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

Trinnov Waveforming technology. 

For the Trinnov Waveforming technology you need the Altitude 16 which is even more expensive than the Amethyst. And you need no less than 4 matching subwoofers. If I go for it I’m looking at the Perlisten D 15s. The total cost will be $42,000.00 not including custom stands for the subs. 
 

It’s a lot of coin. It will depend on how much bass control the room rebuild will give me. We shall see….

“The only drawback is that it that it has a small sweet spot.”

Do you have the head tracking? IMO it is essential. Won’t solve the side by side seating issue but it will free up the narrow sweet spot. Side by side seating is in the works

“ u-BACCH doesn’t have head tracking which is one of the reasons it is a lot less expensive than BACCH. Tell me about side by side seating ?”

If you can, upgrade to get the head tracking. It isn’t just about getting the wider sweet spot, although that’s important, it just works much better. 
 

Edgar has a newer version on the works that will track multiple heads independently. 

“PSI AVAA C214”

I have two of the PSI AVAA C20s. The C214s are definitely on my list of things to try out.
