Not sure if the current Cambridge DAC's still use the wolfson 8740/41/42 series, but at one time they did...check the ASR reviews of the Cambrige DAC 100 and Dac Magic units...
Won't be a popular opinion here but I've often "subjectively" liked the sound of outboard Dac's or CD Players (i.e.- later versions of the Rega Planet), that use the wolfson devices...but again, the opinion won't be of much value on this forum...
Apologies in advance to all who have been offended by reading this opinion...
