Only once did I have my thumb directly on the mute button again: Maximilan Merk was visiting to find out about the current status of the settings and had brought Peter Gabriel's album Up with him. The deepest electronic sounds can be heard on "Sky Blue” - ideally suited for testing, but otherwise rather nothing for me. The Thiele TA01 and the Etna mastered the enormous demands completely unimpressed and the Veloynes and Aeon Fines didn't show any distress: There was nothing boomy, the sounds came across very differentiated and clean. One could enjoy all the advantages that an almost unlimited low-frequency reproduction brings with it, without the sound seeming even slightly thickened. By the way, I didn't need to press the mute button here either. After so much electronic sound we deserved something special: Wolfgang Puschnig's "Peace" from the album Chants, not from the hard disk, but from tape. Quinton Records gave me a copy of the mix-down years ago, that is, the first two-channel version of the recording, free of any compression or final mastering interventions. I like to use the title to show what sonic potential lies in such seemingly antiquated technology as tape machines. I have never heard the piece sound as good as with the two Velodynes. A dream!

The question still remains how the sonic gain due to the two subwoofers is to be classified. For me, the differences between the reproduction with and without are clearer than, for example, the differences in sound between Lan switches such as the Telegärtner M12 Switch Gold and the SOtM sNH-10G i plus sCLK-OCX10 or the SOtM-Duo and the Ansuz Acoustics PowerSwitch D-TC Supreme. The price difference between the switches approaches in the first case the investment necessary for the purchase of a DD+ 10, in the second case it is greater than the sum to be paid for two Velodyne. Even if you put the costs of cables and other high-end accessories in relation to the possible sound improvements, there is a lot to be said for buying subwoofers, especially since the optimal solution can be achieved with two of them step by step. Do you have to think about it for a long time?

By the way, while writing this article I listened to the album Travel Guide by the three guitarists Ralph Towner, Wolfgang Muthspiel and Slava Grigoryan, and turned the Velodynes on and off every now and then. And even if guitar sounds don't romp in frequency ranges where the DD+ 10 are active, the ECM production was simply more fun with subwoofers.
