@Redcarmoose: Interesting points made sir! While the K10s sound just as great now as they did upon auditioning them, there is a lot more being discovered every day (especially if I play something from The Rolling Stones, Daddy Cool, The Beatles (incidentally Paul McCartney’s Band on the Run was not well mastered even for its time!), Stevie Wonder and others. The entire complexion of some songs seems almost entirely reconstituted - in a good way. House music (from DJs like Cassy, Maya Jane Coles, Four Tet, etc.) absolutely sings too. I thought I’d audition the Katanas to see if maybe, just maybe, I was less of a basshead than first thought. They didn’t quite do it for me upon auditioning but I was so tempted to go with them to see if I’d grow to love them. But my musical tastes of course do need something with low end emphasis. Indeed trance has virtually no soundstage (hence the Shure SE846s are a good option for trance/progressive listeners as they have a very boxed in intimate periphery).
