I have may kte. I use i2s connection with PLL off. No delay. Sounds awesome. But, There's a trick to May that LTA nor other dacs in this price range cannot match. Use May NOS mode and feed up-sampled DSD 128 or higher (I use Hqplayer), it sounds as good as any high end DAC. That's where May excels and not sure if others are taking full advantage of that.
