SME V tone arm advice

Thanks all,
jperry, using a Prism Orpheus as my one and all pre/Dac. Decware and Sim amps , Grand Veenas complete my quiver. 
Soundsmith Aida MI  has my interest right now. 
Actually id like to simplify  and Lyngdorf may get my business as an all in one. 
Spatial, Dutch,Dutch; and Tekton may also be on the horizon. Appreciate your interest. 

Keep the SME V for sure! Personally, I use an SME IV, fitted with a Clearaudio Maestro V2 Ebony cartridge, on a Michell Engineering GyroDec (full plinth, not SE version) and could not be happier with the results. See my previous post on this system:

Last night my wife and I listened to the new MFSL, 45 rpm, one-step (UD1S) release of Simon & Garfunkel Bridge Over Troubled Water. Wow! Can’t believe this recording is nearly 50 (48 for those who are pedantic) years old. Unbelievably quite background and wonderful rich sound. To me, this is as good as vinyl gets.

I have a Sme IV with Ortofon Mc3000mk2 and Gyrodec full up-graded for 30 years.

SME series 309 - IV - V and Gyrodec like some other models of different brands (Denon DL 103 for example) resist for 30 years and beyond; there will be a reason!
Do not give in to the temptation of novelties!

the prime is not an upgrade.

Just pulled the trigger on a used GyroDec Mk V. Thanks to everyone for the perfect advice. Can’t wait!
