Agree with @yoyoyaya that the Safir is quite expensive for its performance. A Tri-Planar U2 SE or U12 will outperform it at half the price, and it will be a better fit aesthetically for the Luxman table.
I am a Tri-Planar dealer with a very close friend nearby that owns the Safir arm.
I should also mention that I am an authorized Grimm dealer, and to match the presence it can deliver, while the Tri-Planar would be an excellent upgrade, you can also experiment with rolling tubes in the EQ-500. By default, the EQ-500 is a bit overly laid back, and rolling to more transparent tubes will yield much better results.
