Continue to hold your tongue. Do your own thing. Leave Dad alone to be happy in his sonic ignorance and light wallet.

I had to laugh at your story. After I bought my first pair of real speakers, a pair of Thiel CS 2.2's, I set them up in the living room (my wife even made "speaker condoms" for them when not in use so the cats would not use them for scratching posts. At a Christmas get together at our house a guest looked at them and said, boy those speakers sound real nice and look so unusual, are they Bose? I can remember saying no, but these were a close second, I said that I just could not afford (to listen... ) to the Bose stuff.
