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.

Try a Carver 275
replace middle 12AX7 with Gold lion and you are Done! Return policy is Crazy and sound is superior!
I’ve tried many! I’ve kept my Airtight 300B reference and the Carver 275.
nothing to lose except the best sound your system can produce!!

So I doubled down and traded in my LTA z40 integrated for LTA separates - Microzotl preamp and a pair of ZOTL40 Reference run monoblocks. Getting close to 100 wpc at the 40.2 Annie 6ohm impedance and results are quite apparent, quite spectacular...really some tubey magical midrange, serious dynamic sound.  Yes I was mistaken- they do love some current! And double Quads of NOS Mullards XF2s!

@aj523 can you please elaborate more on what are the improvements?  My MC275 also can be switch to mono @150W.  So, I may buy another 275 down the road, but it is expensive.

alternatively, there is a MA6600 for sale locally with 200W per channel.  However, it is a SS, and i am not sure if I will like the sound.  But I will never know until I try it, I guess.  If it works, I can then sell my MC275.
