Ironically the Buckeye amp(s) that Stereophile reviewed had defective Purifi modules, hence the poor test results.
There will be an updated review in July of 2025.
I felt bad for Dylan who has worked so hard to get some respect (other than ASR).
That said, I prefer class D with linear power supplies; ATI and Axiom to name a couple of mfg's that use that approach.
