Basis Super Arm 9

I am new to the basis family moving from a loaded LP-12 to a 2800/Vector 4 in January.  I am seriously considering upgrading to the SA9.  Most if not all of the older opinions posted were all positive.  If anyone has more recent experience and/or moved on from their former opinion I would appreciate hearing your feedback.   Associated equipment would be Aesthetix Rhea, ARC, Manley Neo Classic Mono's and Maggie 3.6. Cartridge is Hana Umami Red. Once again I appreciate your feedback!
