Chadeffect and Stevepancevo, there is no free lunch when buying any amp genre. Class D is no exception. The ICE modules married to digital power supplies were not created for high fidelity purposes. They were made for mass production purposes. Builders making pretty box amps have come and gone, their products disappointing.
The 500A module, on the other hand, was made for better amps. It requires an outside power supply. B&O's engineers spent umpteen hours improving that module, despite constricted sales.
Any success with the 500A module depends on the user's engineering prowess. Here is where Henry Ho shows his supremacy IMO. Along with his Fire preamp, this duo kicks ass on my Scintillas. I have Tyco drums on now...... egads!!!!!
