My friends high end sony system with square speakers (yeah I’m old) kept poping the speaker coils out of their sockets at 70% power. His 600$ sony dvd player would not play burned DVDs. My Phillips amp would power my realistic home made speakers up to 100% and they could still take a lot more (200W RMS amp and 275W designed speakers) and my weird named 65$ DVD would even play DIVX movies on burned DVDs. Fuck Sony.
