Vladimir Shushurin Danku Šuvaru:

he M1.1 behaves the same, into 8 ohms I have voltage of V2 with 2.5 A of idling current. Into 4 ohms (when load switch is changed) I have V2 volts minus V1 volts and idling current of 3.5 A. That’s the same! That means 100W of pure class A into 8 ohms and 100W of pure class A into 4 ohms. The amplifier does not double its power into 4 ohms. In this case the doubling of power occurs only at 2 ohms. The harmonic structure is not the same because all amplifiers that double their power when the load is halved do not operate the way they should.

So by using the load switch your amplifiers stay in class A longer into 4 ohms?

My amplifiers are designed to operate that way. I can show you, for example, that we have 100W of pure class A into 8 ohms. If you were to change the load to 4 ohms and leave the load switch set at 8 ohms, you would get 200W, just like with conventional high-end amplifier designs. However, this way, you would only get 50W in class A. Also if you changed the load to 2 ohms you would get 400W but only 12.5W in class A. The amplifier doubles the power but I don’t need that. My load switch is equivalent to output transformers in tube amplifiers. Have you read Ken Kessler’s review of M1.1 (Hi-Fi News and Records Review) where he states that he felt as if someone were sitting inside the amplifier and doing something. You can hear the difference immediately if you use 8 ohm speakers and flip the load switch to 4 ohms. The effect can be heard immediately because you have changed the Q-point.

Sviđa mi se taj Vladimir Shushurin. Evo što nađoh u tekstu, između ostalog:

'...solid state topology is limited when it comes to correct reproduction of sound... Tube technology, for example, if we consider push-pull designs, can overcome these limitations. If this is, for example, 50% or 60% (of the theoretical limit), the best one can do with solid state, the difference between the best solid state “push-pull” amplifiers, even in class A and without negative feedback, and the best tube “push-pull” amplifiers, is at most 10-15%. They have no limitations... Of course, with single-ended topologies incorporating tube output and triodes.'

Je, a kad ga je itervjuer pitao što s faking izlaznim trafoom, on reče da o tomu nema smisla diskutirati jer je to jednako kao da diskutira o tomu treba li mu vlastita ruka ili mu ne treba. Dakle, istaknimo što nam ide naruku (onu koja treba), a prešutimo ono drugo. Usput, valja također čitati što o pojačalima imade reći Dan D'Agostino koji nikad nije napravio lampaša, a i neće.

Lik jer napisao puno dobrih stvari vezano uz pojačala:

"Which features of your design are most important?

You have to understand that all parameters -- THD, slew rate, rise time, whatever else -- are only a part of a more complex system of parameters. If the amplifier is designed properly, then these parameters can be used to truly describe the performance of the amplifier."

i

"Are these measurement characteristics your idea of ideal amplifier behavior?

This is the result of my theories. If a system satisfies these requirements, namely that characteristic distortion is always the same, and that the shape of distortion is always the same at all frequencies, then it automatically implies that it is not necessary to solve a system of differential equations with seven unknowns, as outlined in my theory of audio design. When we simplify it this way, then parameters like THD, inter-modular distortion, frequency response, slew rate, etc. will mean a lot and acquire a specific definition.

On the other hand, when you see this silliness, like 0.001% or 1% distortion specs for some amplifiers, it means absolutely nothing. These parameters, like THD or whatever else, are meaningless all by themselves because they have no connection with reality. You know, all these parameters, all these types of measurements, come from the beginning of the audio era when designers knew nothing about negative feedback. They used direct-heated triodes, very linear tubes. In those early days, designers did their jobs the way they were supposed to. Without understanding they made good devices.

Not all these parameters are independent. For example, the standard way of measuring dynamic range is the ratio of maximum and minimum power, limited by noise. This is wrong. It’s not even close. That would mean that if we increase power we get more dynamic range. For example, this 18W single-ended amplifier, ML2, has the largest dynamic range that one can imagine. It has nothing to do with power. There exists a more complex measurement and it is not an independent parameter because dynamic range is a function of at least five variables."


ili i općepoznate stvari koje neki djelovi naše audiofilske scene izbjegavaju kao vrag tamjana:

"Do you think all these power filtration devices are necessary?

It seems that a whole industry has emerged around this issue. It is necessary. The power grid is dirty and it needs to be cleaned up, but that is a so-called necessary evil. All my amplifiers and pre-amplifiers are equipped with quality filtering networks. Industrial quality. Yes, I do it, but not because I like it, but because I think it is necessary. In big cities the power grid is so dirty, so many bad things…"


a činjenica su i realnost bez obzira koliko novaca smo ili nismo spremni uložiti u tako nešto (bilo kroz kupnju pojačala koja već posjeduju filtracije kakva su njegova ili kupovinom zasebnih filtracija kada uređaji koje koristimo ne posjeduju ovako sofisticirani ulazno zaštitni sklop.)
