Ortofon SPU with 12 inch Jelco arm?

This is very strange statement regarding vinyl from the 60’s & 70’s. Most of my vinyl are from this era. Why do you think the elliptical shape is better? And why do you think the SPU is the right cartridge for those records?

Most likely vintage (old) vinyl are slightly worn by the conical tip, it was the most popular stylus shape, especially in the 60s. Right?

You need Shibata stylus tip to play worn vintage vinyl. Shibata stylus goes deeper in the groove and this area of the groove walls is untouchable by the conical tip (think about it). You can improve the sound quality by using Shibata stylus for your worn vintage vinyl from the 60’s and 70’s. But elliptical stylus can not improve the quality at all. Line Contact stylus is the one you need!

Thanks for your response Chakster. Perhaps I’ve been misinformed to do with tip shape. That’s why I asked here.
My choice for an SPU is simply something I wish to try. I’ve also read some of the Ortofon SPU’s are a good match for someone with beat up older stereo LP’s.
 I’ll research shibata tips. Thanks 

@mid40sguy i hope you already checked this SPU thread:

The problem is that SPU only comes with Conical or Elliptical, except one model called Royal GM and Royal G MKII with Replicant 100 Stylus. In shape, this looks about as much like a cutting stylus as you can get without having a cutting stylus; it appears to be a true line-contact tip, and its specified dimensions indicate that it is a very thin line. It's huge upgrade over the oldschool SPU with conical or elliptical styli.
Ortofon Royal G mk2 is the best SPU in my opinion.

If you don't use styrene pressing (vintage 45s). The Replicant 100 is the best for used/worn records as this is actually a true Line Contact stylus.

But you can check some other cartridges (even MM) with Line Contact styli such as Stereohedron, Shibata, MicroLine and Micro Ridge - this is how it looks under microscope. 

A friend and me have compared a couple of different SPUs
in the last couple of months.

First the match of a Jelco 12" and a SPU with G-shell is a very
good one. This is due to fact that the Jelco is built for a distance
(headshell base to diamond tip) of 51mm which is exactly what
most G-shell SPUs have.

Secondly you can balance the weight of a SPU with the counterweights
easily.

Thirdly in our experience the SPUs give a great value for money
plus they are outstanding in playing old analog recordings. 

Our current favourites are the Synergy GM if you use a "normal"
phone stage. It has an output of 0,5mV at 5cm/s and sounds
extremly sweet, involving, and "SPU-like".

If you use a high gain phono stage or a SUT (step up transformer)
my recommendation would be the new SPU #1 E GM. It gives you
a real impression of the very special SPU-sound for a really good
price tag.
