The End Millennium, kaj pravite mojstri, je to v redu amp?

The Principle Schematic shows just how simple and ingenious this amplifier is designed. No feedback loops (100% non-feedback), no capacitors or IC's in the signal path. The frequency response stretch from DC to 500.000 Hz ( +0-3dB ), so any music signal from the deepest bass to the highest air, will flow freely through The End Millenium, to reach Your ears.

The Short Circuit protection does not affect the signal. It only monitors the currect consumed by the speakers. In case of an overload, the signal is shut down for a few seconds. Then The End tries to get back on line, but if there is still a short, it just goes off for another few seconds. If the short remains, the amplifier will wait for days, until load conditions are acceptable. Then it will play as if nothing happened! This is a very effective overload protection system, that we copied from our line of professional PA amplifiers.

Thanks to the new amplifier construction, which in several ways is ground-breaking Technology, we can offer you a kit-form amplifier that sets the limits for easy-flowing musicality and still with high grade audio precision.
This is features You would normally have to pay up to 10 times higher prices for, compared to what The End Millennium cost, partly because You assemble it Yourself, saving labor cost.
100% non-feedback = 100% musicality!
The warm - almost triode like - sound stage is owing to the absence of feedback loops in the amplifier's signal path. This principle of operation is called non-feedback, and is also used in some very expensive American Amplifier brands.
In a normal Amplifier the signal is sent into a high gain (typ. 100.000), high distorsion signal amplifier. A circuit monitors what comes out of the amplifier, and compares it with the input signal. If there is a difference, a negative correction signal is sent through the amp, to eliminate the error. The problem with this approach is that - speaking in simplified terms - that it takes some microseconds for the signal to pass through the amplifier, so the comparison is made between the fresh input signal, and a few microsecond old output signal. The signal could very well have changed in this period, making it impossible for the amplifier to track the signal 100% correct. In the same manner it takes the correction signal a few microseconds to reach the output of the amplifier, where the error is encountered, so actually the amplifier is comparing a signal that occurred some microseconds earlier, against a fresh input signal, and corrects it yet a few microseconds later. It is obvious that this is bound to give problems, when more complex signal are to be amplified, to give a demanding result quality.

In simpler words You can say, that an error can not be corrected before it occurs, and then it is in fact - too late! That is why we do not use feedback loops in our amplifiers!

Using sinewave analysis of the amps performance is a thankful task, since a sinewave - theoretically - contains the least possible amount of slewrate per Volt signal amplitude.
Music is very much more complex and hard to reproduce.
