Out of curiosity, which interface are you using to hook up your digital files to your Havana? I ask, because I found the USB as implemented on both the Havana, and Paradisea+ to be entirely lackluster. The SPDIF on both were easily heard improvements to my ears.
That said, I actually found the PS Audio DLIII to be a more resolving DAC and at less cost than the Havana. It is available with various degrees of modifications from Cullen Circuits, but the one I directly compared was bone stock. There are lots of DACs in that price bracket that make for stiff competition. For the same money as a Havana, or just a bit more, if you can find a used Audio GD Reference 8 or 7 I'd jump on that. I have the 8 in my office system and it's a really great DAC, with remarkable resolution with no stridency throughout, and sounding entirely natural with all of the program material I listen to. I am particularly sensitive to the front end in that system because I listen to it frequently on headphones which are not very forgiving to various digital nasties.
