I just wanted to add my kudos to Headfonia for doing God's work in pointing folks to great and affordable audio. After spending significant time and coin on upgrading my Crack (see my posts) I was still frustrated with the tonal range and fidelity. Putting her aside for (far too many) many months, I happened upon Headfonia's recommendation of the Topping D20 DAC and made the $129 plunge +39 for a decent Elpac converter. Long story short, this DAC (via TOSLink from my PC) is the SHIT and the Crack is a now totally different animal - everything I was looking for in spades. Thanks for the heads up Headfonia - you rock.
