What could these 2 transistors on a Infinity Reference 10001A?

[jfxwave]

The two markings below are T2X. I am unable to identify the other two, but I have encountered T2X alongside T2T.If anyone has information regarding this, I would appreciate assistance, as I cannot locate a schematic for the Infinity Reference 10001A.

If these are located in the power supply section, they look like the totem pole transistors that drive the fets.

They are probably MMBT4401 and 4403

I'd agree, The leading lower case t isn't part of the part number mark. It's likely a production location (Taiwan?)

Attached is an example from a different manufacturer. The prefix t means Malaysia.

Yes, I thought it was 2T.
Thanks for reinsuring me.
