Removing Unused Preamp Connections

**jimdgoulding** · 03-02-2008, 01:47

I run my leads direct into my tape inputs (one at a time). I read somewhere that doing this bypasses all the other stuff on my line stage. I don't know if this is universal. Perhaps VG and Mike can tell us more. What I hear doing this is less artifice, more organic, smooth sound.

Another solution is to use optical digital connections, when possible, thats how I got read of the hummm comming from the satellite antenna...

Hi Antonio,

Just ignore it. The matter is in hand.

Doing so, in my experience, improves sound quality and gives a more natural, detailed, and 'focused' sound. Quite often, a lot of the stuff that's plugged into your preamp isn't used regularly so why not maximise the performance of the components that are? The improvement is subtle but in my opinion definitely worthwhile.

This is another 'tweak' mentioned in some of Russ Andrews 'bumf' somewhere I think.

I cant tell any difference on my amp, but then the inputs are relay switched and all inputs except the one in use are 'shorted' to ground anyway.

mike,
it may make a diffrence because each piece of equipment connected to the pre-amp will have a diffrent earth potential, so even if the inputs not being used are grounded, the signal return of each component is still in the circuit.
thats only relivent mind you if all the signal returns rely on mains earth.
in the soul series they dont!
