Just to add something to the discussion. I have an Ortofon A90 in a Rega RB 1000 tonearm, mounted with the Cartridge Man Isolator. I have adjusted the arm height using spacers ( as the RB 1000 does not have VTA adjustment ). I paid much more attention on other adjustments. The correct cartridge aligment was got by using the Feickert protractor as well as using the Cartridge Man digital level made a huge difference in the sound( it is essencial ) The final adjusment was made using the Hi Fi News LP .
The A90 is amazing and it seems a very good match to the RB 1000.
