When and what was your last significant equipment upgrade?

I am 3 weeks into listening/breaking in my new Vandersteen Treo CTs.  I traded in my Vandy model 3s which I owned for 22 years.  The musical truth the Treos reveal was beyond my imagining.  Richard Vandersteen does it again!

Bought one 1 meter AQ Colorado RCA interconnect and two .5 meter ones on the Music Direct half price sale.  This is the third day of around the clock break-in, much of it with Purist Audio Designs System Enhancer Disc and I have never had a clearer window to the music.  It makes other cables sound "confused"  Ridiculously great value at such close-out prices.

@gshepardbuster  Can you elaborate on the differences between the P5 and P10?  I am on my second PS unit.  I went from a P500 to a Premier.  

@jond  "patience is a virtue"  7-10 weeks?  You sir, must be virtuous indeed!
