Thanks Tom, I looked up
https://www.vinylengine.com/cartridg...&submit=Submit and
the IKEDA 9TS comes in I think with resonance at around 10hz, with Compliance 7 x 10-6cm/dyne(presumably @ 100hz as Japanese cart) so this should be around 12X10(e-6)cm/dyne @10Hz, with SME effective mass 10/11gm and cartridge weight plus bolts 11-12gm. So this would be OK, I think?
The Phasemation PP-1000 resonance I think will be around 8hz with compliance 16X10(e-6)cm/dyne @10Hz, SME effective mass 10/11gm and cartridge weight plus bolts 14-15gm.
The Transfiguration Pheonix S resonance I think will be around 11hz with compliance 12X10(e-6)cm/dyne(presumably @ 10hz), SME effective mass 10/11gm and cartridge weight plus bolts 9.5-10.5gm.
The Lyra Kleos resonance I think will be around 8-9hz with compliance 12 x 10-6 cm/dyne at 100 Hz (I think this will be about 18-20 10-6 cm/dyne at 10 Hz), SME effective mass 10/11gm and cartridge weight plus bolts 9.5-10.5gm.
So from the compliance point of view it looks to me that any of them should be ok in the SME IV or V, if I have got anything wrong then please let me know. The Phasemation sounds interesting from reviews but your take on the IKEDA is appealing although I would go for the 9TS for higher output.
