When and what was your last significant equipment upgrade?


I will start- December 2015, a DAC (Bricasti M1)

As I've said in the past, I truly believe I am done in terms of buying gear, but more recently I finally merged my laptop with my DAC to explore hi-rez audio, which I am enjoying a great deal

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!

A Balanced Power Technologies 2.5 Signature Edition. This unit really rounds out my system. Now if I could just build that dedicated room....
Townshend Audio speaker bars. I never could have thought the fantastic results on my plannar system. These things are incredible and at very reasonnable price.
Purchased an Ayre K-1xe preamp yesterday to replace the Modwright LS-100 that I can't seem to find quiet tubes for.  Hopefully finished upgrading now.
