Yes, sometimes there is additional circuitry to Icepower modules. For instance my small Rowland has additional instrumentation amp (THAT1200), that improves common mode noise rejection as well as increases standard 10k input impedance to 40k. Box is pretty indeed, but since it is solid billet aluminum chassis - board inside is acoustic resonance free. There is a purpose to that - but when manufacturer puts Mosfet stage in a plastic blue box, calls it fancy name "Analog Cell", describes it as class A with no feedback and inserts picture of the board with this blue module in their literature - then it makes me very suspicious. Not only that using "class A" is to pray on non-technical people, but also second statement is not true. There is practically no stage without feedback. Even resistor in the emitter (or source) of transistor is a form of the negative feedback. First stage might be outside of the global negative feedback, but calling it "no feedback" is again praying on the common believe that "no feedback" is a good thing.
Because of all that I'm very suspicious about additional Mosfet stage used for the "voicing". We also have to assume, that B&O engineers, that are fanatic about sound, and Jeff Rowland neglected to properly "voice" it. Would people buy this amp, after finding in the sales literature, that the company just packaged inside standard inexpensive Icepower modules? Most likely not and that's whole reason for the "puffing".
