@hgeifman FWIW, class D amps vary in sound more than tube amps seem to. So having a bad experience with one isn't an indication that another will be the same thing. The Hypex and Purifi modules are sold as parts so you have to come up with a power supply and input buffer, which has a dramatic effect on how they sound. At this point IMO its pretty well demonstrated that some of those modules have been put in boxes by by people that don't know what they are doing.
