the best 'tubey amp - warm,smooth,liquid' ?

i'm using the word 'tube' as the meaning of warm,smooth and liquid sound.
but i could't compare to some tube amps like mcintosh(mc275), cary(cad 805), arc(vs115) and conrad-johnson(premier) at one place and the same time.
some say mcintosh lean, cary weak and not bloom, arc not tubey and cj no clarity.
i need your experiences and advices.
actually i have a difficulty to match speaker systems with.
