litmus test for amps in my mind as if an amp cannot grip the speaker sufficiently to propel that music then what other essential micro dynamics is it not doing? it's not exactly a power issue so much as a synergy issue. the 'jump' factor.
I can tell you with 100% certainty that your speakers do that music wonderfully.
Ben Webster's music is so significant to me that I named my 'network' in my home Webster. if I had a dog it might be named Webster.
