The TF has an insulated case. The T carries the negative rail voltage on the case.Bassterror said:@nina:
I mean AC.
@cpemma: I cant find any difference between T and TF in the sheet

Yes, I know. But does that affect the heat flux?The TF has an insulated case. The T carries the negative rail voltage on the case.
For a 4 ohm load you will need a larger than normal heatsink also. I'm speaking from experience. Chipamps love 8 ohm loads and hate 4 ohm loads
Right now I've got 8 ohm speakers at my computer. But I want them to be capable of driving 4 Ohm loads. I want to be flexible.
Assuming I torture them with 4Ohm.
- Will this affect the sound seriously?
- What will happen when they get too hot?
Can I hear them suffer before it's to late?

Sort of, indirectly. If you use the "T" version, you must isolate the heatsink from other circuit elements, OR use an insulating washer to isolate the chip from the sink. Your choice (there are several options) of insulating washer will directly affect the heat flux.
If you use the "TF" version, no added washer is needed. You should use heat transfer paste with either version.

- Will this affect the sound seriously? No.
- What will happen when they get too hot? Thermal Shutdown until temp goes down below shutdown threshhold.
- Can I hear them suffer before it's to late? No.

Not hear, but you can feel the heatsink getting really hot
