I have a fully modified Michell Gyro. Twin spiders, the Orbe platter and clamp, and the H.R. power supply. I run an SME V on it and use it with a mono cartridge exclusively. I love it and I am not suffering any audiophile anxiety at all.
A good turntable shelf, the Orbe clamp, and the H.R. power supply would be the only modifications I would consider. Go in steps so you can judge what is happening. The SME tone arms are often criticized for being too analytical, but they are accurate and reliable with outstanding low frequency reproduction. They were the arms that John Michell used as a reference when he was designing and building the first Gyro's and Orbe's.
Go slow.
