Generally don't ask don't tell in my house regarding my purchases or hers. We keep mostly separate finances. I thought several purchases of mine went completely unnoticed but one day she walked over while I was tinkering and said, "I don't know how much any of these cost (points at every new item) but I'm not dumb" and left the room.
Have you ever deceived your wife-audio purchase
This could lead to a hysterical thread. How many audiophiles have come home with an expensive amp/preamp/and told their wife they bought it for practically nothing? Only to have paid 3-4K they had in their private stash? How many audiophiles have secretly installed a new "toy" in their audio system thinking their wife wouldn't notice. My old girlfriend thought anything beyond a boombox was excessive. Whenever I would upgrade my system,I would come up with some far fetched tale(lie) Would love to hear your story.......
