Upgrade with best price/performance ratio


Just wondering what was your upgrade with the best price/performance ration in your audio journey ... like upgrading an IC, preamp etc ...

Let me start:

-Corian pieces leftover from kitchen upgrade project

out of boredom I used the Corian chopping boards and put them in between the shelf's MDF board and BDR cones. The effect was a big surprise ...

- much quieter background, solid bass and cleaned up mid and treble.

Maestro ac outlets...$79 Made my cheap entry level system sound like a much higher priced system !.. far less HIFI sounding to more believable.. more REAL sounding !.. for ONLY $79 !..
The new and improved BOSE 901 series 6 MK2's have the best price/performance ratio that I have ever seen in all the years I have been in this hobby!..
