Sonotone Audiophile Ceramic Phono Cartridge 

Sounds surprisingly good through the phone's speakers. In Spain we still call hearing aids "Sonotone", like we call coke "Coca Cola" or cacao powder "Nesquik". If you fail to hear what the other person is telling you, it's not uncommon to be told "Do you need a Sonotone?"

It sounds really good to my ears.

I was surprised by this, its rather rich sounding and enjoyable.

Ceramic cartridges have a capacitive source impedance - meaning that their source impedance goes down as frequency rises. If you use a large enough load impedance - say, 500K to 1M Ohm, they can produce a rising low frequency response that more or less compensates for the standard RIAA curve, within a few dB either way. The "compensators" sold for this are merely loading resistors that cause the cart to have a flat (velocity) response, and reduce its output so that it can be plugged into a normal magnetic phono input. You can do that with even cheap ceramic cartridges in the crummiest record players. The one thing I see that sets this cartridge above most ceramics is its low tracking force, which is unusual for a ceramic. It sounds like a ceramic, though. Lots of second-harmonic distortion.

I still have a few NOS Sonotone 9TA HC cartridges. Best ceramic cartridge ever made. It's comes very close to some modern MM cartridges

Just this comment- Perhaps it's the video but the LP looks warped and wore, when you have side to side movement that always means the center hole is not centered. Just something to note... Can you tell me if these are still available or are being produced again?, I'm interested...

So a guy could plug his TT straight into his amp, without the use of a phono preamp? Cool beans.
