Nottingham Analogue Ace Space 12'' vs Ace Anna 12''

[oym]

Hi, I have an old Nottingham Analogue Space Arm on a Hyperspace, using Benz Glider (0.8).  I am looking of replacing the arm and considering the NA current models.   Has anybody had the chance to hear the difference between the Ace Space Arm 12''  and the Ace Anna 12''.  They look nearly identical but the Anna is much more expensive nearly double the price.   Would be grateful for any feedback on this.   (I am also considering Moerch DP6, SME 5/M2-12, Origin Live Illustrious and Audio Origami PU7)

thank you very much, OYM
