Anyone heard of Jam-Tech True Fidelity Amplifier?
I stumbled across this website reading Audiocircle. It is a company called Jam-Tech, who created low power open loop Class D amplifiers.
Their specs are nothing special, but there was a triangle wave test done at 22hz which says:
To see the actual dynamic range, try a simple linearity test. To confirm an amplifier's true dynamic range, try feeding the device a low frequency, low amplitude triangle waveform. This is an excellent indicator of amplfier response, as well as offset. Center the signal on "zero" and watch the fun!
I haven't seen any other manufacturer perform a triangle wave test for linearity. Does this test prove anything, and what is it's real relevance?
