My system: Software: JRiver Media Center Source: Asus Essence ST SPDIF out Correction: MiniDSP DDRC-22D Dirac Live DAC/Pre: Antelope Zodiac+ & Teddy Pardo LPSU Speakers: Adam S3a + Adam Sub-P Room: W16.5’x L14’x H9.5’ Treatments: 4 GIK244 panels at first reflections. Position: On desk 3.5’ equilateral triangle TLDR Summary: The X Sabre Pro is a realistically priced option for certain tastes/systems and has exceptional build quality for a sub $2000 DAC. It sounds clean, uncompressed, modern-normal, has a silent background, is less harmonically rich than some, presents a wide sound stage but is shallow in depth, it will also tear apart a recording warts & all and as a result can make some tracks sound less natural/pleasing. It’s the least offensive Sabre DAC I have ever heard. XSP Settings: Dither On Jitter Off Filter 3 AES Input +0.0 fixed output Test Tracks: Comparison done between the X Sabre and Antelope Zodiac+ a 1792a chip pro-sumer DAC from the early 2010s which retailed for around $2500. Differences between DACs to my ear are always quite subtle things, so grain of salt on all this, my system, my ears, my preferences, etc. I won't bother translating my thoughts on every single track. Steely Dan-Aja-Deacon Blues: Wider stage width on the XSP, hard pan cut up effects on this track more forward/obvious, sounds a bit flat/boring, leaner mids upper mid bass through the XSP. Cymbal air is however is wonderfully nuanced. Radiohead-In Rainbows-Weird Fishes/Arpeggi: On XSP bass slam and "meatiness" significantly less, staging wrap well out past the speaker edges on certain effects. Extremely clean sounding on this track. Personal preference would prefer a bit more thick/richness. Tool-AEnima-Eulogy: Here the recording plays to the XSP strengths, the cleaner/leaner presentation allows for the track to come through with less "mud' so to speak. The decay and reverb on the intro are really beautiful on the XSP. Other Thoughts: First I want to thank Matrix & SBAF for the opportunity to give their very cool DAC a listen. Also I think it might help as a visual to show how some other DAC reference compares to me in general gross sonic warm to bright for the community, "Bifrost Multibit...Lampizator G4...GumbyA1....DAC1541(Red Filter)..Zodiac...XSP..YggyA1.....Benchmark DAC2" Last words? A beautifully built normal sounding Sabre DAC for clean freaks who like their Gin neat but of good quality.
