I am always suspect when someone uses the phrase "kills it" when describing sound differences between two comparable pieces of equipment. I personally think transport to DAC synergy is very important to obtaining good sound. I think the Linux based Antipodes-gear is fantastic using the Ipeng interface. Initially I had the Antipodes DS Reference which is fantastic heard the DX version and immediately upgraded my unit. I like the flac file format Antipodes uses, it also helped me with my little Astell & Kern AK 120 as I used the flac files backed up from my Antipodes and loaded them to the 120.
I am sure the Bricasti is a better sounding DAC based on the reviews, but I'm going to stick with the PS DS because of the upgrade path and their ability to close the gap on the competition very quickly. I also put some Synergistic ECTs and a big red fuse, switched out a Verastarr Grand Illusion copper cable and inserted their silver Grand Illusion Signature, which for me took the sound up a whole mother level. I'm sure if I inserted the Bricasti it would be mind blowing, for me right now the PSA DS and Antipodes DX is a phenominal combination. I heard Steve's Empirical DAC at a show and the system sounded phenominal to say the least, I am willing to bet it will give all the Dacs in this thread a run for their money
