Class A or AB Solid State Integrated Amp for Spendor D9's - Coming from Tubes

I think you’ve got a pretty damn fine list and not sure you could go wrong with any of them.  I’d only add to the confusion and suggest putting Vitus on your list as well.  Or maybe a hybrid like Unison Research Unico where tubes only in the input stage.  Best of luck. 

Speakers are semi at 90db. 
 Don’t let this deter you from a high powered amp.

 Get min 300WPC!
YOUMWILL NEED THE headroom for crescendos and power chords.

 Little 5, 10, 100,,150, 200,WPC amps,,while great, there is no match for 300WPC plus in this business.  
Thank me later.

 My speakers rated at 250W.  I use 650Wpc/rms. Exclusively, always a flawless sound, no clipping of any kind. Everything is just sublime!

 Don’t believe the hype, watts are your friend.
any good high quality amp is great.

 go big, or go home.
 Will a 100W amp sound good, sure, will 300 W sound great,...YES?
effortless, easy going, tight bass,  ice mids, highs, and all the above!

 Enjoy

 

I own D7.2’s and a LM805ia. You probably know this, but a sound profile like the LM is a bad match for TV/movie audio, where one actually does want sterile/analytical with lots of watts. If you must combine the music and tv in one system, I think that @jjss49 recommendations were very good. Move the warm/sweet/tubes to the music source/stage before quality SS amplification. Lumin is a good streamer but you could improve  sound with a separate tube dac/line stage. Unclear on how you are sourcing your tv audio input but if you could find an integrated amp with pre-in/bypass then you could use that for the music side and use a ‘normal’ input with volume/gain for the tv source.

Parasound!

Currently using the Ayre VX5/20 175 watts/channel into 8 ohms with my D9s with excellent results. The Ayre AX5/20 integrated should be on you list.
