Where to insert tubes while running a Luxman SS integrated


I've recently upgraded my integrated amplifier from a Cambridge CXA81 to a Luxman l-507uxii.  The Cambridge is definitely not bad for its price, but the Luxman is a different animal and is making me want to upgrade everything else in my system.  Which brings me to my point of discussion: I'd like to insert tubes somewhere in my system to get some additional warmth and a more holographic soundstage.  Would adding a tube preamp and running the Luxman as only a power amp be best to do this, or would it be better to get a tube dac for my digital, and separately, a tube phono stage for my vinyl?

i understand the need now... luxman solid state into kef r3 will take no prisoners with poorly recorded music -- treble lives close to the bleeding edge

try to find one of these units on the used sites (the links are to already sold listings), they will preserve the musicality while dialing back the unwanted sizzle and bite

any older model van alstine tubed dac on the used market (they are all excellent in performance and value)

Thanks for your dac suggestions @jjss49. Yes, the Luxman R3 combo is very revealing, including of recordings with harsh treble. I was surprised that the highs are a bit smoother than with the previous amp (the CXA81), though.
