Linn Sondek. Sub chassis and armboard. Metal or Composite?

[Collywobbles]

Having changed my subchassis and arm, about a month ago, from an old cirkus steel chassis and laminated armboard to a more modern/rigid version, I have been listening to a lot of vinyl.
The improvements are clear and obvious. My LPs are full of instruments that either I hadn’t noticed before or I wasn’t hearing them. But it still sounds like my LP12 that I know and love.

There have been and are a lot of 3rd party options, ( mainly composite materials, but not all) and three metal Linn options. As I understand it.

My question is, does anyone have enough experience, via listening, to say whether the composite ones have a particular sonic signature sound and whether the metal ones have a different sonic approach.
Or, do they all sound a bit different due to design differences and not because of what they are made of?
The price difference between the most expensive and the least expensive is “about” a factor of 10.

Interested in peoples experiences on this.

I Have no experience of later Linn Rigid assemblies , But did try a Russ Andrews Torlyte Arm Board, Sub chassis, and i think Plinth back in the day fitted to a 3 leg Torlyte Stand and yes it did work with a sweet sound and maybe better than some of the Linn upgrade variants which have been a bit hit and miss in my opinion. Back to subject - well if you change the material you will change the sonic signature via different harmonic influences. Also design structure and various rigidity factors will have their own influences. So it is one or both depending on what you fit.
