Guitar amps are designed to produce massive amounts of distortion, and their speakers are terrible from a hi-fi standpoint, meaning that the DSP has a lot of room to add IMD and all sorts of nasty stuff without the listener being able to hear it.I know within the guitar amp world, some solid state amps with software suites have been able to perfectly mimic tube amplification sound and pass double blind tests. So why not with a headphone amp?
Very true, but there are a lot of exceptions to the rest of that statement, except that tube amps are higher maintenance (except nuvistors, but good luck finding an amp that uses them)A high fidelity amp should be transparent, ie amplify the signal without adding or detracting anything else to the signal. A well designed SS or tube amp are both capable to achieving this without any colour or perceptible distortion, providing it is operating within its output and headroom parameters.
He did this for only 2 amps. Mind you, this was 30 years ago, so the quality of the modeling has improved, but so has the quality of the amps being emulated. The signal nulling is just a way to quickly figure out the differences between two amps, not a way to emulate an amp.Carver proved in the 1980s that the sound of any amp can be copied
