Certainly, Peter. As I outlined, there was digititis in my system that was real, as I discovered upon switching from a 20 year old Wadia 12 DAC to the Berkeley Alpha 2 DAC (that unit isn't entirely free from digital artifacts either, as I recently discovered in comparison with the Yggdrasil DAC). Yet the real digititis still accounted for a rather minor portion of all the perceived 'digititis', which mostly came from issues that were not related to the digital itself.
Seems to me you are confusing "digititis" with other distortion and room induced artifacts.
