Just read the bad experience I had with the NCORE (Hypex) amps with the built-in input stage. You’ve mentioned for years, the input stage feeding the Class D Amps is critical to the sound of the amp. Be it FET or Tube based. Ya, one could tame a Factory Class D Amp module with DSP EQ if your feeding normal Speakers or like I have in my rig by replacing the Bose Analog EQ’s with MiniDSP’s. But I agree, an “Analog Cell” is what make the M700’s/S300 (to replace the borrowed NCORE’s) so special.
