To be perfectly clear, I posted both paragraphs with a single click of the mouse, and my post was never edited (as confirmed by the obvious lack of an "edit" time stamp on my post - no. 6056). Blame it on an implausible forum glitch if you like, but your accusation of after the fact edits on my part is both inappropriate and demonstrably false. In any event, I've said my piece now, and I'm happy to accept ac500's sound advice to move back on topic. Bygones and all that.
As it happens, I'm listening to the MFSL Ella & Louis box set on my HD650's right now - what a pleasure! The 650's certainly do justice to most genres, but to my ears, there is something really special about how they playback well recorded jazz. The incredibly natural timbre of live instruments and voices is just awesome.
