New speakers for $5000

In your system profile you have those Harbeths! What's up with that?

I plan to upgrade the Harbeths as they are many generations old.  Perhaps I should have been clearer in my post.

I recommend comparing and contrasting the sonic characteristics in an AI.

Here’s a summary from one:

• Choose Harbeth C7ES-3 XD if you want: long, relaxed sessions; voices that melt you; forgiving treble; you listen nearfield or medium rooms; you favor acoustic/organic music.
• Choose Totem Forest if you want: more bass authority and drive; toe-tapping PRaT; laser imaging; higher SPL capability; you play a lot of rock/electronic and want excitement.

With Rel introducing a new series of subs.  A second s812 is going to have a bigger impact on the game show than any other upgrade in my opinion.

this was one of many I saw on Google

After you get the subwoofers settled, I would consider spending just a little bit more than five grand on my new speakers. Looks like you are doing an awfully nice job of building a system. Starting to get into big boy territory and you’re gonna wanna represent. hope some of this makes sense. Good luck! 🍀 🎲. 

What about GR research (Danny)?
