Interesting comment about the MP3 decoding on the SB units. I assume the ARM-based Touch/Radio should have better decoding algorithm than the earlier SB3/Boom/Transporter IP3k-based devices? Indeed. Not all MP3 encoders were created equal so one can't say modern LAME is equal to Fraunhoffer (for example) at the same bitrate...
