1. Tie you wife's neck with a rope, using a Reef knot. No other knots should be used. Only a Reef knot (I think it might be called a Square knot in the USA). Just make sure you do not make a Granny knot by mistake! Dont' tighten too hard, you may damage you wife. You will immediatly notice a vast improvement to the sound (expecially microdetails), due to the exceptional lowering of the noise floor.
2. Place your wife's credit cards under the feet of any heavy furniture, and make sure she cannot remove them. Be careful to place them in a diagonal pattern (never parallel to he furniture edges) and facing down, so that they cannot be readily identified. Listen to some music for a short time, then remove the credit cards and see if you can listen to the same music with the same pleasure - without the control on your wife spending habits.
3. Place one bottle of Absolut Vodka in a plain plastic bag and place this bag in the domestic deep freezer for one hour. Pour yourself a glass of vodka which has been through the freezing process first and then see if you can listen to music while drinking the other (unfrozen) vodka with the same pleasure. If you have success with freezing vodka, then try putting tequila or a bottle of dry gin through the freezing process also.
