if you had this system, what would you do to make it sound the best you can

I concur with audphile post above ...😊

it is ridiculous to advise about a piece of gear isolated in a system and in a room we dont know...

The only wise recommendation is not to upgrade but to try to improve what you had studying the mechanical, electrical and acoustical aspects BEFORE upgrading the right piece ...

Add to that that all these gear focussed people will recommend all different pieces of gear to upgrade ...😁

Acoustic rule audio experience not the upgrade which must be done only when we know how,when and why to do it...

can anyone actually tell without listening to your system what needs to improve?

all we can do is guess. Are you going to take action on any of the above recommendations? Even that equalizer…I’m pretty sure you like it and that’s why it lives there.

You don’t even mention what you would like to improve on. I’ll be blunt…this is a BS thread.

I concur with

Riccitone advised you well...

upgrading is not recommended as a first move if your system is already synergetical...

To go for more learn about your electrical grid, the control of vibration on your system and room acoustic...

Upgrading will give you no knowledge at all save if some gear piece is too much sub par to the other piece ...

You must learn with what you have and then after exploring the way to use optimally what you had already then you will know what piece3 to upgrade and why ...

The most fun part of this hobby is the journey in experimenting with what you have already ...

upgrading will never be so gratifying than creativity...

Upgrade is useful when we know why with what and how to install it rightfully in a room with the other pieces...

Takes your time read a bit and think with simple experiments to begin ...
