Wig the pontus 2 my wife has and Iris ddc , my audio buddy 2 towns over has the pontus 12th the 15th on all their gear is now a generation better with these new engineers ,when Alvin left he took one of Denafrips engineers ,for the harmony which is a good dac , the pontus has non oversampling,and over sampling
which is good it gives you solid choices this new dac much better resolution ,then the 12th anniversary which was a bit better, this 15 model is a big jump up with the Iris 12 ddc added,now
best inner detail I have heard under $3k instruments have much more depth and dimension ,a drum head you can hear more of the interplay and Macro details
buying a reclocker is s no brainer it cleans the signal before it goes into the dac ,the Hermes better still but $1300. for $550: for the Newer Iris 12 it is clearly better then my wife’s gen 2 model. I2S is built into the newer Iris 12 .Wireworld Hdmi uses the same pin out as PS audio does . Just look inside on these 15 series dacs vs the previous 12 th. Pretty apparent , my unit still needs breakin ,but my friends has 400 hours ,I bought a older terminator 2 from my brother that is a solid dac , the new one in another league yet to hear it though Very good technologies in digital are progressing rapidly.
