My guess is that most of us are "hard to buy for". That said, I get my own presents.
Outside of audio, this holiday season I treated myself to a 3D printer (Bambu Lab P1S), a ZWO Seestar S50 smart telescope, and I will be ordering a PiFinder for my 20" telescope next week.
In the world of audio I upgraded my Rogue Cronus Magnum II to the III. I added the home theater feature so I can put a tube pre-amp between my DAC and the amp at a later date. And since they had the amp in the shop I added a processor loop in the event my hearing would benefit from additional processing in years to come. I'm a small spender for this group and I expect this is my ultimate amp. I will upgrade other components over time, but this is making me very happy right now. Besides, my astronomy hobby is where most of my extra money goes.
I've been playing the CR III for the past week and it is an amazing upgrade. It also helps that my backup amp was a major step down and since I hand delivered and picked up the amp I've been without the CM since October.
As far as the new amp goes, I love the triode mode and the phono pre-amp is noticeably improved. I'll test out the new headphone circuit in January, I don't use headphones often so I won't be able to weigh in on any improvement, just the end result.
So, what did you get for yourself?
