Vinyl “Pops & Clicks” eliminators


I’m betting a polarizing topic, but I ask the question as a truly curious audiophile who has just not honestly had the opportunity to do any real research on this category of products....so, am not asking as either a proponent nor opponent of this technology.   So, a few obvious items: (1) it’s best to work with clean, unblemished LP’s (for multiple reasons) and (2) obviously a product designed to “remove” an audible defect is also going to affect the audible spectrum; but in what ways, exactly, both desirable and undesirable do these devices affect the music?

I’m talking specifically about devices like the Sweetvinyl Sugarcube SC-1, but I’ve literally done zero research so far on how many devices like this even exist.   The “Sweetvinyl” box comes to mind only because I see their ad in TAS mag, but I don’t know if there are other companies with similar products.   
Question is....we all have LPs in our collection that we acquired and for whatever reason were not kept “clean” and have scratches resulting in audible pops/clicks.   Are these devices — essentially selective filters — selective enough to do their job on imperfect records without destroying the surrounding harmonics?    Or do we just discard & reacquire any scratched records we own?   Or is this a “better” solution?

I’m gonna guess that literally 10% maximum of the Agon’ers who reply here have ever owned/heard these products used, so maybe let’s all just mention whether our opinion, our response, is based on real-life observations, or just theoretical replies.    Both have value, but for different reasons.

Best,

 Besides a much more musically satisfying sound, the Luxman's greater dynamic headroom tends to minimize surface noise compared to what I had before.  I expected excellent music but the surface noise reduction is an unexpected benefit from a design with a much more robust power supply.
^^This. I'm very used to not getting ticks and pops in my system. Its a simple fact that inadequate headroom in a phono preamp design can result in excess ticks and pops which aren't actually on the LP.
I should add that, for my own listening pleasure, I'll take the crackle with the additional transparency over suppression/processing.
There are a couple of ways to reduce or eliminate pops and tics.  The first way is to clean the records as best possible.  The second is to not play the part of the groove that has the pops and tics.  (Yes, Ricky.  There's some splainin' to do.)

The first way, cleaning, is well known and fairly easy to do.  Since the OP has a good record cleaning machine, that's not particularly relevant in this thread. 

The second way to reduce noise is more subtle and at least partially relies on a clean groove.  It has to do with stylus size and profile.  I cite the following as an example. 

I was using an AT OC9/II for years.  when one wore out, I replaced it with another identical cartridge, standard OC9/II stylus type.  I pretty much knew where most every pop and tic was on all my favorite records. 

I had an old Lyra Clavis Da Capo rebuilt by Soundsmith last year.  The rebuilt uses a Boron cantilever with a very small line contact stylus that rode deeper in the groove.  When it arrived from Soundsmith, it got mounted on an identical JMW-12 tonearm on a VPI Aries Extended (Original) table, the same as the OC9's.  The pops and tics almost completely disappeared.  The part of the groove where the new stylus contacted the vinyl had not (to my knowledge) every been touched by a stylus before.  There remained some deep groove damage that remained audible, but the groove silence was quite nice.  

The very small stylus takes a lot of the guesswork and concern away from buying used records.  Most used records have never had a stylus contact the grooves where the very small Soundsmith stylus rides.  I imagine there are some other cartridges with very small stylus.  It might be worth looking into rather than spending $2,000 and putting another piece of electronics in the sensitive phono chain.  

Just thought I'd share.  YMMV.


@bpoletti, that Aries 1 table is a good one (I have the non-extended version myself), and the Delrin top layer of it's platter may be partly responsible for the reduction in noise (unless that's the same table the old cartridge was on). Delrin is a good vinyl/platter interface material, providing some damping of LP's.

So Jim, next time you upgrade your table, look at models incorporating platters (or mats) designed to damp the resonance inherent in LP's. Damping the vinyl lowers the audibility of tics and pops.

Clean, static free records need absolutely no help in this regard. The only remaining problem is background noise like rumble that this unit will not correct. I would never spend this kind of money and tolerate any level of degradation for the rare bad scratch or pop. I also never clean my records. Contrary to popular mythology records come from the manufacturer perfectly clean. If played with a conductive sweep arm (carbon bristles NOT camel's hair!!) and a dust cover the records never get dirty and dust is never ground into the surface as any incidental dust is cleared out of the way of the stylus by the sweep arm as well as discharging the record so it never builds a static charge and therefore does not collect dust. 
If you buy used records then a record cleaning device is mandatory. I do not because every one I have ever played was unacceptably damaged. 
Even after cleaning. Once a dirty record is played it is done for. Thousands of PSI pressure literally melts the dust right into the vinyl surface and there is no system that can repair the damage.
