The newer Krell FPB x-series are the most musical amps they have ever made. Some people like the older KSA series, but I have spent hundreds or thousands of hours listening to both, and none of the older amps are as musical as the newest amps. Depending on how much money you have to spend the FPB 400cx is a good choice, if you have the money the FPB 700cx will dominate a big speaker like the B&W's, and let you hear what they can do with the right amps.
Best used Krell two channel amp?
For those of us who are just now looking at upgrading, there is a dizzying array of Krell amps to choose from. In your opinion, what second hand Krell would you recommend as being dependable and affordable. I would like transparency and effortless power to run my big B&W's. Thanks, Jim
