Krell FBP c versus FPB cx

Richnus,

The "c" variants added the CAST connection scheme.

The "x" variant is an improvement to the sound quality -
a much "sweeter" Krell - and a move away from the old
Krell "house sound".

I wouldn't say the 300cx IS the old 200c; I would say the
old 200c can be UPGRADED to the 300cx.

That is they share enough components that one can morph
into the other. But they aren't equal in sound.

Dr. Greg, Regarding your 200c to 300cx upgrade comment...that is what I intended to say. I am sorry if I was not clear.

Do you know how much this upgrade costs?

to upgrade to cast is 3000.00 endevor if your not the original owner.
I would probably go cast to start. the difference between the 200c and 300cx was night and day. 300cx is much better in my opinion.

I think the upgrade cost is $1K if you ae the original owner and $2K if second owner. That's what I was quoted for a monoblock upgrade. I bought three 350 CXs instead of upgrading my 250Ms. In general, most upgrades are too expensive and you are better off getting the latest version used on Audiogon.

I am mostly curious about the "C" to "CX" upgrade, financially and the perceived difference in sound. More specifically, the upgrade from the 300c to the 400cx.
