This unit is a Beast when paired with the right speaker/subwoofer combination. And, yes, also with proper placement and setup parameters. I have had this A3000 for a couple of months and have been quite impressed by its sonic qualities: Hooked up to a Paradigm PW2200 Sub.... and using a 7.1 setup... using PSB Image 6T's, Image 9c, and 4 Image 10s.
I have listened to several receivers and this is the one that came close to what I wanted. The Sony STR-DA 5ES and the STR-DA7ES were two that I had really enjoyed for its tonal quality in both movies and music. However, Sony Receivers have taken a trashing lately and, thus, I decided to move away from the new ones. I came from a long line of Receivers like McIntosh, Luxman, Bryson, Denon, Marantz, Pioneer, Philips, Grundig, Sony.... etc. Currently in my fifties, I owned and have been around numerous sound systems and auditioned and also attended live concerts and shows etc. I do know what I want in a Home Theater/Music room setup. Of course this is a totally personal thing. We all know by now that Sound/ Picture is an individual thing, each has their own likings etc.
Arguments will continue and comments will be made as questions get answered, however, none of us may be right or wrong. Anyway, making a proper decision can come from proper suggestions and advice.
My take: If you are currently looking for a fairly good Receiver without the advertized problems that other top brands are currently experiencing (as mentioned in this, as well as other forums), then go for an AVENTAGE by Yahama. Since I have had mine... it never overheated or shut down etc. I had an extremely short video drop out a few times with playing a DVD. However, this was solved by changing the HDMI cable.
I have given this unit a thorough workout with both movies and music. My HT Room is 30ftx15ft and 10ft high, and this A3000 is quite a Monster and very suitable, or should I say, capable in it. I am not disappointed with it in any way, except... and this is not a negative, but it would have been nice to have the volume overlay on screen switchable on/off as an option.
Well, fellow HT and Music lovers, sorry for the long review. Just remember, "Sound is a personal thing". Good luck with your choice, and hope you enjoy it to the fullest.
