Craig, I'm sure that you will be pleased with the result. My first suggestion was predicated on the possibility that you might be in a radio-rich environment. Since it seems that you are not, unshielded may be a better solution. If these work out, that is, no obvious radio frequency interference, you should never need to upgrade. |
terry9 A star ground is important if ground is used as a circuit element, such as a signal return. A shield attached at one end is not part of the circuit, and cannot form a ground loop, or hum.This is completely mistaken - a shield attached at only one end most certainly can either form a ground loop and contribute to hum and noise, or help alleviate hum and noise. That's exactly the purpose of using such a shielded cable, but of course it requires proper orientation of the shield to be effective. Remember that the term "ground loop" is really a bit of a misnomer; we can say a "ground loop" is formed whenever two or more grounds are at different potentials. Also, the term 'source tend' seems ambiguous to me - is it the turntable or the preamp?It's the preamplifier. What would be the purpose of running all the grounds through the pickup arm and cartridge? As noted, star grounding is unimportant in this case.Your connection scheme may work in your system, but I know for sure it wouldn't work in mine. I can't see any value in using an amplifier - as opposed to the preamplifier - as the common ground connection. |
