A visit to CoolTech

29.12.2022 // Dirk Sommer

Back home, he then pursued the idea further, went into business for himself and founded CoolTech in 2009. Initially, he teamed with a company in Spain, which treated components for him there. However, as the volume of items increased, transport became too expensive, so Wolfgang Lausecker installed his own cryogenic treatment facility in the idyllic Stanzach in the Lech Valley. In addition to cutting tools for metalworking whose service life is extended by around 60 percent thanks to the cryogenic process the engineer - who plays baritone saxophone in a big band in his spare time - also exposes music instruments to extreme cold. By the way, Wolfgang Lausecker has already performed with multi-instrumentalist, composer and bandleader Matthias Schriefl, whom the Süddeutsche Zeitung counts among the best jazz trumpeters in the world and of whose virtuosity, joy of playing and esprit you can convince yourself with a few clicks thanks to our free download  But back to the sub-zero temperatures: Their effect on brass instruments did not just convinced Wolfgang Lausecker. The sound changes caused by the cold, which were consistently perceived as positive, also led to successful experiments with electric guitars, cables and (tube) amplifiers. Even wind instruments made of wood are said to benefit from the treatment.

On the one hand, CoolTech works with renowned German automotive and tool manufacturers as well as the Fraunhofer Institute and technical universities, on the other hand with musicians. On the one hand, whilst there are scientifically verifiable advantages of cryo-treatment, there is also the issue of sonic-aesthetic taste. And the audio scene is also moving in this direction. After the positive experience with the instrument cables, it was obvious to cool down loudspeaker, NF and signal cables as well. The changes in tubes, pickups and SSD hard disks caused by the cold were also rated positively all around by the clients. The treatment is intended to perfect the crystal lattice structure in cables as far as possible and thus improve conductivity - an effect that cannot be detected with a home multimeter, which requires more sophisticated measuring equipment.

In my opinion, the fact that the sound changes in pickups or musical instruments cannot be explained explicitly in physical terms does not speak against the cryogenic process. In the now more than 25 years of professional involvement with hi-fi and high-end, I have become accustomed to trying out products whose mode of operation cannot be conclusively explained. If it sounds better, the reasoning behind it is secondary. That's why I would also like to find out - not for the first time - how cryo-treatment affects records, because during the pressing process - the rather warm vinyl is shaped between the pressing plungers, whereupon they are then cooled - a lot of material stresses are likely to occur. And cryogenic treatment is all about optimizing material structures and reducing stresses. More on this later.


  • Interview mit Jean-Pascal Panchard – Teil 1

    Als ich im Juli darTZeel in der Nähe von Genf besuchte, machte ich auch einen Abstecher nach Vetroz, wo Jean-Pascal Panchards Lautsprecher-Manufaktur Stenheim beheimatet ist. Vor mehr als sieben Jahren hatte mich seine Alumine Five in meinem Hörraum begeistert. Für Anfang nächsten Jahres ist die ausgiebige Beschäftigung mit der Five SX geplant. Natürlich war ich neugierig darauf zu sehen, wie groß die Fertigungstiefe bei Stenheim ist: Zwar werden die Chassis zugekauft, aber von den Herstellern…

  • Statements in High Fidelity | Polish Edition 2024

    Wenn es um die Statements in High Fidelity geht, teilen Wojciech Pacuła und ich uns die Arbeit. Es hat sich eingespielt, wer die Ankündigung in seiner Sprache und dann die englische Übersetzung formuliert, wer die Einladung für die Gewinner schreibt und wer die Preise in Auftrag gibt. Den Bericht über die Feier verfasst traditionell mein Kollege: „Diesmal gingen die Preise an Jark Waszczyszyn für seinen CD-Player Ancient Audio Lektor Joy und an MSB Technology, in…

  • Statements in High Fidelity | Polish Edition 2024

    Das Magazin meines Kollegen Wojciech Pacuła, highfidelity.pl, und hifistatement.net zeichnen zu den Messen in München und in Warschau schon traditionell jeweils eine Komponente aus, die uns im vorausgehenden Halbjahr begeisterte. Im Mai hätten wir fast versäumt, die Preisträger vor der High End zu nennen, diesmal sind wir lieber etwas früher dran. Bei der Bekanntgabe der Gewinner für die Deutsche Ausgabe der Awards konnten Sie an dieser Stelle lesen: „Wojciech Pacuła kann es einfach nicht lassen.…

  • Interview with Monsieur Delétraz aka darTZeel – part 2

    A week ago, the focus here was on the professional career of the darTZeel founder and the circuitry features of his patented output stage. This week, we will discuss the company's employees, upcoming new devices, the special darTZeel 50-Ohm connection and Hervé Delétraz's musical preferences. Dirk Sommer: Since when have you been able to make a living from your hi-fi company? Hervé Delétraz: Only very recently! From about 2010, it took quite a long time…

  • Interview with Monsieur Delétraz aka darTZeel – part 1

    Even before the High End, I had planned to review darTZeel's NHB-18S and NHB-108 pre/end amplifier combination. In the showroom, I asked company founder Hervé Delétraz about the technical details of his creations. He suggested that we talk about it in detail at the company headquarters and in his private listening room near Geneva. In the first half of July, the time had come: we visited darTZeel in Plan-les-Ouates. The company is based there in…

  • Erlkönig: Wilson Benesch Tessellate Ti-S

    Der deutsche Wilson-Benesch-Vertrieb hatte erfreulicherweise ein Einsehen mit dem Autor, der – wenn es um hochkarätige Komponenten geht – trotz über 30 Jahren in der Branche hin und wieder immer noch zu leichter Ungeduld neigt: Krey Baumgartl hat den britischen Hersteller dazu gebracht, ihm respektive mir schon einmal eine Vorab-Version des Tonabnehmers zugänglich zu machen, obwohl die Serienmodelle noch einen letzten Feinschliff erhalten. Auch wenn eines davon Ende September in Gröbenzell eintreffen soll, braucht es…
