  1. I posed the same question about signal ground isolation. I was told to tie the board grounds to the chassis ground

    using 1K ohm resistors. My KGSSHV is a single box build. No noise at all be it high or low volume, music playing or not.

    Thanks for the response livewire. Just to clarify this means that you did not connect the signal ground?

  2. So I'm getting close to the point of turning this thing on but I have some confusion about my grounding scheme. I am doing a two box on board heat sink build with the amp boards in one chassis and the ps in the other. Obviously in the ps chassis I have ac mains earth ground connected to chassis. I then have an umbilical running between the two chassis carrying both power supply ground and chassis ground, and signal ground also enters the amp chassis. What is the best way to tie these grounds together for safety and avoiding hum? I was thinking I would tie the amp chassis ground to the power supply chassis ground (and thus earth ground) and then connect power supply ground to chassis ground through a resistor inside the amplifier chassis. Does this sound like a safe scheme, and also is it then appropriate to keep signal ground isolated from chassis?

  3. It's the age old issue with every consumer product. If you want to be taken seriously then you have to have a price to match. No way in hell the HE Audio Jade cost anywhere near 1500$ to make but since it was setup against the SR-007 then that was the price range it had to be in. Also one of the reasons why the Koss ESP950 is never considered as one of the greats. Far too cheap at 650$ with an amp...

    Well said.
