help me remove noise from my vinyl setup

hi all,

i have a low-output vinyl setup, and the noise hovers around -60 dB. i would like it to be lower. can you let me know where the problem might lie and suggest solutions?

i have a Technics SL-1200 (M3D) that i got from KAB, with most of the upgrades... fluid damped tonearm, Cardas tonearm wires, strobe light disabled, and the external power supply/conditioner. i have the low-output Grado Sonata1 (statement series) and Cardas headshell wires. i have Grado's prestige interconnect cables between the turntable and a Grado PH-1 phono stage. finally, i have a Blue Jeans MSA-1 cable between the PH-1 and an ASUS Xonar DX sound card in my computer.

here's a recording of the noise:

there is also a slight popping/crackling noise, can you hear it?

i borrowed a Furman PL-8 Series II power conditioner from a friend, and tried plugging the PH-1 into that. i also tried plugging the turntable power supply into it. ...it didn't help any.

many thanks.

I use mu-metal sheeting to protect my MC step up amp from hum/noise induced from external EM fields emitted from amplifiers or other nearby transformers.

I roll the mu metal sheeting into a oval tube large enough to insert my step up device into and it works like a charm. Hum/noise otherwise audible is gone.

The mu metal sheet needed cost around $35 in my case.
