No experience with different stands. Mine are the Diva Stand 1 Exclusives that are pictured with different spikes on the website. I advice to fill them with sand (3/4 up only, I had a definite feeling the sound became sluggish when filled entirely).
As to the amp, I happen to be an old Luxman fan myself (the L-410 was a long time companion) and without having heard any combination with WLM speakers, I guess they should match wonderfully (audition if you can, if it were only for the fun of having the Lux a few days in your system). Apart from the tone controls, you may find the integrated phono pre a real treat. Then again, I have to echo Markuss words, the Divas love tubes. Remember also they come with treble control and then there is the optional Diva Control for the bass. Sorry for adding more complexity to the overall equation there!
