If you want the best sound quality, the airlens hands down. Years ago I went with Auralic over the Aurender because of sq and lightning DS is light years ahead of aurenders software.
The airlens only has 2 output interfaces and you want to use the i2s interface. If you notice, the airlens doesn’t include the flawed usb interface.
I use Roon with ps audio DS dac, and the airlens will make your dac sound better. Get the best I2S cable you can afford.
Using i2s, you won’t be fooled into buying all those usb tweaks/gimmicks which try to get the usb interface to sound better. It’s like putting lipstick on a pig
