[LAU] hifi stereo supporting linux filesystem?

Hi all, it's the first time I write in this mailing list and I hope I'm not OT. I'm looking for a hifi stereo system with USB support. I mean: I want to be able to plug an external USB hard disk, browse the folders and choose the files I want to listen to. I've found some products (by Cambridge Audio) that support all the formats I use, i.e. Ogg and Flac. But it seems that the only supported filesystem is FAT32. I wonder if you know some product which support some more advanced filesystem. Hopefully ext2/3/4, but even NTFS would be maybe better than FAT32. FAT32 is slow and doesn't support some characters in the file name. I know I'll have some problems copying my huge collection of files in a FAT32 filesystem. Any hint is appreciated. Thanks! Federico
