Monster Cable
Wire and cable should NOT be as expensive as they are.
Fancy shielding and other "features" do NOT make your speakers sound better. If you are delivering power at a power level of 5 Watts to maybe 100 Watts to your speakers, and the cable is not thousands of feet long, then just about any piece of wire would do the trick.
On the other hand, if your amplifier is built with some low-quality brand of audio amplifier chip, your speaker wires could just act like giant antennas to radiate the noise all over your home.
Harman used the D2Audio
"brick" for a while (maybe they still do). NAD is still trying to make the Zetex
design (or DDFA, or Class Z or Acoustar, or whatever brand name it is) work just like Theta was trying to do with Zetex for over a year until they sold the company just before CES2008. Several companies use ICE power
audio boards. These companies buy other people's boards or reference designs, drop them into their box, and sell the public on the idea that they are amplifier designers. I even heard one company at CES still talking about The Flying Mole. Maybe it didn't sound good, but at least The Flying Mole and IcePower sort of worked. It amazes me how reputable amplifier companies are willing to drop some cheap digital amplifier into their product. The Sonance Booth even had some amplifier brochures referring to "Class T" by Tripath. That had to be old considering the status of TriPath.
And, if you saw the Monster display at CES2008, you would know that Monster does not need any more of your money to stay in business.
Besides, over at the International Business Park area of CES, there is no shortage of Shenzhen Sue's ready to give you all the cable you need at the bargain basement price you need to afford the good stuff elsewhere in your system.
So, don't succumb to the "add on" impulse buy of additional cable that the dealer tells you is "needed." You are likely to find better stuff at Home Depot.
