Wife trouble

I think if it were me I would be trying to figure out if she bailed  cuz the gear or because of some other reason. If it's truly the hi-fi,  then I would ditch the gear in furtherence of a relationship with a loved one. Get the relationship on stronger ground and regroup and try and slowly reintroduce hi-fi at a later time. On the other hand if she was going to leave irregardless of the hi-fi, and the hi-fi was just the scape goat, then I wouldn't get rid of it. Because it ultimately won't change anything. Only you can make that determination. 
My uncle brought me into this crazy addiction, as he puts it's a disease. But a manageable one. He always said, "We aren't into drugs, we don't gamble, we don't chase women, we aren't into drinking and raising hell, but the one little vice is we are into hi-fi". It keeps life interesting...

Whenever I purchase any audio equipment over a grand, I give my wife an equivalent amount to do as she want. Keeps me very careful about what I buy and she now loves my audio passion.

Firstonetallguy -- I was touched by your post, both as a man who also adores his wife and is genuinely interested/invested in her well being and happiness, and as an individual with acquired  hearing loss ( after the purchase of a 30k 2 channel system).  Thankfully my wife puts up with my hifi addiction ( she half-jokingly refers to her "stereo crackhead" husband when explaining our living room design motif to first time visitors of our home),  and my significant hearing loss only involves one ear. 
I would add that, in my pursuit of great sound and the audio equipment that would deliver it, I was mindful of not only the WAF factor, but my own aesthetic sensibilities.   As Mr Schroeder pointed out above, a wife doesn't want a garage for a living room -- and I don't either.  So I went with a Focal 2 way stand mount rather than Maggie's 

The love of my life for some 43 years has been most understanding of my Audio Indulgences. Over the years, she has worked with me patiently to arrange living spaces to accommodate the best sound and maintain livable aesthetics. We now have a 15 ft. wall of drapes on a wall with no windows, behind the Maggies, but she made them look good and it serves the need for dampening some unwanted reflections, so - win/win. We have the video room set up just off the kitchen which works well for her and the audio room is in the living room in another section of the house, which works well for me and we don't mind sharing each others space. A little patience and working together can make things work.
