There are different models.

I use this one.
Transparent Wing mobile

Time delay lines working between 200-16000Hz Absorption coefficient 0.1- 0.22 (200-16000Hz)
Helmholtz and panel absorber 80-200Hz

I can use them where ever I want to.

It's a Swedish very innovative company.

Tri-amping is in the house!

Thank you Ivan (Masterlu) for the tip. It's a bit crazy. I had a growing idea from early on with The Sonus faber to figure out what may speaker could sound like. It seamed like a waste not to figure it out. Your tip and experience with The Sonus faber and Tri-amping made me do this. I send you the bill... hehe.

For some years I'v been trying to buy Krell FPB amps. It's not that easy. The seller should be trustworhy. That is not always the case. I was tricket quite early in the process. The unit should also be in good condition over all. I also want them to be perfect inside. New capacitors, new contacts and other importand components. They have been thoroughly renovated by an Krell- and HighEnd-expert.
The optimal plan was to use 6xKrell FPB450mcx. After 3 years I got close.
Krell 400cx, Krell 350Mc and krell 450Mcx in perfect condition and renovated.
The latest contender are the Krell FPB 450 Mcx.


This is how it looks...



















This is how it sounds...

8 Ohm, around 1500Watt (due to low specification from Krell it's probably more). per Channel makes these speakers with 7 membranes to excel. 3 amps per channel makes the feed back from the speakers much more easy for the amps.
I'v been Bi-amping for a year and I know how good a big power-headroom is. Tri-ampning is another big step. I didn't know how this would sound, but it's not a small effekt.
The first thing that I noticed was how the midrange, voices and instruments were totally free in the space and almost scary present. The power is effortless, soundstage big and there is just music. Nothing holds back. The gear is not holding the music back.
The power in the bottom end is very deep and textured. Both micro and macro dynamics are very fast and agile.

In my system there has been nothing like this.
One of these amps or my former Gryphon is very good. But this is a completely new level.

The only concern is not a surprise... my fuses. My Nordost QB8 High Currant fuse burns when I play loud. that will be taken care of.

I think the new 450mcx amps has to burn in for at least 100 hours to play at it's best. Already it's great.

Quite the collection of vintage Krell!
Congrats.
Is your wife as enthusiastic as you are?

Thank you.

My wife?
Should I doubt that she is as enthusiastic as I'm? Why? Who does not love a
well sounding High End system?

Haha!
I think you have a very understanding, loving wife.
I do too.
We're lucky bastards!

Carl,
Congratulations - just in time for Christmas and New Years parties. I'm sure your home is the go-to place. That front-on photo is just da' bomb! (Celebrate with a Skåne & Pripps chaser for me over the holidays - all I can get over here is Linjie and sometimes some Aalborg.)

[Antonmb]

Congratulations, that’s an awesome setup.

And yes, Bart and Carl, spousal support and appreciation make the hobby so much more fun.

I just saw this. I am so happy for you. The vintage Krell looks tremendous. It's some of the best gear on the planet. I know tri-amping is the way to go for your Fenice. Your setup is simply stunning. Incredible!

Have you been to the Wilson forum and seen my new plinth for my Thor. It has the Wilson Acoustic Diodes installed. This has taken my extremely low bass to a new level of realism. Soon I hope to experience the new MC 3500 MKII with my XVX. I don't mind waiting because I like to enjoy each improvement before making another one.

This tri-amping you have done is very similar. First one big Krell per ch, then after a while two per ch, then with perseverence and patience the ultimate. I am so happy for you that you have found this vintage Krell gear in perfect condition. Knowing how it sounds, because I live with a stereo FPB 700 for 10 years, I know it is a perfect compliment for your Fenice's. You have one of the very best stereo systems on the planet.

Best

Charles

p.s. I'm listening to "Music for Christmas" James Welch Organ. It has extremely low subsonic bass. You ought to try it with your triamped Fenice.
