Tube Amplifier Sound Characteristics


I wish there were a scatter diagram one could put together of tube amp sound qualities. The reason I say this is that today's tube amplification can range from sounding warm and romantic to cool and solid state like.
I like the sound of VTL, Quicksilver and Antique Sound Labs. I am in the market for a tube power amp and as I shop I see where more and more amps do NOT sound like tubes at all. So where would the sound characteristics of the 3 amps I mentioned be? For example I was considering the ARC Ref75SE but owners tell me it is SS sounding. Your thoughts are appreciated.

 and more amps do NOT sound like

All tube amps sound the same to my ears, 34,88,120,250 all sound pretty close.
Tube = tube
Minus the 300b which was made for telephone usage = dull
Heard several tube amps, there are/subtle differences, while others sound completely different. 
@miillercarbon maybe a liner scale lol. On the left is warm romantic, on the right cool neutral?
@russ69 My speakers are DIY Satori MW16P (x2) and TW29R tweeters. 2 way design. 90/91 db efficient, -3db @48hz.
