Audio Quality - Bluetooth vs. 3.5mm cable

[dwmackay]

Greetings,

My car stereo has the ability to stream BT music as well as input from the headset output of the TP2. Is there any technical difference in the quality of the sound between the 2 alternatives?

I have tried to do a comparision of the 2 options, but it takes me too much fiddling to change inputs that I cannot do quick back to back tests.

Thanks for any advice.
