When I do make a direct comparison between boards, (I always prefer to compare with live sounds) I always make sure the sound system is the same and/or use my own headphones.
In addition I also have the T2 & T3 Demo DVDs and the difference stands out clearly. (The compressed sound does not apply to the SA2 voices, which are excellent)
If you read some of the posts of the T3 on YPKO you will also find this mentioned.
