Summary: I am using Bose 901 VI and research lot as my Powerful Vintage Yamaha CA-810 stop working. It was difficult to find Best stereo receiver/ Integrated Amp for less than $1000 for my Bose. I tried Yamaha R-S700 as it has very attractive specs but it sounded thin, annoying, narrow sound stage and low power. So I bought HK3490 and it is INDEED very High Quality receiver. HK3490 sounded clean, Very loud like Live Concert, 3D and long time enjoyable musical sound!
