What was the best (most impactful) piece of new equipment to hit the market in 2023?

@vinylvalet 

What external power supply have you stumbled upon?

I am hoping the Weis 204 is a simple transcendent DAC for my system. 

Most of the expensive linear power supplies sold in the states are Chinese rebranded or in a fancy case with greatly elevated prices. I've seen exact units sold for five times more in the US.

All of these power supply types have an internal trim pot that let's you adjust the voltage anywhere within the specified range.

Ultra-low noise Linear power supply DC 5V/9V/12V/15V/18V/19V

@deep_333 BACCH has been around for awhile but u- BACCH was introduced this year. I purchased it at the introductory price.

@scottwheel thanks for the update. Head tracking for two listeners would be great especially if it would work with Windows.

+1. I think it hit the market a couple years ago but hit my system in 2023 ….. Grimm MU1. 

The Primaluna Evo 100 phono is the most important upgrade I've made to my system in a long time and by far the best phono preamp I've owned, tube or solid state. It is the only one I've heard that does not sound harsh with massed strings. The way it portrays instrument position in the soundstage and natural timbre and realism, while sounding hugely dynamic and fast, is unmatched in my experience. I could go on and on, but I will say that it's all tube design is now a requirement for a phono preamp for me. And this is with the stock tubes. I would put it up against $20K+ competition.
