Why some preamps does not play music? Cold?


I mean technically/electronically wise, why some preamps while been very revealing and very good in reproduction of frequencies and extensions, are at the same time not engaging musically and emotionally and even boring? Are there a solutions to fix that (except for changing preamp)?

No, they are tube. BTW, in that respect i'm talking about it does not matter tube or SS, but i had in mind tube pre.
"Slow"... Hm... It is interesting... I’d say might be not exactly "slow", because it might have swing at the same time, but most likely wrong PRAT, that screws original melody, therefore depending on music played it varies from "Ok" to "bad". Hm.. Yep, thats probably it. In this case i guess there is no fix for that except for new preamp.(((
