You're in the wrong thread - and probably the wrong forum - for a discussion like that. My understanding is that purrin's rankings are entirely subjective - initially, he did confer with others before he started trying to rank each of the DAC but by the time he got to the vintage R2R designs I believe it was a case of 'this is the best, forget the rest' : he has since climbed down from that lofty stance slightly but most of the recommendations now are along the lines of 'if you cant afford Yggy or you're not willing to wait, these are your options'. I know I'm putting words in someone else's mouth, but the posts are there for those who feel I'm being liberal with the facts.
I havent ventured into Sound Science for a very long time - its more 'Mad Science' in many of the threads - but that's where you may find more pertinent discussions of the topics you seem to be focussed on.

Thanks. That's really all that I wanted to know (that this thread is entirely subjective and down to opinion). Again, I am not denigrating peoples' opinions, I was merely looking for clarification as to the assertions that were made.
Many Thanks,
