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

New speakers from Deja Vu Audio delivered two weeks ago.  They are fairly large open baffle speakers with vintage drivers: Jensen 15" woofer, YL Acoustic compression driver and horn, and Electro-Voice horn tweeter.  
@salectric very cool! I listed to a pair of newly completed open baffle custom speakers at Deja Vu about a month ago might they have been yours? If so amazing speakers and if not well any speakers Vu builds are amazing! Enjoy!
Replaced Radio Shack Pro 35 Titanium headphones for portable Walkman cassette player with Grado SR 80 headphones.
