I was intimately familiar with the Sonus Faber Guarneri Evolution speakers $20,000/pair), with their matching stands ($2000/pair), in one of Listen-Up's rooms at RMAF, having measured them two days before I left for Denver. (Art Dudley is reviewing this little jewel of a speaker in the January 2012 issue of Stereophile). At RMAF, they were being bi-amped with four PrimaLuna DiaLogue 7 tubed monoblocks ($5499/pair) with AudioQuest cable, Preamp was the PrimaLuna DiaLogue 3 ($2699) and while a PrimaLuna ProLogue Classic CD player ($2999) could be seen. this had been broken in shipping and CDs were being played on a Simaudio player.

From my listening notes, as I auditioned the classic Chet Atkins-Mark Knopfler gittar-pickin' duet "There'll be Some Changes Made": "maybe a little too rich-balanced but a good sense of pace and impressive low-frequency extension for such a small speaker...unaccompanied female voice had a beautifully liquid quality with space space space!"
