I owned the TaDac and the PreDac, and the Havana was in another league from both. It had a much deeper and wider soundstage, and much greater bass extension. I had almost the identical set up to what I currently have, and you can look at my system.
I think it helps to know what someone has in their system when they comment on gear to know how it will match with yours.
