I get my Stax headphones to sound their best (loosened up?) by playing at what would be painfully loud volumes for a minute or two before I put the phones on to listen. Seems to work well."
Of course, as fate would have it, there are no tone bursts, as you call them, on the disc under discussion.. Neither is the break-in track on the XLO Test CD composed of tone bursts, nor the Cardas.
