Just my 2 cents: Almost every Sabre chip based Dac I’ve heard including ones with the 9038pro chips, sound extremely bright and are very forward in their presentations. I’m not saying they sound bad, but compared to my Berkeley Alpha 2 and Ayre QB-9DSD, they sound a bit harsh especially in the upper mids/lower treble. I reluctantly bought a LKS 004 and sold it on EBay 2 weeks after using it. The Oppo stuff , at least BD -105D, has the same fingerprint. For the money, the Ayre is one of the best USB Dacs I’ve heard. My only beef with it is it only has one Input and it’s USB. The Berkeley is the best I’ve heard under 5K for Redbook CD, HDCD and 24/192 streams. It will not decode DSD, hence the addition of the Ayre. I also found playing files out my Bryston BDP-2 are light years better than my MacBook Pro using Vox. I believe the Bryston uses a Linux based software. I think the delivery system is sometimes more important streaming files than the dac itself. As a side note, I had a chance to hear a Cocktail Audio X50 playing through Mytek Manhattan II dac. Absolutely stunning and I believe the Manhattan uses Sabre 9038 chips so there is hope for that chipset..
