Shelter 901 MkII

There is a review of it in one of the older Tonepublications on line mag. I'm not sure which issue. I haven't tried it.

Specifications:
Output: 0.55 mV at 1kHz 5 cm/sec
Magnet: Samarium Cobalt
Coils: 6N OFC (copper)
Cantilever: aluminum-coated boron
System body: anodized aluminum
Frequency Response: 20 - 30,000 Hz / DC Resistance: 9 Ohms
Channel balance: <0.8 dB at 1 kHz
Channel separation: 30 dB at 1 KHz
Stylus: elliptical, 0.3 x 0.7 mil diamond naked
Tracking force: 1.4 to 2.0 grams, depending on the cutting angle
Termination: up to 20 Ohms with transformer, within 100 Ohms with phono amplifier
Weight: 9.1 grams

The motor design is different from the original 901, which has the same specs except output 0.5 mV, DC resistance 14 Ohms, and load impedance 20 Ohms with transformer.

A review of the cartridge appears in Issue 24 of Tone Audio.

$2300

Dealer disclaimer.

has anyone managed to compare the orig. 901 against 901 mk.II? what are the key differences?

do these cartridges generally sound better on "modern" (tight tolerance) or "vintage" arms?

I have both 11flat6 (and the 90x). The mk 2 is a bit more refined all round than the mk1, and just as exciting to listen to, but there's not a great deal in it, in my experience.
