Lumin U1/U2 versus T3

Currently using a T3 and out of curiosity demo'd a PS Audio Direct Stream MK 1 DAC. The PSA dac definitely improved my system and my question is, will the U1 or U2 be a substantial or noticeable improvement over the T3. Not ruling out a PS Audio Airlens as a streamer either using I2S. Currently I'm using spdif out of T3 to DAC via BNC.

I meant to add is the U1 still relevant or recommended as I know it's a bit older.

U2 is good. U1 is still relevant. 
Worth experimenting with a good USB cable from Lumin to DAC. Good chance it might beat the coax interface.

Can't use USB due to T3 can only use spdif out.

@audphile1 USB is input for external hard drive.  Digital output is spdif.
