I use CH Precision P10 phonostage and use its current mode. There is no need to worry about the loading, so I don't know the best ohms for voltage mode.@TLi yes it does set a new standard. I've been playing with loading from initially 600 ohms to 248 then 404 to 324 and lastly 358 ohms. The numbers are based on using RCA plugs with different value resistors. So far the 358 sounds best but values can vary based on one's phono unit. After 1 month playing the Sig Diamond into a MC section will try it with a SUT.
Please keep me posted what loading you find best.
Enjoy
The Platinum is my go to cart so much so that I acquired another unit for my place in Australia. Other carts are played less in deference to the Platinum. Maybe I should also think about the DiamondHey @Joel27 it's been 9 months since we posted in this thread. Thought I'd see if you received your Sig Platinum? I've only had my new Signature Diamond for a few days and playing with loading values but I can say I don't think I'll ever consider another cartridge. I'm over the moon and the next planet and the next. Hope some day you will get a chance to hear one.
Happy Listening
