I wanted to get the xlr to trs cable but i dont know if there will be a sound quality difference between the xlr to trs and the trs. I assume this is a dumb question but i want to make sure.
Assuming that the same type of cable is used with either configuration, there will be no sound quality difference. The plug type makes no difference to the fact that there are essentially three electrical connections that need to be made.
XLR and TRS are two different things.
XLR is a "balanced" audio cable, which means that it sends the signal in such a way that the noise picked up while traveling over the cable can be canceled out by comparing two different signals on the cable.
TRS, on the other hand, is used for a slightly wider array of things. It can be used for unbalanced stereo audio (where the induced noise can't be removed). It can be used for unbalanced inserts, where audio is sent out of a board and then returned in on the same connection, or it can be used for balanced audio with a different form factor.
The advantage in XLR is that it is a locking connector which does not require pins touching the wrong contacts as they are being plugged in, which makes it less likely to be pulled out while in use and also is safer, signal wise, in some use cases. The advantage in TRS is that it is a versatile cable that is used commonly for a wider variety of applications and can also act as a TS cable.
The difference in quality between TRS and XLR will depend on application. If you are forcing an unbalanced signal in to a balanced input, there will absolutely be quality loss. If you are forcing an impedance mismatch with a difference in line level then you will also have severe quality implications. If you are moving between different forms of balanced signals, it shouldn't matter significantly. If you are using a board that uses send/return over XLR, then going to a TRS instead won't have a major impact.
The form of the connector only matters when it is important that the tip not be sent to the sleeve or ring connectors or that it matter that the ring not be sent to the sleeve. As long as that doesn't matter, the connector itself has no real impact and would vary based on the quality of the connector more than the form.
What does matter is if you are changing the type of signal in a way that reduces quality or in a way that needs further adjustment that you are not doing (for example using a direct box or a pad).
