Decided to upgrade from the 2M Bronze and pleased with the results for sure. Listened first to Joni Mitchell Ladies of the Canyon and then my favourite LP if all The Song Remains The Same. The 2M black digs more detail out of the groove and separates the vocals and other instrumentation to a level I haven't had before. It's not a radical change from the 2M Bronze, but certainly worthwhile. On the live Zep album, concentrating on Bonham's drumming, I found myself appreciating his fills while loving Page's solos in a different part of the soundstage. I am running mostly vintage British kit, Linn speakers, Onix amps, with a Thorens/SME deck. Upgrading the source, i.e. the point closest to the groove is definitely more worthwhile than spending fortunes in the amp/speaker department.
