Is it the cable or the cartridge or????

I just installed a Helikon into my Aries/JWM 10.5 set-up. I am using an ARC PH3se phono....there is plenty of gain but I've noticed a hum when I lift the arm off the record before muting (I know...must not do)......could it be the arm cable???? The VPI 10.5 uses RCA to RCA so I am using a Nordus Blue Heaven cable. Any suggestions or recomendation??? Thanks all!

You should be using a shielded cable from the turntable to phono preamp. The signal level from the cartridge is very low so the gain of the preamp is very high. Any noise picked up by the cable will be easily heard. The blue heaven has no shielding so it easily picks up noise.

What about the ground. You should check the ground and use separate wire to connect between the ground binding posts from tonearm(tonearm box) to phono.

Try the suggestions above but also realize that some cartridges hum with the VPI setups - Grado even makes a special line for the VPI's to prevent hum. I have an Aries and there were just some cartridges I needed to avoid - I am not familiar with the Helikon. You may want to call someone at the Elusive Disc for more input on this. What were you using before?
