Best Way for my TT to reach my Pre-Amp!?

So just exploring I extended the TT phono cables to connect to the preamp using phono input selector. It introduced an intense hum only present on the phono input.

Is this due to the fact that my rca extension cables are not grounded like the TT phono cables? Now remember that I have a Rega and the grounding is not done through your typical separate grounding wire.

Craigert,

Keep in mind that a typical 1 meter set of RCA interconnects will add roughly 100pf on their own...  +/- 15pf.  Some designs/manufacturers start out way higher than that.


Since you say you make your own cables... I will obstain from any recommendations.

I agree with finding a phono preamp with switchable settings... but would also recommend one that has settings for zero capacitance.  

Either that... or one that you can pull the lid and swap the capacitors and resistors manually.  Some even allow a person to swap out op-amps.

Be careful you don't fall in the rabbit hole at this point. ;)

To those recommending Blue Jeans cable for TT's...

They are a decent cable... but for the next step up, for not much more money I would recommend trying the Analysis Plus Oval One.

To my ears it was a definite upgrade.

Assuming the turntable cable is hard wired and not a plug-in, buy a decent "audiophile," short (.5m orr 1m) cable and some gold-plated joiners and try them.  You will either hear a diminishment or not.  Don't assume the worse.  If you are using a MM, you may.  If you are using an MC cartridge, you probably will not.

I used my own cables to extend the TT cable as well as purchased RCA cables. They both resulted in noise and hum in the phono stage of my Marantz.
