Other than technological advancements, DACs seem to be a flavor of the month type thing. I've read many reviews, including one of the Eastern Electric Minimax in which the reviewer says it's the best thing under $1500 and better than the Wyred4Sound DAC. Bam, next thing you know in the W4S's recent review from the same reviewer (Daryl) the Minimax gets blasted when compared to the W4S which is now mighty superior.
