New 55,000 Euro tonearm

I guess Mikey's already bought his.

And some oligarchs who still have a bit of disposable.

SAT is too much bling for me.  With that amount of bling I seriously question if the designer is really wedded only to good engineering.  He talks the talk.

@optimize    If you are getting extra bass from LPs, your funk Houdini (nearly the right name) is probably just adding resonance (NOT subtracting it as you say).  You are not getting more of what's in the groove; the resonance is just amplifying it.  Take it off, bin it and get back to listening to the music.

Having researched further the Houdini cartridge decoupler and the principles behind their arm, I learn that their idea is to decouple the cartridge from the arm by securing it to the arm with a non-rigid fixing.

This is just about the most stupid idea ever conceived in the history of recorded sound.  The principle of sound reproduction via LPs is that the stylus is fixed rigidly in the arm which is only allowed movement in lateral and vertical planes, i.e. no twisting or turning.

The reason for this is plain.  If the stylus is allowed to move whilst it is tracing the signal recorded in the groove (other than movement induced by the groove's modulations), distortion will be introduced, i.e. signals other than those recorded in the groove.  Movement of as little as one micron will introduce distortion.

Most reputable designers of tonearms have gone to great lengths to ensure a rigid cartridge fixing and bearings with minimum slack, only for Houdini to magic it all away.

@optimize     non-rigid cartridge fixings also introduce unwanted resonance into the signal.
