What were your favorite gear additions in 2024?

PS Audio BHK signature preamp. I continue to be amazed at the improvements this quality preamp brought to my system. 

Revel F206

A Music Reference RM-5 Mk. IV, the final iteration of Roger Modjeski's phono and line stage pre-amp. I don't really need it, but thought it would be cool to have a complete Music Reference electronic chain (I own his RM-9, RM-10, and RM-200 power amps).

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
