I'm using MHDT Havana as well, my friend who owns PS Audio digital linkIII came to my house one day, after hearing my Havana, he said PS Audio produces incerdible details, which he said sometimes it was too much, sometimes he got tired of all those details(but gives u the upgrade bug). Secondly he said, PS Audio brings power to bass in all kind of music, if you are into bass.
His reaction on Havana was,,the sound is so real, so true to the timbre, u don't have to "imagine" a drum kit, just close your eyes then u "believe" the drum kit is in front of you kind of realness. Havana is also a lot more analouge sounding than PS Audio, which is more musical sounding to me and my friend agreed.
I haven't heard Paradisea either but i heard Havana's much better in details.
Here's my take on these 2 techonologies: I used to listen to CDP that has upsampling DAC built in, and PS Audio would be a top notch upsampling dac u could ever get, the way upsampling deals with details is separating all the sound. It becomes so easy to focus on one instrument.
Havana uses non-oversampling technology, which gives more coherent sound. Some said it doesn't have the detail, being a musician myself i can feel more soul with havana, for me that's the sort of "detail" i like, call me old school if u like but i think young kids are missing out the ambient of the room that was recorded in, the movement of the performers. I'm sure 10k upsampling CDP produces that no problem, but just imagine what 10k non-oversampling can do compare to that.
