Krell FPB and cast versions

I had a pair of Thiels CS 2.3s and Krell KAV300i(Some people don't consider this a real Krell).

Chazzbo hit it right on the head, its bright and metallic all the way! I could barely listen to it for more than 30 minutes at a time.

DH,

I have own Krell combos with the Thiels 3.6 and the CS7’s.
The only difference as you have mentioned between the Krell FPB and the Cast are the protocols between the connection. If you don’t have the cast chain then stick with the FPB. The FPB300 will be a nice combo for sure.
I was using a Hovland pre and moved up to a solid state from there with a 600cx now.
You won’t go wrong with the combo. Cables and setups are the major issues with making these things bright and brittle like many say about Krell. My Krell setup now is actually smoother sound that my ARC PRE POWER combo with all the control and resolution I can ask for. Go with some neutral sounding cables and they will work like a charm, Transparent Audio, Clarity Cable and so on…. Avoid the Synergistics Research and others that fall onto the other spectrum of preference.

In your case do try some tube preamps if you are concern by all means making sure their output levels match between one another so that you will acquire sufficient gain for the system.

Krell/Thiel IS NOT BRIGHT!!!

Chazbo what you smokin'? ;-)

Wrong plain wrong.

And 300i powering 2.3s, well duh, of course!

Where the heck does this stuff come from?

Thiels are revealing but the 7 series is not that "bright" Chazzbo. Krell is a great match for them.
