Totem Element Metal Version 2 Loudspeaker

They are relatively small for floorstanders. The drivers are good but the cabinets limit their output. What size is your room?

Totem speakers for $18,500 no thank you. 
Look into used Wilson Sasha 2, some Magico models, Rockport. If you want Totem, the Wind is where they max out as far as I’m concerned. 

I am seeking a speaker with more slam and dynamics. 

You’d be hard pressed to do better than these SCM50 towers if that’s what you’re looking for, and they’re fantastic all-around speakers.  They require power to fully do what they do, but your Bryston should be up to the task.  Best of luck.

The new Totem speakers punch way above their size, same as Raidho and Borreson. Not sure if these Totem speakers are worth $18k. I’ve had many Totem speakers in the past and I thought the Mani 2’s that I had sounded better than the Winds, this was 20 years ago. Plus I’m not sure if you Bryston amp would be a good fit, they might be too cool sounding for the Totem tweeter.

You never stated your room size so I’m going to recommend decent size speakers for a medium size room that will sound much better than the totems for 1/2 the cost:

Revel studio 2’s, revel salon 2’s used, revel f226be/f228be/f328be new depending on room size.

Usher be10/be20/x-towers depending on room size new or used with the dmd tweeter.

When I was looking at new speakers, out of all the RMAF rooms, I narrowed my search down to 3 speakers: Usher be10/x-towers at $15k, Revel at $20k+ or the Raidho D4’s at $110k. My wife told me it was my choice so we went back and forth between the 2 rooms many times during the show listening to the Revel and Raidho, we already heard the Ushers at the previous rmaf show and at a dealer. Ended up buying the Usher x-towers, and this year bought Revel.
