Hm, remembering the history of VDMSOUND and DOSBOX I'd say full emulation wins in the long run...

The "sound stuttering" of SBEMU/VSBHDA is (most likely) caused by incomplete ISA DMA controller emulation - the index/count registers of the DMA channel are updated "occasionally" only (on sound hardware interrupt, which is usually each 2-3 ms; enough for games, but may be a problem for "hard core" SB applications like demos ).
