Where do classical vinyl records get their rumble from?

@richardbrand 

"...their systems, including tables, are simply not resolving enough to hear what I report.  Alternatively, the noise floor of their listening environments could be so high that it masks the effects."

These are just a few of my faves;

Clifford Curzon - Beethoven "Emperor" Concerto No. 5 in E flat for piano and orchestra, The Vienna Philharmonic Orchestra, Hans Knappertsbusch, Decca Stereo 1958

Georg Solti - Beethoven Symphony No. 9 , Lorengar, Milton, Burrows, Tavela with the Chicago Symphony Orchestra and Chorus, Decca Silver Jubilee Recording Stereo 1972

Bruno Walter - Beethoven Symphony No. 6 in F major opus 68 Pastoral Columbia Symphony Orchestra Stereo 1958

Gyorgy Sebok, Janos Starker - Johannes Brahms Sonatas for Cello and Piano E minor opus 38 and F major opus 99, Mercury Living Presence Stereo 1964

Antal Dorati, Janos Starker - Dvorak Violoncello Concerto in B minor Opus 104 Bruch Kol Nidrei Opus 47 London Symphony Orchestra, Mercury Living Presence Stereo 1962

My equipment will out resolve any thing you’ve got and no rumble. So where do you live? In the Outback?

Recording technology has come a long way in the last 50 years. 

I am glad you have no rumble.  I believe you posted elsewhere that you have no surface noise either.  You have a truly miraculous system.

Of course, none of the works you cite contains the dynamic range of a Mahler symphony and these days vinyl has digital to compete with.

Yes, and any half-baked argument will do won’t it Richard, especially when you deliberately take my statements out of context. I’ve commented extensively about handling vinyl and simple, inexpensive methods of cleaning records elsewhere in the forum that you deliberately ignore but only focus on the ones that really don’t bolster what you’re disputing in the moment. You mention advancements in recording technology when you preface this thread on a recent Deutsche Grammophon recording that by your accounts contains rumble and I just simply pointed out multiple examples of very old ones that don’t. Anyone can read the inconstancies in your incongruent arguments. Why is digital suddenly a fallback position when we are discussing vinyl? Also, attacks on my spelling and grammar? Hm?

I will go on to say that yes there are advancements such as superior stylus profiles over the biradial elliptical which tracks very close to the surface of the record much like a spherical where most of the groove imperfections are and it’s only real advantage is it’s ability to resolve high frequency information slightly better but is just as susceptible to pick up surface noise as well. Line contacts, Micro lines and Micro ridge ride deeper and contact more pristine groove surface significantly reducing noise.

The bulk of the noise that accumulates on vinyl over time is the result of lackadaisical handling and improper hygiene. Record noise and wear are not an absolute and there are countless examples of vinyl’s permanence as a sound storage medium dating back to it’s beginnings in the late 1940s. I believe I’ve said this elsewhere too.

You want to hear dynamic range then get a copy of this Buddy Rich - Just In Time - The Final Recording on Gear Box records. Buddy has a very long solo on the third disc that perfectly demonstrates dynamic range and the incredible low noise floor vinyl is capable of in a live setting!

"1kHz/5cm/sec"

Yeah, well beat me about the head!

@richardbrand 

"That’s the standard for measuring output voltage of a cartridge."

Copied from Shure PDF leaflet. You’ll note that Shure expressed trackability as cm/sec. I don’t see 1000 Hz there do I?

"why does everyone equate warp information with rumble?"

@richardbrand 

"That was what you originally posted, followed by"

"Hopefully you have only one warp per record, so it will have a fundamental frequency of roughly 0.55-Hz, which is in the wow range below 6-Hz.  A bit higher up comes the flutter frequency range of 6-Hz to 100-Hz.  Meanwhile rumble is usually below 30-Hz.  Of course the Japanese measure these things differently."

@richardbrand 

I wasn’t asking and another example of how you like to take things out of context. My actual remarks. -

"After some thought I attempted to edit my post for grammatical errors but @pindac was about to commit his comments which superseded my edits before I posted them. So here they are.

...it will never work if the cartridge’s compliance and mass wasn’t chosen for the tonearm’s in the first place. The resonance will forever be too low or too high which will either accentuate warp information if too low or affect tracking and bass response if too high. 

Secondly, why does everyone equate warp information with rumble? Rumble is a mechanical artifact of a poorly designed, machined or damaged main bearing and as the platter spins, the noise generated is transferred up through the platter and the vinyl and is then picked by the cartridge and often sounds like a faint cyclical roar in the background during quieter music passages. I used to think it was groove roar until the quality of the turntables I was using improved and had much better fabricated main bearing’s, thus the phenomenon became forever inaudible."

Obviously, the previous post doesn't directly address your DS Audio but it appears you have a vendetta and would prefer not to have the competition. Your BMOC days ended generations ago.
