I thought about my previous answer, so last night I got out the 580's and listened with a pod in the rack. Everything I'd said was confirmed.
I ran "Gypsy Queen' (part of Santana's Abraxas BMW) and it gave me tingles , really. Then next up was the live version of "Inna a godda da vita". It's 2 minutes longer than the studio version and the drum solo in the middle has 2 drummers, real impact. The 580's handled everything w/o problems and the bass was impressive when it was called for.
starting to think that I could get those hd-6xx's and pass my 580 to an appreciative son ?
yesterday I grabbed more cans , but I had not seen before. "Frequency Fan Club" , total isolation phones with volume control. They are made for racetrack communication, but sound pretty good on music too.
Oh yeah: those white comfortable PSB's a few posts back: the plastic headband broke in the middle , design flaw as many online had the same problem, customer service said "too bad". Then one ear stopped working. NO more PSB for me.
y'all would like the opening JBL reference on this review. See 2nd pic.
