replace cd player and computer speakers

m 40 audio speakers (the old ones) have the amp inside. The volume control is noisy.
Vanatoo was good at nyc audio show as was the voxativ.I didn't notice room problems.
as for budget, i want the improvements in the source to be audible at a level to justify the increased cost.The room is small.i can't blast out the JBL pros or MBL's i will upgrade the tt ,also from an old technics sl 10 (which is also no longer viable; too much record intertrack noise/can't adjust the tracking above the alleged indicated1.5 gms)...........

thank you
it took over 30 years for many of my interests to  appear on cd from the bootleg days in the 70's and they are only now being available on steaming in a quality resolution.
the first step is to seperate the upper  bass from the lower midrange to clear out the haze and provide more detail and forward motion.

and phono section/tt/cartridge ?: that does not exaggerate intraband  surface noise and has good tracking performance? .
