Tube Rolling Luxman D 380

Luxman recommends at least 50 hours of run-in time for the D-380, but its solid-state output sounded good right off the bat. Burning in the tubed output stage did take all of 50 hours, however -- its sound was a bit wonky at first, then it settled in nicely. Switching between solid-state and tubed output and between Filters 1 and 2, I gravitated to tubed and Filter 2. This combo sounded more organic, with slightly better bass. Filter 1 seemed leaner and more detailed, with a touch more top-end extension and clarity, but also tended toward sibilance with some music. But I heard less difference between the tubed and solid-state outputs than between Filters 1 and 2 -- both sounded, for the most part, rich and involving.

For some reason I resisted the urge to buy that SQ-38D, but it’s stuck in my mind all these years. Now, I’ve just had a second chance, in a way. Luxman recently released the D-380 CD player ($5495 USD), a stylish model whose classic looks -- that familiar and distinctive wooden case -- hark back to the glory days of this tradition. It also has solid-state and tubed output, selectable by the user, and a 32-bit DAC.One Cognizant Portal
 

I decided to change the tubes in my Jungson Moon Harbor CD player. ... Both players use the same D/A converter and transport mechanism, ...https://innoutsecretmenu.online/

I'm looking for an audio system for music and also a bit for movies. Actually I would have planned with two floorstanding speakers, sub and AV receiver but I just don't have the space.

Would Sonos Arc be an alternative with the Sonos sub?

If I want true surround, I could still upgrade with small speakers (Sonos One SL) in the back https://showbox.tools/.

Disadvantage is, for this price I would also get a budget surround set with receiver.

Have you listened to this player with the tube buffer circuit in, and then not in?  How much of a difference do you hear?  If very little then it seems to me tube rolling is not in the cards.  Or maybe its exactly what is needed?
