Do the free stuff first. Set up the system properly.in your room. Location of speakers are equipment makes a big difference.
Speaker are no more important than anything else in the system. They should be the last thing replaced. The most important link is your source. Whatever gets the music off the media is priority. Speakers will never add back what was lost at the source.
Priorities should go:\
1) Cartridge
2) Arm
3) Turntable
4) Phono stage
5) Preamp
6) Amp
7) Speakers
always buy the best cables you can afford or justify. Don't waste money on highend speakers when the rest of your gear is not up to that standard. Garbage in garbage out.
