Sampling Problem

Hi, i have a problem when i sample from my technics to my MPC 3000, when i sample a rich sound with lot of instruments, i don't hear it, but for example when i want to sample drums, isolated sounds or when i'm listening to the empty parts between tracks one a vinyl, i hear a loud snoring sound and another one higher.
For this reason i can't sample drums because there will be a noise after it.
I use a Technics 1200 SL with a new Arkiv needle, plugged with a monster cable to a Vestax PM5 pro 2.
Do you know where this noise comes from?
Thanks

I'm having this problem also. Technics 1200 mkII, Radial J33 preamp. Buzzing in anything I sample from the turntable. I've also tested sampling through my Rane 56 mixer with a Technics 1210 mkV.. same thing. Sampling from my iPod I was unable to reproduce the issue (but cmon now, I dont want to take samples from my iPod with all this vinyl on the shelf behind me!).

Anyways no solution as yet.. but thought I'd chime in. Seems to be a grounding issue at this stage.. and having just had the power supply in my MPC 3000 replaced it would appear that this may be where the blame lies.

is the turntable properly grounded?
