New integrated your thoughts

[Plzzz]

Hi all I thinking of a new integrated amp.
I have four in mind
Musical fidelity m8 xi
Krell k300i
Macintosh ma1200
Simaudio 700i v2
Now normally I go for the weight of an amp but as you can see they all vary in weight so much!
I like speed and bottom end also females vocals my music taste are vary greatly like all of you I suppose.
I want an end game here I want to rest with one of these.
Yes I know I have to listen I done it but impossible all together.
Just after your thoughts.
