I would have:
a) Pillar device for VTA adjustment while playing.
b) Cup device for damping adjustment while playing.
c) 12" tonearm.
d) Motor speed adjustment screw on TOP of the chassis, not at the rear.
e) Separate rear metal plates for signal outputs/ground and motor power input (as in Simplex).
f) Signal ground not connected to chassis ground.
g) Choice of XLR/5 PIN/RCA outputs.
h) Accessible from above Allen screw for (eventual and unlikely) cartridge alignment .
i) Option of "Baltic" plywood plinth (as in Versalex).
j) Improved, dedicated power cable between the DPS/ Amadeus motor.
Dear Mr Firebaugh and Mr Denson, I'd gladly pay for any of the above. Notwithstanding the fact that the Amadeus is already a benchmark in analogue.
More ideas?
