Krell FPB-300 vs FPB-300c ??

With the 400, there was more done to the amp than just the addition of the cast.
The sound is better, but how much is very debatable.

I have elected to stay with the 300 and take advantage of an aftermarket PC, which you can't do with the 400 without voiding the warrantee. Probably the best sonic result would be from an altered 400 with an aftermarket PC.

So what's the difference between 300c and 300cx??

The "c" is an FPB 300 with CAST inputs The "cx" is what used to be a 200c but the new technology that Krell has developed allows 100 more watts per channel from their amps. Their smallest class A amp is now the 300cx. What was their 300 watt amp is now 400 watts. The 600c is now a 700cx. Owners of earlier models can have them updated and gain 100 watts per channel. Owners of earlier designs that have removable power cords can have their cake and eat it to by upgrading.

Wow. 300c does sound like a sweet one to get !!! I am glad I didn't jump on a 300cx; not that it is not good but the fact that it's 200 design didn't quite entice me.

Rwwear is correct. Other than the 'cast' technology and the faceplate design, there was no difference between the fpb 300 and the 300c models. The cx upgrade, however, IS different. I own the upgraded 300cx. Sonically, the Krell cx models are more open sounding and less 'dark' than the earlier fpb's. And, if you want to be 'enticed', then you should definitely buy the 700cx. If you just want great sound, then match the size amp to the size room and speakers you have.
