Rule no.1 - never discuss hifi with the wife. Be creative if push comes to shove. How much are those speakers. Quote the price each
How much is that amplifier you just bought. Deduct any funds you could potentially get for your old gear.
Brucey bonus. Try and slide it in unnoticed. I nearly got away with a sub under a table until the hoover made an appearance. It was banished for all of two weeks while I was incredibly helpful around the house.
My next event is adding a power amp, which will join the BFD behind the av rack, covered in a bin bag to hide the lights.
Nipping out to cut-off the courier before my wife even realises there is a delivery is an art form. Whispering it's a present helps keep voices down.
Will there ever be pink hifi? I fear not and until then we have to outsmart them. It all adds to the thrill of the chase!
