@mijostyn My numero uno recommendation is to clean the stylus after every LP side is played. I’ve been doing that for 45 years with a brush, liquid every 25-50 plays and using a Magic Eraser occasionally now for 15 years. My Benz Ruby3 lasted nearly 2500 hours and tracked beautifully, but it lost all it’s dynamics at the end (on a modified SME IV arm).
I have 28,500 LPs. Most were purchased used. Most are very quiet. A scratch does sound. Pops and clicks sound (sometimes subtle, sometimes obtrusive). Bad vinyl in my system and several friends systems has various levels of low noise but the music overwhelms the background noise that it is generally irrelevant (guests frequently comment is it a CD we are listening to).
I used to have considerable record noise prior to obtaining a high end analog system. Four friends own Dynavector cartridges and I went back to that company’s 20X2L which is a perfect match for my Zesto Allesso SUT as well as directly into my preamp’s 100 ohm input for MC.
I first recommend a less expensive alternative (not cheap) which I’ve used for 31 years, the VPI RCM 16.5 (upgraded from a 16). Now using Disc Doctor fluid, multi-step wash and dry (3 minimum). or
I purchased a Kirmuss Ultrasonic (but do not change the water daily. I over the unit and unless there is debris from dirty old LPs, I continue using it for about 25 LPs). I noticed that it also cleans out gunk in damaged grooves, exposing noisy damaged surfaces as well. It typically enhances the sonics, even when there is increased noise. However, the noise level of bad vinyl does not intrude on the music. Example-I have several jazz Metro (MGM cheap label) LPs which are pressed on crappy vinyl with noisy surfaces. In my system, the music is so present that the noise is confined to a low level, unobtrusive shhhh. You’ll known it’s not digital or a CD but it will sound great (just heard The Mitchells Red, Whitey, And Blue* With Guest Artist, Andre Previn* – Get Those Elephants Out’a Here).
So, my most important recommendation is keep your stylus spotlessly clean.
Next, clean your records without creating any residue which contaminates your stylus.
Then, choose what you can afford to clean them.
