I've heard some very good and very bad systems with Krell amps. The common link among the good ones have been use with Martin Logan speakers. I have heard similar sound with MLs using Classe amplifiers. Have also heard Krell amps sound very good similar to ML with Focal speakers.
I've only heard a few bad Krell systems which I would attibute most likely to poor setup/integration and/or specific units not performing up to spec.
I had a Musical Fidelity A3CR for a while. Less heat and bulk I suspect but no resemblance to Krell sound that I could determine.
I might be able to draw some similar comparisons between the Bel Canto ref1000m amps I currently use and the Krells I have heard, but the BCs are Class Ds, and I have never heard a Krell amp in my system, though I have considered Krell as an option.
