..................I did some research on ART9 before buying. According to an insider at Audio Technica (Japan) the ART7 is more for classical music because it has better micro layering of soundstage. ART9 on the other hand is a much more of an all rounder because it has a very powerful presentation which suits Jazz, Rock and Pop along with classical. ART7 doesnt have the macrodynamic force that the ART9 has. Moreover ART7 is an extremely low output cart making it a difficult cart for phonostage matching. The ART9 is much more friendly in its output voltage and matches with any decent phonostage. The loading needed for ART9 is between 100-120 ohms.
I do not know what price you are expecting for an ART9, on ebay it is mostly listed for $1 -1.2k. I have never seen it cheaper. In fact Audio Technica has been very silent about these carts. There are no known reviews of it. In Japan though it has received many awards and it was one of the Japanese audiophiles who told me that it is one of the super cartridges out there. While insiders know about ART9, outside Japan it is a mystery.
อาจต้องดูเรื่องความคงทน เพิ่มขึ้นมาครับ ว่า มีความทนทาน แค่ไหน ?
