The outcome justified the approach «Cost and time no object“

Sooner or later there comes a time in the life of every audio engineer, when the question arises:

“How far can I push the limits in the quest for life like music reproduction?”



The outcome justified the approach «Cost and time no object“

Sooner or later there comes a time in the life of every audio engineer, when the question arises:

“How far can I push the limits in the quest for life like music reproduction?”

Based on our knowledge and expertise, combined with years of meticulous listening tests and comparisons, topology of amplifier represents one of the major design directions. Here we believe that Tube Push Pull Mono Power amplifiers combine the best of two worlds. The force of a state of the art Push Pull amplifier and the Triode magic of a reference Single-Ended Amplifier. With the Directly Heated Triode tubes like 211 or 242, a true tube power of up to 40 Watts per mono-block can be unleashed, which is sufficient to drive even the demanding speaker loads to the state of the bliss.

Needles to mention, outmost care has been given to the choice of best possible parts and materials in the MA100, ranging from the exceptional DHT tubes like WE 300b, new production TA 300b, 211, or the eternal 46 tube. For driver tubes we use exclusively Western Electric ones, while tube rectification is done by state of the art TA 274b.

We are extremely proud of the Power and Output  Transformers as the special attention has been provided in their development and production done by the biggest authorities in their respective fields.

All of the above was tested and scrutinized again and again, until we have been able to completely sort the wheat from the chaff which brought us to complete satisfaction with the achieved results.

By now we assume that you reached a similar point in thinking as we did, arising with the same question: “How far can we push the limits in the quest for life like music reproduction?“. We believe that we have the answer to this question personified in MA100 power amplifiers. The authenticity and authority with which the MA100 power amplifiers celebrate any kind of music gives us the tranquility that we were looking for.

Our Push Pull Mono Power Amplifier MA100 reflects the heart and soul of music. You owe to Yourself to hear them at least once.

Since my boyhood days I have dreamt of making the best sounding components because I could not find them on the market. With 25 years’ of expertise, I have managed to make my dreams come true. And so can you.

I live and work in Central Switzerland next to beautiful Lake Lucerne, surrounded by mountains. Empowered by my wonderful family, I work with a team of unique experts to make those audio dreams come true. I take a lot of time to develop and manufacture high efficiency coaxial speakers, tube amps and DACs. Deeply rooted in audio history, I am also fully aware of today’s manufacturing advantages and apply them whenever they will be useful. Please take your time to experience my components and I can promise you, it will only take moments before you realize that you are listening to something special, something musical: a gateway to the music. Let me introduce you to some secrets behind the making of these products.



We at Tobian Sound Systems believe that the beauty of our audio products lies in the hands of the makers. I may be the originator and driving force, but the products have more than one father.

My amplifiers for example benefit from the unique expertise of the man who is responsible for my transformers. His 50 years’ of experience from the heydays of tube amps until today, cannot be matched elsewhere. A while ago we had the chance to integrate another veteran transformer specialist into the team. This man started with Peerless in the 1960s and his hands know exactly what to do. Thus we are fortunate to be able to blend Swiss and German knowledge and precision with American engineering. This is not written in the books, it is written in the hands and hearts of the experts, because they live this trade and keep their secrets to themselves. However, in the end all is revealed in my products and the beautiful music they produce. They say the heart of a tube amp is in the output transformer. But what kind of output transformer?

Our wire is very slowly dragged and carefully isolated with natural resin and then baked. The next step is the alignment of the wire on the core. The core of the transformer is made of a special, grain oriented steel, that only one company in the world makes – in Switzerland. Each layer of oval-section wire is then hammered into one homogenous surface. It is along the outside of this augmented surface that the signal will travel. Each layer is then isolated with mu-metal shielding before the next layer goes on. After a transformer is finished, it is submerged in natural resin, and baked. Every step of the process, the materials, the execution, the duration of each phase, the precision that only comes from experience, turns these transformers into something you cannot just buy. You have to be dedicated to have them made like this. It’s as if they are dreamt into reality. Put your hand on one of those transformers while the amp is on – are you sure it’s really on? You cannot tell. Like driving a Bentley: only when you look at the dashboard do you realize how fast you are really going.
