I never realized the 12" version is more expensive dis-proportionally. Miller, you're very correct about bi-amping! Similar to when stereo came out and a husband had to explain to his wife why "they" needed another amplifier and another Hartsfield in the living room!!
Why Do 12" Tonearms Cost So Much More Than 9"?
For example, the Tri-Planar 12" arm is $3600 more than the 9" version. SME tonearms are similarly priced.
Is it really that much more costly to develop the longer tonearms?
