"[14] Bruckner Insiders described it as "one of the bests sounds and interpretations",[15] and continued, Ken Ward writes in The Bruckner Journal of Schaller's aims in embarking on his completion: The fugue of the final movement is particularly central to Schaller's completion - the heightened contrapuntal tension concentrated into this fugue is used in the finale as a lead to the climax to the thematic material at the start of the symphony, transposed to the major key, and as a polythematic review of all movements as in the Eighth Symphony.

The Bayerischer Rundfunk (Studio Franken) produced the recording, the CD was released in 2021 by Profil Edition Günter Hänssler.

The original chamber polyphony of the five solo string players is retained in his strategy of arrangement, but at the same time much symphonic material is incorporated.

It's a Classical-Romantic arrangement with doubled woodwinds, four horns, two trumpets, three trombones and timpani to preserve the structures of the original composition and at the same time reinforce the symphonic content.
