I have the 1077, and it does exactly what it was designed to do, which is to be really small and really cool running.
if you are from htguide.com, you must have an impression that the 100wpc digital modules can brew your coffee and walk the dog, but this just isn't so (at least for me - people there say 99% of the people like how the 1077 "sounds", I must be in the 1% - lucky me) ... it does exactly what it's supposed to, if you want louder and more powerful, I suggest you look at the 1092 series instead.
