Sony MD2000
The only real answer to TDK MD-RXG pro.
Not by the merits of the technical characteristics of the real "pro"; for me are overrated.
The MD 2000 comes with a beautiful silver - gold color of magnesium; the initials of the blank engraved on the front surface.
On the front of the shutter, there is a serial number; on rear the blank is secured with 5 microscrews.
The case is very nice with the front window fumè.
It's hard to say whether it is nicer than the Sony or TDK; definitely the Sony was much more expensive than the TDK.
To evaluate that TDK has taken over the design of a compact cassette to produce Pro, while Sony has created something entirely new and magnesium is harder to work than aluminum.
Not easy to find, very high prices.
