Someone recommend me a studio Reference Amplifier

as above ^^^ just need an amp with the 20hz - 50hz range around 100 to 150 watts per channel. just got some new monitors and need a amp now was going to use my Kenwood until i had the spare cash but just notice that the fishing thing rolls off a 80hz so i end up with a sound with no balls lol

also can i plug my sound card into a reference amp or do i need anything in between the two

Return them and get monitors with amplifiers included.

i don’t want to do that as all the active monitors i’ve ever had cost an absolute fortune if anything goes wrong and you need to fix them.
