High end turntables Why? 2 tonearms

Hello denziens of the analog lounge,

After looking at many high end statment turntables such as the antique Thorens reference to the latest word from Teres in direct drive the Certus 460. I am intrigued by this option. It reminds me of a cutting lathe more then a TT.

Would not the extra arm affect the reproduced nuances of the musical sound as much or more even then say a brass tone arm holder vs aluminum vs stainless steel vs wood to infinity and beyond?

Is this a way to have two approaches available when listening say to acoustic recordings and then a different point of view for classical or jazz with the other arm on the same platform ?

Would one have say two identical arms with different pickups or even two different arms with two different pickups.

Is there an advantage to two arms over two turntables other then the size of the foot print?

Your opinions would be appreciated. I am about to upgrade from my old but once state of the art JVC QL Y66F which while protecting my vinylhas always been "not as good" as the AR it replaced in 85. I love the Michell TT's as well as the Teres. I am not thinking about two tone arms, one Schroder will have to do.

This is just a way of introducing myself to the ladies and gentlemen of the forum.

yours truly
Joseph
