Compatibility with Rega brand TT:
REGA brand cartridges’ height from stylus tip to the top cartridge mounting surface is lower than Standard.
Therefore you would need spacers to ensure the correct set-up of the Ortofon cartridge.
Adjusting the height of your Rega tonearm is easy with Acoustic Signature's Spacer Set. It allows you to adjust the height from 0.5 mm to 3.5 mm in precise steps of 0.5 mm - without removing the tone arm. Simply loosen the screws, insert the AS-spacer, then lock the screws back down, and you're tonearm is ready to play. or fit Headshell spacers or shims between cartridge & headshell
3.2 - 4 mm spacers should be enough for 2M cartridge.
2 - 3 mm spacers should be enough for Quintet cartridge.

Rega arms have fixed VTA & Azimuth ( 1%)
all other arms have variable VTA & Azimuth ( 99%)
2.3. Azimuth, vertical alignment
Azimuth adjustment or vertical alignment of the cartridge is very important for optimal channel separation.
The checking is easily done by lowering the cartridge onto a thin mirror placed on the record surface and examining whether the reflection lines up square with the cartridge, when viewed from the front. During this test tonearm must still be parallel to the record surface. If not obtainable because of mirror thickness, remove record and work directly on the mat. If alignment is still incorrect and not adjustable because of fixed headshell, the only solution is to resort to packing on one side of the head-shell.
2.4. Tonearm level, Vertical Tracking Angle (VTA)
Cartridges are constructed so that cantilever angle corresponds to the 20 deg. record cutting angle, when the cartridge is loaded with recommended tracking force and the cartridge base is parallel with the tonearm and this again is parallel to the record surface.
