Thanks for the feedback! I was curious if anyone tried and as mentioned the earlier firmware releases didn't support 2GB cards. I'm already today using a bunch of 512MB, 1GB and 2GB cards for different genre of music and audio books. One of the reasons why I actually bought the BeoSound 2 in the first place; being able to quickly switch the content by replacing SD-cards.
But, I was curious if anyone tried out with >2GB cards - nothing else and nothing less. I'm more or less always using 320kb mp3 and/or lossless formats. So for example being able to use flac or ogg would be a great future feature.
