I have upgraded my CarPC to v 1.7RC3, from the good old v 1.4
So this is the first time I have the ability make some sound quality comparisons between the old and the new. Keep in mind I have used 1.4 for about 1 year in my car, and I know very well how it sounds with my equipment. I know sound percpetion is subjective, but I have a very good reference point.
I notice that sound quality is definitely different in RC3. I am using exact same settings as before: Flat EQ, No normalization, and volume levels are set to same (main and pre).
I would say that in 1.4 the bass response was better. It was richer, chest punding base where it mattered. I can't get that anymore with RC3, and I don't know why. Fiddling with the EQ helped a little for some albums, but then made other albums worse.
David, has the Sound processing changed since 1.4? In what way?

check your install. Something might have changed on the audio side of things. Amplifiers, speakers, connections, grounds, power, speaker wire, etc.
Hey Justin (and David)... I think I agree with you. I've been having issues with CF's embedded XM support, so I just switched back to AIMEE. There is a DEFINITE difference in how AIMEE sounds versus CF - like you say, the bass response is tighter outside of CF. There are obviously a couple of variables there, but given that the source is constant, I have to point and say it's the difference between the internal & external XM apps.
installs change over time, wires come loose and move. Connections rust and corrode.
Doesn't matter if it's worked great for 10 years. Things happen, ESPECIALLY in a car environment.
