Which part reduces surface noise most?


Hi all -

I have been lucky enough to hear a few turntable setups that put surface noise/cracks and pops "on another plane", which makes focusing on the music so much easier. These tables have included:

Well-Tempered w/ unk Audio Technica Cart and modified Dyna PAS 3 preamp
Linn LP12 with various Benz Micro cartridges and Audio Research phono stage
Kuzma Stabi with Cardas Heart (Modded Benz Ruby) cart /BAT phono stage

However, I've yet to recreate this phenomenon at my home. Granted, I've never spent the kind of money required to buy the 'tables listed above, but I'm wondering where the next upgrade step is for me.

I currently have a Techncis 1210 with Cardas wiring and the KAB fluid damper with an Ortofon 2m Blue cart playing through a NAD 304 integrated. The sound is pretty good, but the crackles and pops still really bother me.

In your experience, is it a function of the the stylus profile, the phono stage, low-output vs high-output, mc vs mm, or any combination of the aforementioned that will help me in my quest to separate the noise from the music?

Any input will be most appreciated, thanks!

Joelv,

As Raul said, every part of the reproduction chain can help reduce surface noise and remove it to some other plane (perfect description - I know exactly what you mean by that). Some of the most significant factors include:

Record cleaning - Disc Doctor fluids leave much to be desired IME. You'll get a notable reduction in hard clicks and pops with an enzyme based system like AIVS or Walker Prelude. Highly recommend you make that switch.

Stylus profile (already noted by Tvad) - in addition to running quieter, a micro-ridge stylus massively reduces inner groove distortion and makes a big improvement in the clarity of high frequencies.

Arm/cart matching - as noted by Raul.

TT quality - particularly the platter. In this area there's nothing better IME than a well damped, high mass platter.

Phono stage quality - no one has mentioned this yet but it's the BIGGEST FACTOR OF ALL. The componentry in most entry level phono stages is easily driven into ringing, overload and distortion by transients with very fast rise times and large peak amplitudes (e.g., from the stylus whacking a chunk of dirt in the groove). Top class phono stages have higher quality components and more stable power supplies, which lets them reproduce the size and shape of the dirt accurately, with less of the exaggeration that makes such noises so noticeable.

It's a long, difficult and (unfortunately) sometimes expensive path to reach the kind of "distancing" of noise that you mentioned. And it's pretty much guaranteed that without a good quality phono stage you will never achieve that.

Restock,

We use all four AIVS solutions, but as you know we're fanatics. We did try using just three (Enzyme + Super Cleaner OR Archivist + Ultra Pure Water), but repeated experiments demonstrated that all four solutions provided an audible benefit (to our ears/in our system/blahblah).

We actually do two rinses with UPW, making five steps in all. Using our somewhat slow (but very effective) Loricraft, it takes about 15 minutes/side to clean our records. We surely wish there was a faster way, but we haven't found one that compares.

Paul also thinks there's a scientific argument. The enzymes are essential, nothing quiets a record or removes mold release chemistry better. The alchohol in the Super Cleaner denatures the enzymes. The surfactant in the Archivist helps displace the alchohol. The UPW removes the surfactants... FWIW.

Aren't you glad you asked?!
