what upsets me among other things with ayre is the codex and ax-5 twenty can both do 4x dsd but they have them locked to 2x...
latestyle, you may want to feed that with a good hub, filter and lps plus good xlr cables. that will bring it from very good to true reference class. if i did that(which i have) and i worked for stereophile, under those circumstances i would rate it a+. they have not rated it afaik but other publications rated it a, just stock.
i am thinking now to put in a 9038 pro. it is pin compatible i bet it does not make much difference though. the sound of a dac is really everything but the chip. in that regard ayre got it right..
