I originally preferred the Gold Lion KT77. Now, I feel they have too much bass and sometimes depending on my mood, a tad too bright. The 7581A has less amount of bass, so you might want to look into the GL KT77.How's the bass on them? Im looking for a warm power tube with strong bass for Susvara. At the moment settled for RCA Black Plate 12AU7 into Gold Lion KT88 ... need some socket savers
