Audacity vs GLAME (Score 1)

I'm a die hard gtk user, so I am attracted to GLAME (http://glame.sourceforge.net/index.var). Can anyone compare the two? I'd rather not use a app that is also built for Windows as I fear it's linux integrety is compromised. Also eventually I am interested in SACD production. Does Audacity support 24/96 x 6 channels and 24/192 x 2 channels natively. Is there a linux app that can write to DSD? Thanx, Bearcat
