While I have not heard the gear you mentioned, I can tell you a bit about Luxman amps.
They can drive speakers with authority. The overall signature is balanced with articulate midrange and treble. Bass frequencies are tight and resolving.
Tube amps in general add warmth to midrange and treble and may soften bass frequencies. In other words, a song with strident midrange or treble can be tamed by a tube amp. On a SS amp, all of those peaks and drops may sound annoying.
