I can say without reservation the difference in the digital mods (before and after) that Wayne does makes a pretty dramatic difference. Couple the mods with a good power supply and a good DAC and you'll never look at your CD player the same way again. In fact, I'm within a few days of putting my AH! Njoe Tjoeb and my Arcam 8se on the market (any takers?). They literally have been gathering dust for well over 6 months. Me, I'll never own another CD player. The modded SB is THE way to go.
