Is this why my analog rig isn't so hot?

Dear friends ( all of you ): I have to return to by first two answers on the George subject: it has electronics problem and to get the Myabi cartridge, let me explain it:

George: go to the source, the phono cartridge, is where all began, we can't do anything for an improvement in the signal when that signal already pass through the cartridge the best we can do is not to degrade the signal, almost imposible, or better: degraded less. George if you want a better quality sound from your analog rig then you have to start with your phono cartridge, I already told you the Myabi because there will be a sinergy with your audio system and this is a plus, but there are other top options in phono cartridges. If you go with the Myabi you don't have to worry about the tonearm match ( you already have it ), this subject is extremly important and sometimes missunderstanded.
George you don't have to go around and around and ....., you have to go to the source: phono cartridge. After this you can ask: how I can help for degraded less that critical cartridge signal?
Regards and enjoy the music.

Yourmama,
Very LF signals are easy to find on vinyl. Just break out your HFN test record and play the resonance measurement tracks. Paul and I both hear clean test signals down to 16Hz on our Teres 265/Tri-Planar VII/Shelter 901. On actual music the bass is tight down to low organ and string bass notes. Those aren't at 16 Hz of course, but 32 is not a problem - 'Zarathustra' and Bach's 'Pasacaglia' come to mind.

FWIW, before we added the Tri-Planar we had a modded OL Silver. Nothing was audible below 24Hz on the HFN record IIRC, and even 32Hz tones were both rolled off and muddy. The Tri-Planar seems bottomless, which I suppose it should be for the price.

I'm not sure why you think the N803's can't go below 60-70Hz, they're specified as flat to 33. Of course those 24/18/16 Hz test signals become progressively less loud, but they seem pretty clean to our ears. If someone else's N803's are boomy or absent from 33-70Hz then there's definitely something wrong with their system or their room.

In addition to our tonearm change here's another firsthand example: my old SAE amp, though it had nearly as many wpc as my c-j, couldn't take the N803's anywhere near as low without losing control. In fact one of my first A'gon threads was about finding for a cure for boomy bass. The amp was the answer.

Also, I've heard Cello's very nice system, which includes a Rel Storm. Obviously that goes lower and stronger than my N803's, but the difference is only in the 32Hz and below range. The N803's are just as full and tight as his system from there up.

Newbee,
I trust George gave up and bought concert tickets long ago! Or at least I hope so.

Dear Doug: I agree with yourmama on this 16Hz subject: for any one can " hear/feel " a clean 16Hz frecuency it has to have not only the audio system that has the capacity to do it but it has to have the room for that frecuency and their harmonics can " form ".
I don't know nothing about your room but your audio system ( like a whole system ) certainnly ( I'm sorry, but the english is not my native language ) can't to reproduce a clean 16Hz frecuency by any circunstances. It is not a matter that " 16Hz test signals become progressively less loud ": by physics law your loudspeakers can't do it, period. As a fact there are only a very few subwoofers that can do it in the right way.
Doug, here you are talking about to reproduce the most difficult task for any audio system even with subwoofers.
Regards and enjoy the music.

So what are we hearing then?

harmonics of different fundamental frecuencies.
