The combo of Einstein NK60, 60W OTL monoblocks, Einstein The Tube preamp, Electric CDP7T Mk.II CD player, Adept Response power conditioning, A Cappella High Violin Mk.III horn speakers and cabling mated mellow, warm, nurturing sound with a lovely, sweet presentation. Playing the Ebony Wind Band’s take on the music of Silvestre Revueltas, the sound was especially beautiful and airy. Although not the greatest in the slam department, this system was not afraid of open, high extension. It also presented the midrange in correct proportion, which is no mean feat.
