IMHO, this isn't a bad play for D&M. Snell has not had a strong place in the upper end market for some time now. The presense of Snell was more strongly felt in the late 80's and throughout the 90's.
As for Escient; it's difficult to compete in a market with an increasing amount of cost conscious people beginning to utilize similar configurations with a video game consule, Blu-ray player, or home theater PC. The integration of an Escient system may be more seamless, but only a dwindling handful of consumers are interested or able to afford these levels of integration systems.
