What were your favorite gear additions in 2024?

Morrow Audio SP6 speaker cables. Even in my modest vintage equipment the improvement in clarity is very noticeable. 

Tried, and like very much, the SPL Performer S800

Two changes that brought level up improvements:

Octave Audio Jubilee Preamp. I listened to a lot pf preamps and the Octave was the best to my ears by a significant margin-better everything

Professional room treatments. I was a bit skeptical-thought my room wasn't bad-but this made a big difference.

Shunyata mains distributors - one Everest for the digital side and one Typhon T30 and Denali for the analogue side. It delivered major improvements in dynamics, spatial resolution and that elusive "it sounds real" quality.

Audio Note Speakers -   AN-J SE Hemp Silver model
