Part of my problem here is why anyone should be bothered with something they couldnīt hear in the first place. On the contrary, A/B class transistor power amps reach their " good measuring " ( low THD ) by being designed with big amounts of feedback, witch in turn create a " dull " sound becase of TIM distortion amongst other things. You could design around it, but to a much higher cost. Thatīs why a Krell is a Krell and Rotel is, in the end, just a mid - fi Rotel.

(1) This amp has no problems, what so ever, driving any load within itīs designlimits, resistive, capacitive or inductive. This is the point of the concept. If it doesnīt get the power it needs from your wall to do this, it will blow your house fuses in protest. The reason for the variations ( in the ultrasonics ) is the big inductor in the outputstage that protect fex tv sets from the strong ultrasonic noise that all digital amps generate, not the rest of the amp. The dip in the curve is the inductor ( coil ). Driving a complex load doesnīt make it better, but the difference in sound ( and measuring ) to fex a Rotel will be much more obvious with a loudspeakerlike load.

(2) The reason for Azrayan starting this thread was not to make everybody say halleluja for the eARTwo amp ( i hope ). It was for the Outlaws to get their eyes up for this technology. The eARTwo is a niche product for early adopters who want " the best ", but that will not last for long. This is a potential $200 - technology not 10X that. What do you think the eARTwo - guys pay for the modules? $100?...$50?
If interested, anyone can order a $300 ZAPpulse kit from DIY cable.com and get a 200-400-600 W @ 8-4-2 Ohm power amp just by adding ones own trafo, rectifier and caps.
