A new amplifier came out that blew the 80- to 100-watt amps out of the water: The Phase Linear amp was a whopping 700 watts. A fellow we knew wanted the best so he bought not one but two. He even put in a dedicated 220-volt line to power this monster. Rumor was when he powered it on, lights in the city dimmed.
The night he debuted his prize, the guests gathered around. He proudly turned the many knobs, switches and VU meters to listen to the sound. Cranking the amps past 70 percent, a slight sound omitted as the tweeters appeared to glow orange. Suddenly, there was a buzzing, crackling sound, followed by a thud. The tweeter centers fell forward onto the carpet. His wife yelled, “Get those off my carpet!â€
No one stepped forward to remove the molten-hot metal that, by then, had sunk deep into the thick shag and padding, stopping short of the hardwood floor.
On the bright side, there were now two near-perfect circulars to set cocktails, which had never been possible before in deep shag.
