I have a 10.5i, and although it says Nordost on the arm, there is no indication of Nordost wiring internally in the junction box. I personally believe all the junction boxes are wired the same with the exception of RCA or XLR termination. You can simply open up the junction box and look inside to see if indeed it is Nordost wired. I was about to do that, but figured aside from getting me disappointed, there was no point. You can also call Harry who will tell you the definitive answer. I suspect that the wires are so short in the box that it makes no sonic difference. If it did, Harry would have made a Nordost junction box.
What VPI junction box do I have?
I have the JMW9 Sig tonearm with Nordost wiring but not sure I have the Valhalla junction box. All it say's is "JMW Memorial Tonearm". Is there a way to distinguish between the regular and the Valhalla? Also, does it make sense to get Nordost phono interconnects? I have the VPI IC's now.
