DAKIOM to the rescue






I'd like to add a plug for an intersting product. It is made by a company called Dakiom that makes an odd little box that parralels you speaker wires out their output. This thing claims to stop fluctuations in the negative feedback used in most amplifier designs. The cost is around $100, and they make most cheap amplifiers much more listenable and musical. So if you have inexpensive equipment, give these a shot. They have a money back guarantee and if they don't work... send 'em back. They will even pay shipping both ways. Negative feedback is used to make amplifiers more efficent and to test better when reviewed by Consumer Reports. Old tube amplifiers offen show greater amounts of distortion, but sound much more musical. One of the best amplifiers I have ever heard used NO negative feedback. So there is something to this. Negative feedback was actually developed by Harold Black for the amplification of telephone signals. The technique requires that part of the signal from the amplifier is fed back and compared with the input signal. Theroretically, distortions caused by the amplifier are corrected and eliminated. Therefore, the amplifier can be made to appear without distortion despite fluctuations in the power supply and other electronic components. So, our amplifiers aren't designed for beautiful music, they are designed to test well and look good when you read a spec sheet. Too bad, I want beautiful music. So why not just buy an amp without negative feedback??? The start at $2000 and go up. Way up. And that is just an amplifier, you will need a preamp as well. Oh, and there are no negative feedback home theater receivers. So just buy the Dakioms, and see if they work for you. New equipment always sounds better after it breaks in. So let them play a day or or two while you are at work and then evalaute the difference.
