I have always wondered if anyone had made a DIY amp that performs in the same way as the MF Supercharger or if there are any schematics out there. I can't seem to find any.
"The Supercharger 550K uses the latest in low distortion circuitry in a bridged configuration which delivers 550 watts rms. The Supercharger 550K is designed to increase the dynamic range of an existing lower powered amplifier (from 50 watts to 200 watts) to 550 watts. The dynamic range will increase by up to 10dB."

I assume (but may be completely wrong) that the OUTs from your "existing" amplifier go IN to the supercharger which uses some kind of Hi-Level to RCA converter circuitry to accept the hi-level input.
If it is that easy I am surprised that it has not been more commonplace or is it that you may end up with a result that is a dogs dinner?

Strange concept. Not sure what the benefit is over a line level balanced (power) amp. All the cost is in the output stage and PSU so no real cost benefit. I guess if you had already invested in a nice integrated amp it saves you having to buy a pre-amp?
It has a line level input as well so they have just added an L pad to connect to existing integrated amps. At least it would (probably) make them run in class A. Another bell or whistle from marketing? I get the low gain thing from a DIY perspective. Always felt the pre-amp should do more work. 🙂
