Speaking of operatic voices, this is most of what I listen to. And many of those are of the vintage and historic variety. The transfers from the first electronic microphones in the 20s, even when updated by the best engineers, leaves much to be desired in terms of today's recordings. Even the best are still mono. I have walnut STs coming any day now and I ordered these because of their reputation for accuracy and clarity of the mid range.
I am now wondering if many of these old recordings will sound better or worse with such accurate speakers? Tenor voices could be the most problematic. Has anyone played Gigli, Bjorling, early diStefano and moving up to the 50s, Mario Lanza, who at least did make a few stereo records? If so, how do these recordings sound on the STs, both in the original vinyl records as well as CD transfers?
