Tube Rolling Luxman D 380

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?

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.

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/

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
