There is this Douk Audio product with 3 different configurations of oscillators.

-3 standard oscilators
-3 temperature controlled oscilators
-2 femtosecond oscilators and 1 standard

There is also this:

-2 temperature controlled oscilators.

I am looking to get one to hopefully improve the quality of audio from my DAC (ENOG 2) -- yes it is a pretty basic DAC, but this would be for future proofing as well.

I am more inclined to go with the second one as I will probably never use i2s, but if the first one is significantly better, I could save a little more for it.

Basically I have no idea whether or not its good or needed. Currently getting TOSLINK from my built-in X79 motherboard.

X79 TOSLINK > ENOG2 > THX 789 > LCD 2F / DT 880 600ohm
(All Balanced)

This is nice one for I2S, but TCXO clocks are no-name. Clock upgrade is important when using I2S. Not sure how much it will help on S/PDIF. Crystek CCHD-957 is a known name, but not amoung the best.

Don't be fooled with Lusya. TXCO oscilators are only on the photo, not in description, price indicate a cheaper. This is a typical trick on Chineese online sites.

I was doing more research on Crystek CCHD-957. Apparently they are good, just old.

I was thinking that I don't need I2S now, and for 200 USD for the upgraded oscillators, it is better spent on a new DAC.
