I had an ES 350 loaner vehicle for three days with the standard premium sound system. I thought it was pretty good at normal volume levels. All it needs to really enhance it for anyone who wants to listen at high volume levels and have better quality sound is the addition of of quality subwoofer as some have already done. I think it is actually a pretty good system.
(but, the ML is far superior.)
