No worries, I like to help.
The TT is Reloop RP7000 MKII Gold Limited Edition.
Regarding the upgrades I can say yes I did hear a difference, but the most is after adding those RED JUPITER 0.1 uF (28 $)capacitors in parallel with the 4.7 uF on the Amplifier signal line(see couple of posts back) > Main SOUND IMPROVMENT.
I had to upgrade some power line capacitors due to aging and that electrolite burnt smell, that the amplifier gave while running. These upgrades were pure functional ones.
Now since you are not into electronics, and cannot do this by your own I suggest to opt for someone who knows, not to do any harm. For now, just plug it and enjoy it. No worries for the rest
