What’s your latest high-end audio purchase?

Morrow Audio interconnect cables. Huge difference from what I had.
 

And 3 wks before that well most of my new setup - Focal Aria 926 & Rogue Audio Sphinx V3. Love the setup! 

I replaced my Wyetech Labs Jade preamp which had served me well and sounded great for the last 15 years with a Bankert Labs Rhumba 1.3 Extreme. That changed the sound of my system to a more detailed and faster one. The extra gain from the 1.3 brought new life to my ZMA, Wyetech Topaz SET and PASS Labs XL 30.8.

Lindemann Limetree Bridge replaced my Sonore Micro Rendu, much more stable and reliable certainly no loss in sound quality probably better. The mR seemed to particularly dislike my Denifrips Ares ii, another fairly recent purchase I am exceptionally pleased with.

Bought a used Rane GE215 graphic equalizer (2 channels @ 15 bands per channel) for $65 on eBay for room equalization.  More a "pro" item than "high end," but it works good and I am happy with it.

Congratulations on the AT33Sa! My last cartridge purchase was its mono sister, the AT33MONO (50th anniversary edition). It also sounded thin in the beginning, and then the body came out. Went through the biggest transformation during the first 25 hours, but kept steadily improving for hundreds of hours.

The best thing with it is that it can keep up with component changes extremely well. Upgrading phono stage, turntable - and it will keep up with it at an astonishing degree, given their relatively modest prices.

Have fun! ;
