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.
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!
