What tube amp for Harbeth 40.1

I am looking for a tube amp for Harbeth 40.1.  I know many suggest SS amp such as Accuphase, Luxman, Hegel, McIntosh ... etc for Harbeth, but I decided to keep it with tube.  I also don’t think I need a lot of power.  I currently have a 8W custom built 300B and had a 18W Almarro 318B, and to me, they sound fine.  However, I think more power will help, and I never know what I missed until I try it out.  Having said that, I don’t think I need crazy power.  Anything 30-80W is good enough for me.  I am 3m away from the speakers, listen to Jazz at avg 83dB.

i have the following short list:
1) PrimaLuna Evo 400 integrated
2) Leben CS600X 
3) Linear Tube Audio Z40

Which one do people like with Harbeth?  Any other suggestion?

Among all qualities, I value holographic presentation the most.  I really like the feeling as if the singer is floating in front of me, if you know what I mean.  And my current 300B do pretty well in this regards, and I read this is what SET amps are good at.  Will I be disappointed with the above?
Thanks.

Hi bassdude, just so i understand are you saying that if a piece of music like the second jazz piece they played on Alan's 2015 YouTube video from this thread which hit a top transient peak of 30 watts will have more clarity, resolution and dynamics if the amp is a SS vs. a tube, both delivering those same 30 watts?  Really?

Ayon Triton III Integrated worked well with Harbeth SHL5 +, triode or pentode options.

Have used Prima Luna separates.  Everything said about them is spot on...

My two cents...
I use a vintage restored McIntosh MC240 that sounded great with my Harbeth 40.1 (I no longer have). Looks awesome as well, it's definitely a showstopper when people come over.
My audio club friend drives his with an Audio Note Oto Signature SE. It sound fantastic as well and it's surprising what a low wattage amp can do.
With all that being said, I was on a trip to Southern California and visited a dealer down there who played me some Harbeths 40.1 driven by a Quicksilver integrated amp. I was floored, still am, by the sound that came out of those speakers. Now let it be said that his room was totally set for music like mine will never be but it was outstanding.

Aren't all those units tube based amplification?
