What’s your latest high-end audio purchase?

Canary Audio preamp, and I have to say I really love it.

"high-end audio"? Define your term ;-) . A plain ol' audio purchase isn't good enough? I don't like the term audio anyway, it's too general. Hi-fi has more meaning, in terms of the reproduction of music, a very specific thing. 

Netgear Broadcom chip based modem, replaced Arris Intel chip modem, also has external power supply vs internal with Arris, allows use of linear power supply. Intel chip modems have much higher jitter.  Substantial improvement in sense of ease relaxation, especially in consideration of relatively low cost of modem and lps.

The other recent purchase was Duelund CAST PIO tinned copper caps replacing Audyn True Copper Max in custom build 300B monoblocks, the CAST PIO relegates all other audiophile caps I've used to distant second place.
