Absolutely! Doug Sax was the genius behind Sheffield Labs and it was his brother that designed the tube preamplifier that Doug used. Doug even built his own crossover for his Tannoys. They would have used Doug’s Tannoys back in those days. Doug Sax only switched to Active ATC in later years, long after his reputation was already well established.
Doug didn’t just have golden ears - I think we all can hear the genius of what Doug did. I believe the genius is connecting what you hear to a positive action to enhance sound quality. We can all recognize the superior quality of Doug’s work, however, only a genius like Doug could take something and know how to tweak it and make it sound as good as it possibly could. In the case of the D2D, Doug would set up everything for optimal sound and it worked so well.
My favourite is the sizzle on Blues Stay Away from me.
With your phenomenal setup it is quite possible you hear it just in the way Doug intended!
