With my VR-4JR I just bi-amp and dispense with the umbilical as Albert suggested.
ILLusion Liquid Air Umbilical for Modwright units
Guys,
I can tell you this without hesitation if you haven't already done so, upgrade your stock umbilical cord to an Audio Magic Liquid air or even an Illusion Liquid Air which I have and you'll be blown AWAY!
The results are like changing a component, this cable produces spooky pin-point imaging, 3D layering within the soundstage, low level detail never heard revealed with no brightness, pitch black background, extremely musical and truly a chameleon.
This cable is truly a revelation and must be heard to believe and I can say without question that you will be amazed...
