The last both postings about
http://www.diyaudio.com/forums/anal...-technicas-50th-anniversary-mc-cartridge.html
don't provide any advices. Therefore I open a new thread.
In this case there I have found this threads:

According this threads and others the ART-7 is more suited for current control inputs (transformers or Pre-Preamps like Hiraga or Mark Levinson JC-1/JC-1DC due the low inductance (air coil) and thus low voltage output)
The ART-9 is more suited for currently usual phono stages with voltage gain select (MM/MC switch) and voltage control inputs (due the high inductance of the internal coil and thus high voltage output), i. e. high input impedance of the preamp input. The suited impedance adjust was created through real resistors between input and GND.

But concerning the sound differences there are also no hints.
Who had do perform a listening test between this both cartridges?

Here the data sheets:

Mr. Rodrigo Thomaz from Audio Technica send me follow reply to this question:

Hello,
if you prefer to listen to multiple orchestrate classical music, we
recommend the Non-magnetic Core Moving Coil cartridge AT-ART7.
It can reproduce more sensitive sound of each instrument.
However
if you prefer more dynamic music like jazz/pop music, we recommend you
use the Magnetic Core Moving Coil cartridge AT-ART9. It will deliver
much more presence with rich low mid frequencies.
Hope this can help. Kind Regards, Rodrigo Thomaz

I think, this is a first helpful advice to make a decision for the purchase.

A friend of me has now the ART-7 in use and sonic character isn't good. Some load resistance was already checked without success. Midrange is too hard. The reason is clear after looking the frequency response, which is added to each cartridges in this price class.
There is to observe an enhancement of the level startring from 1000 Hz until 14 KHz about 3db. From 14 KHz until 30 KHz additional 4 db. Last part is to compensate with a load resistor parallel to the cartridge coils. But additional low pass filter is necessary to compensate the first unwanted high pass function.

Who can upload your own ART-7 frequency response to compare your versions to the versions of my friend?

Thank you.

I can but I need to borrow an ADC from my neighbor. Sold mine!

Thank you.
