RDAC or DAC IT?

Anyone compare these two DACs? Stereophile gives them both great reviews, though in the end they seem to lean ever so slightly toward the Pecahtree.

I'm coming from a MF V-DAC, which, while decent, doesn't offer as much detail as I'd like, and adds an electronic sounding shimmering to some piano music. My main components are a NAD 326bee and Monitor Audio BX2s. They provide a nice balance - the laid back NAD with the lively BX2s, and I'd like to maintain that with a nicer DAC.

Thanks.
