Göbel High End Lacorde Statement USB, Ethernet and Digital XLR

05.01.2017 // Dirk Sommer

The splendid speaker and interconnect cables from Göbel Audio I really couldn’t resist. To be on the safe side I therefore listened only briefly to the power cables, but exchanged them before I got used to it. However, the most recent digital cables I cannot deprive from you – and really don’t want to – despite this being a quite dangerous endeavour.

The good thing – or the bad thing, depending on how you see it – is that Oliver Göbel's facilities and my listening room are not very far away from each other. When the system in his demo room undergoes an interesting sonic modification, or when a particularly enthralling test object or a new acquisition enter my premises, both of us quickly can drop by each other’s place. And sometimes, also one or the other component changes place into the colleague’s listening room in order to show its capabilities in the respective chain. Yet some time ago it happened that I got an AES/EBU cable, which is still waiting for a review as I didn’t have a compelling application for this type of digital connection so far. During a comparison test of preamps and NAS systems in Oliver Göbel’s company, nearby located in the Bavarian town Alling, he mentioned that he was currently working on USB and Ethernet cables. And, I couldn’t await listening to these wires in my system – as well as testing them, of course. Eventually, I was able to persuade the designer to hand in a prototype of each of the cables for a first impression, which namely could be different from the serial versions in terms of termination and probably also outer diameter, but not in their sonic characteristics.

The prototypes’ connectors still lacked the characteristic aluminum sleeve with the milled company logo on them, using a simple shrink tube here instead. Also, the USB cable’s parallel running power and data wires are projected to be a good bit thinner in the final version, but – as aforementioned – this is of a purely cosmetic nature. Even if the outer jackets of the Ethernet, USB and AES/EBU cables look almost exactly the same as those of the interconnect cables, they host a different number of conductors in different geometric layouts – in so far as, for example, four shielded conductor pairs are required for the Ethernet connection and 110 Ohms are mandatory as impedance for an AES/EBU application. It is therefore not the case that Oliver Göbel simply transferred the knowledge gained during the development of the speaker and interconnect cables to the new cables, even though some fundamental insights were useful for the new designs. As it happens with most of the cable manufacturers, there is not much more you get to know about the buildup. Oliver Göbel only pointed out that the high price of his cables results mainly from the handcraft required in the production, and is not caused by the processing of exotic materials. The price debate which is so popular with cables, I rather leave open to you and me here: One simply has to know for himself if the few remaining percent on the way to more canorousness will be worth it. Above a certain (high) level, significant improvements are only viable by superimposing extremely increased efforts – whether this is with components or with cables.

  • Intona High Speed USB-Isolator

    Ein Schallplattenspieler bot und bietet seinem Besitzer unzählige Möglichkeiten, auf den Klang Einfluss zu nehmen. Bei CDs sah es da schon schlechter aus. Das wohl größte Betätigungsfeld findet der aktive Audiophile jedoch beim Thema Computer-Hifi. Da blickt man schon gerne mal über den Tellerrand – und stößt zum Beispiel auf Intonas USB-Isolator. Eines der größten Probleme, wenn Computer – ein Streamer ist auch nichts anderes – und Audio-Komponenten zusammentreffen, sind die hochfrequenten Störungen durch die…
  • Göbel Lacorde Statement Ethernet oder wohin mit dem Router

    Oliver Göbels Digitalkabel sind nun in der Serienversion erhältlich – werden aber nicht in Längen oberhalb von drei Metern angeboten. Könnte es da sinnvoll sein, den Router näher bei der Anlage aufzustellen? Aber wie wirkt sich das WLAN-Signal auf den Klang der dann in der Nähe stehenden Audio-Komponenten aus? Ein Experiment. Dass Oliver Göbels Lacorde Statement Ethernet dem Klang meiner digitalen Wiedergabekette ausgesprochen förderlich ist, habe ich ja schon im Bericht über die Prototypen geschrieben…
  • JCAT Reference USB Cable

    Anfang dieses Jahres hatte ich im Rahmen meiner Beschäftigung mit dem Player JPLAY auch das JCAT USB Kabel ausprobiert und war von dessen klanglichen Qualitäten sehr angetan. Das JCAT Reference USB Kabel soll in klanglicher Hinsicht noch einmal eine deutliche Verbesserung bringen. Nachdem ein Testexemplar dieses Kabels zum damaligen Zeitpunkt nicht verfügbar war, kamen Marcin Ostapowicz, einer der beiden Köpfe von JPLAY und JCAT, und ich überein, einen Test dieses Kabels zu einem späteren Zeitpunkt…
