The quartet maintains an active collaboration with broadcasters such as SWR, HR, WDR, Catalunya Música, Radio France, Danmarks Radio, BR, NDR, SR, ORF, and Deutschlandfunk. The ensemble’s CD recordings for the label OehmsClassics reached top positions on the classical charts, were presented as the editor’s choice by various broadcasters, and were chosen multiple times for Lufthansa’s Album Selection. Its second CD, featuring the music of Joseph Haydn, received an ECHO Klassik award nomination in 2010. The acclaimed performance of Chausson’s Concerto for Violin, Piano, and String Quartet, Op. 21, with the delian::quartett, Liza Ferschtman, and Benjamin Moser, was included as a live recording in the anniversary edition of the Piano Festival Ruhr in 2018. The same year saw the release of the double CD “Cantai”, featuring Bach’s “The Art of Fugue” alongside Stefano Pierini’s work “Cantai un tempo…”, written for the delian::quartett. That recording received, among other honors, the maximum five stars from the Italian magazine ARCHI and a nomination for the OPUS KLASSIK 2019.

A major commitment of the delian::quartett is the expansion of the repertoire. It has given world premieres of works by living composers Alberto Colla, Per Arne Glorvigen, Gabriel Iranyi, Christian Jost, Stefano Pierini, and Uljas Pulkkis; most of these compositions are inscribed to it. In 2019, Aribert Reimann dedicated his last completed work — his adaptation of Schumann’s song cycle “Frauenliebe und Leben” (A Woman's Love and Life) — to the delian::quartett and soprano Claudia Barainsky, who premiered it together at the Berlin Philharmonie. In 2024, the legendary label ECM Records released the album “Im wachen Traume”, featuring, among other things, the world premiere recording of this work. Described as an “original recording of rare beauty” (nikonland.it), “Im wachen Traume” has been a classical music recommendation, must-listen, Choix Musical, or Sélection Disques for various European broadcasters and print media, and was included on the longlist for the German Record Critics’ Award (Deutscher Schallplattenpreis). In the Süddeutsche Zeitung, critic Wolfgang Schreiber named the album the most beautiful CD of the summer, and the magazine Fono Forum awarded it the coveted “Star of the Month”, with maximum ratings in every category.

With "Let's Get Classical!", the Delian format for young people and the young at heart, the ensemble also wins over concert newcomers to classical music. The delian::quartett has regularly performed and continues to perform alongside artists and ensembles including Gilles Apap, Fabio Bidini, Measha Brueggergosman, Gérard Caussé, the Deutsche Kammerakademie Neuss, Stella Doufexis, Andreas Frölich, Pavel Gililov, Bernd Glemser, Per Arne Glorvigen, Jens Harzer, the Henschel Quartet, Julia Hülsmann, Ralph Manno, Sergei Nakariakov, Ulrich Noethen, PiedraMudaLAB, Menahem Pressler, Dora Schwarzberg, Peter Shub, Peter Simonischek, Ulrich Tukur, Anatol Ugorski, and Angela Winkler. With the great actor Bruno Ganz, the Delians shared ten years of their artistic career until his death in 2019, in various acclaimed spoken-word reading projects.

Since 2017, the members of the delian::quartett have been united as Pirastro Artists in a partnership with the renowned string manufacturer. Adrian Pinzaru plays a violin by Giovanni Battista Rogeri, 1699, generously passed on by Christine Anderson; Andreas Moscho’s violin is the Giovanni Battista Rogeri “Christmas”, circa 1690. Lara Albesano’s viola by Alfonso Della Corte, 1884, is on permanent private loan.
