Good to have you here.
I looked at your receiver list and they sound like solid options for a loq budget. But throw the notion of Bose right out the window. Bose is into the science of advertising and not the science of sound like they claim. They're stuff could be recommended if it were 100% cheaper but for what they ask, you can get alot more for your money. I suggest looking at Athena, Polk, Paradigm, PSB, Mirage, Energy, Mordaunt Short, Canton, Sinclair, etc. Lots of choices that are so much better than Bose.
Read some of the sticky or permananet posts on how to purchase speakers. I suggest taking some material, CDs and DVDs that you are very familair with along with a pad of paper and listen to as many speakers as you can. Right down what inpresses you about them abd what you don't like. Is the bass tight and fast or boomy and sloppy. Do the mids sound clear and life like or to male voices sound chesty and full of bass. DO the highs sound accurate and airy or accurate and grating? Do they image well? Do they throw out a big soundstage? Is teh ability to pick out instruments in the soundsateg important to you: if so can you hear the individual instruments relative to one another? These are some of the things to take notice. Let us know how you are progressing.
