I have a Kula with built-in Tambaqui. It is fantastic, no doubt. Its transparency, clarity, and spaciousness stand out while also sounding relaxed, effortless, and in no way hot up top. I prefer my dCS Paganini + Network Bridge combo, though. To me it sounds a little more natural in tone and presentation. At this level there are no losers, though. It's all a matter of preference and I find it silly when people proclaim this or that piece to be THE best in the world. I also have a Boulder 866 with built-in DAC and recently had a Lumin X1. All very high performing and enjoyable DACs. But for me, it's dCS.
