I have the Pontus ll and I love it. The full sized Liav DAC is somewhere between the Aries ll and the Pontus ll. The uLiav is much closer in sound to the Aries ll in both sound and price. If you have the budget, I’d go for the Pontus 15. It’s using most of the parts from the Venus 12th and it’s a very nice improvement over the Pontus ll.
All the best.
