Re: Yamaha 591BL any good?
Hi Saurabh - welcome to HTF.
Usually there is only a slight difference between a unit and the "a" or +1 unit so I would imagine the 591 is not much different with the exception of fixing a problem or two.
My own observation is that the Yamaha electronics are great but they seem to save money on the speakers.
I like yamaha but I keep seeing more and more Onkyo HTIB's that seem to be pushing the envelope.
Just remember that as long as the unit is a fairly well respected brand, when properly setup they all do a great job for movies.
Good luck and let us know what you decide and what your impressions are when you un-pack and setup your unit. (we all love stories).
