I found this cab
http://forum.ppcgeeks.com/showthread.php?t=41385 I just installed the TouchProAudio cab. When you open it it gives the option of full boost or light boost I tried both and I couldn't tell the difference between the two So I put the full boost on my Touch Pro It is louder but not so loud that it seem to affect the speaker on the phone. I didn't try the Audiopara. Hopefully this will help you out.
