I haven't but if I may make the following comments...
The Pharaoh is a solid state power amp combined with a tubed preamp section. Its power amp is also Class D vs. the Class A/B in your Luxman so this alone would mean a big change.
So if you want to add tubes, why not just add a tubed preamp to your Luxman's Main-Ins jacks to see how you like it first?
