where best to spend $2-3000 upgrade dollars in my system


Looking for help/opinions on where to best spend upgrade dollars in my system and recommendations.

Here's my current set up:

Musical Fidelity A300CR dual mono power amp

Musical Fidelity A3.2CR dual mono preamp

Musical Fidelity A5 CD Player

Kyocera T910 digital tuner

VPI Aries Scout with Dynavector MC 2x20 cart

Klipsch Cornwall II speakers

Also using Monster Cable Z2 Reference speaker cable, Cardas micro-twin phono cable, Van Den Hul D102MKIII cable for CD, and KimberKable PBJ for the rest

Lastly, using Furman Elite 15DMi line filter/power conditioner

Look forward to hearing ideas, thanks

I don't know what I necessarily want to achieve. Always thinking that I might want speakers that excel and low listening levels.

That's strange, because that is one of the strengths of efficient horns like the Cornwalls.
Having owned Cornwalls twice in my audio journey, I agree that they like to be played at more realistic (live) levels, where they really come to life.
So many variables to take into account before any change. For instance, How large is your room? How close do you sit to your speakers? Concerns of noise transmission to other living spaces? Type of music most often played? ETC.
Room and speakers and the interplay between the two are THE most important aspect in an audio system. 
As has been mentioned, have you any acoustical treatments in your room?
Always a good place to start.

I would be willing to try power cords but honestly imo, when I added the Furman line conditioner, it added a richness and depth to the sound that wasn't there before. I live in the city and are power is known for not being clean.

Power cord suggestions?

@mattmiller 

thanks for the suggestions on cables. I do know cables can make a big difference.

I do not feel like my system is broke at all but always interested in tweaks and upgrades which may be that "bit of magic".

I'm going to look at room treatments.

for the room questions/comments, my listening room is 12x12, laminate floors with a large rug in the middle, wood paneled walls, plaster 9' ceiling.
