The enclosure of the 95 is mostly aluminum. The top is plastic. Some people disagree with your body material assessment, thinking the 150 deluxe body is unnecessarily heavy and the plastic is better damped.
Some others say the CA V2 has too much wood. I wouldn't know.
The AT 150 and 440 are entirely different in both generator and stylus. Lowest inductance is TOTL, but you can get similar motors in the 100E and 5V bodies - same stylus fitment. The 120/440 body has the same basic motor as in the 160ML, 155LC and many of the AT classics. The 490mH generator was their go-to TOTL for years. It's generally easier to get flat response with it. Put a 150 stylus on a 440 and it's silly good.
CA makes a $15K cart. Why would they want to reinvent the MM ? The 95 is the perfect candidate for modification. Its 400mH motor splits the difference between the 150 and 440 and is a dream come true in the budget category. AFAIK CA never lied about their MM origins and they can't be expected to advertise it. I like my Virtuoso. You can even use a trimmed 3472 series P-mount stylus on there and it's even better than the 95 replacements, but I read that Soundsmith now offers boron/micro so you can turn it into a virtual Maestro/Virtuoso.
