Results from Beta Testers of New Formulas

Yes, Paul, I'd be happy to pay you for the larger quantity, too, and thanks for offering. Dave

Hi Paul,
I too would like a larger quantity and would be more than happy to reimburse you for any/all costs. Thus far I am very impressed with the promise your product holds. Thanks again.

Ok, so here is what we got going on tonight:
I pulled out 4 LP's, all of whom have known "issues" with noise. All of them have been in my collection since I was a teen/college student. They are:
Beethoven "String Quartet, Op.131" Bernstein/Vienna Philharmonic (DG 2531 077)
Bill Evans "New Jazz Conceptions" (Riverside RLP-223)
Santana "Caravanserai" (Columbia KC 31610)
Al Stewart "Year Of The Cat" (Janus JXS-7022)

The Bill Evans LP was cleaned using the two solutions several days ago and has been played twice since then. Before playing tonight, dry swept with Decca brush while on the table. All the other Lps were cleaned (both sides) tonight prior to playing.

There is no question that these formulai (formulas?) are very effective at reducing surface noise. All of the air and detail is restored to the LPs, and I think the reason we are hearing this is really very simple: CGMCM Clean Grooves Mean Clean Music. This two step process does a very good job of getting deep down into the grooves and lifting the grunge and getting it off the disc, allowing the stylus to track a nice clean groove. My stylus is staying cleaner, and in the case of the Al Stewart LP, I hear stuff again on it that I have not heard since the day the seal was broke on it in 1977. It's not changing whats on the vinyl, but it's cleaning the vinyl to a degree that allows me to listen to the music, and not the dirt and dust and junk that has gotten into the grooves over the years.

The Evans disc sounds just as quiet and good with just a sweep of the dry brush prior to playing.

I have treated/cleaned over 20 LPs so far and as long as long term vinyl degradation does not become an issue, I am convinced of the efficacy of this stuff.

Dear Paul: Tks for your courtesy.
I think this is an " open thread " and everyone can post an opinion: if you or anyone agree or not with that opinion is another history.
I don't give my opinion for to start a debate, I post my opinion because it is what I think is usefull for to know ( for sure )if there is a true improvement in the music reproduction through your formula treatment or if it is only another equalizer. If you really care about the music reproduction at home you have to try what I'm suggesting you. If you close the door to my suggestion maybe will be because you are more interested on the comercial value of your formula and not on the music reproduction value of your treatment.
Anyway, what do you loose if you can have the answers of the original recording people?.
Regards and enjoy the music.
Raul.

Raul -- while I'm not doubting your kind intentions (nor anyone else, surely) I still fail to understand why & how the application and subsequent removal of a cleaning agent+rinsing liquid (distilled/de-ionized water) on a rotating surface (LP) will affect the electrical properties of the upstream system (=equalisation). That's what you're inquiring about, at least that's what you're saying.
The stylus-groove is a mechanical contact so, the better the contact the better the ultimate result.

If you're wondering whether after the rinsing there is residue left which, in turn, compromises this contact affecting certain frequencies (hence "equalisation" effect)... it really doesn't seem to be the case: most people report less surface noise (removal of particles deleterious to stylus-groove contact) while no-one has reported a reduction of high frequency content after the "cleaning" (which could be an indication).

Ultimately, calling upon the mastering engineers is, I would agree with others above, a somewhat nebulous proceeding for the reasons already offered -- likewise with speaker manufacturers. Rather, you could experiment along the following lines:
Find an original master-tape--> cut two LPs; store 1 LP leave the other out (to collect dust etc). Later, perform a spectrum analysis of each LP. Apply cleaning to dirty LP. Perform spectrum analysis. Listen to "cleaned" LP vs stored LP vs master tape. If game, "clean" stored LP. Spectrum analyse it "cleaned". Listen again, comparatively. Of course, take notes all along.
Copious and difficult proceding, indeed.

At the end of the day, however, this is all just about cleaning the surfaces of a cut vinyl disk and comparing results before & after (i.e. that's what the thread is about). The "testing" conditions, while not rigourously scientific, seem adequate enough for the experiment: same downstream system, same cleaning machine, etc; the application and removal of "cleaning liquids" is the only "before & after" point. It doesn't seem like anyone has reset their riaa equalisation curve...
Cheers
