I got the ARESII and compared to any other DAC I have heard so far in my main far-field system it is head and shoulders ahead in certain respects. I rewired my far-field rack so it can now be used for comparative purposes just like an audio reviewer. It performs instant A/B tests by volume matching with a switch and as I listen for hours at end it also serves for long term testing so that I don't get fooled by "drive-by" impressions. SPDIF/RCA and Balanced lines are now rigged up outboard of the stacks so I can swap in whatever to compare to whichever DAC is in position one. My new wiring setup provides two addition input positions to load up with DACS and race them all against each other. So far two of my my old time professional studio 20 bit and 24/96 DACs from way back when still are holding their own at those particular resolutions. But of course they aren't modern enough to do true high res 24/192. They were made by Symetrix---ones a Lucid 96/24 and the other a wonderful fat sounding 20 bit AD/DA setup from 20 years ago. Great analog output stages kept their SQ well above the el-cheapo DACS I bought lately just to test and fool with ---like Toppings little D50s and D10. BUT. Useful comparisons for sure. I also run a Bryston 24/192 and a Benchmark 24./192 setup. So there's a lot of Delta Sigma DACs of good solid reputation to run against the R2R Denafrips of the world. They are all Delta Sigma chip types up against the R2R of the ARES II. The Ares was so good I immediately ordered a Pontus II. Stay tuned as I intend to do a long term listening comparison and try to nail whatever improvement the Pontus provides over the little ARES II. It will have to be phenominal. Because so far the ARES II is shocking my world. Further words and descriptions will have to wait until I am more sure of my opinions on these DAC comparisons. So stay tuned---the Doctor is IN.
