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.

I have to agree with bassdude. I have owned the 40’s and currently the SHL5+ and tried Quicksilver V4’s, Quicksilver Mono 120’s, and had a long term loaner Audio Research Reference 75 SE Stereo Amplifier and none of them worked well with the Harbeth’s. I owned QS amps for years and they worked great with my Vandersteen's and I still love them.

My Harbeth’s sounded so much better with a Musical Fidelity Tri-Vista integrated amp, with the 40’s, and with the Aesthetix Mimas and the AX7e on the SHL5+. I just don’t think Harbeth’s and tubes mix. To me it sounds like someone threw a blanket over the speakers with any of the tube amps I tried. But this is my personal opinion and YMMV. We all have different listening preferences and only our own ears can tell us what we like. Also, Harbeth uses Quad SS amps to voice their speakers.

I've used 3 solid state amps and 6 tube amps with in my 9 years of 40.1 ownership... and tube amps are my resounding preference.  But what do I know.

@bassdude

Makes perfect sense they would show their speakers with the mega watt amps in a public forum, BUT in a real world situation like your home where one MAY want something smooth, musical and warm, softer non fatiguing.... ALWAYS ALWAYS go for the sweet tubes of at least 50 watts at 8 ohms to meet what Alan has spec’ed himself as the minimum requirement. Now home theater solid state all the way!!!

Just so you know... that is Harbeth Support speaking... not me.

They are the ones that say they only use SS amps to design, voice, test and market their speakers, because they sound better to the general public when driven by the types of amps they design their speakers with.

It may be that some folks prefer a more relaxed, warm, slow sound to the clarity, resolution and PRAT, that SS amps produce with Harbeths - which is my preference... more like the... incredible sound of ATC’s, Ocean Way's or Magico’s, etc. - though, Harbeth’s do not rival those with any type amp.

It's all about personal preference.  I find I find Magico's to sound very nice, but ATC's to be loud and grating.  

Reading the original posters preferences for tubes and listening to jazz at moderate volumes, recommending high powered solid state amps is not in his best interest.
