pontus has a slightly warmer tone than ares and also better clarity - it is the warmest of the dena dacs in midrange and midbass that i have tried (ares, term, pontus - i have not yet tried a venus) the terminator provides more deep bass and a forward but still refined treble, the ares has the least clean treble, a problematic sibilance no matter what mode and what filter is used, and a somewhat ill-defined bass compared to the better ones - thus i have kept the pontus which is my favorite among the dena dacs
one other thing to note is that the pontus dacs received running changes over cy 2020 and 2021 before they officially marketed it as a version ii unit in spring 2021 ... thus many that are not marked as pontus ii on the faceplate have the ’version 2’ upgrades -- wima caps in power supply, new dsp board, tripod feet denote the pontus 2 essentials
