You should ask Harman Kardon for that. I believe they said live music could go beyond human hearing limit, they didn't say to 100,000 hz.
Sorry, when you said "to reproduce that" I took that to mean 100KHz. I know the Blue Hawaii is 3 dB down at 400KHz according to KG's website if that interests anybody.
You can measure the frequency response (in Hertz) of an audio component like an amp. Different amps have different frequency responses. It is common for people to quote how 'far' the amp can go on both ends of the spectrum before tapering off a certain number of decibals. 3 dB is a very common figure to use there, as it is in many audio applications (I believe it is percieved by the ear as being a multiple - 'twice as loud' - though that may be 6dB, I can't remember right now). What can be taken from that measurement is that the amp is flat from DC to 400,000Hz. Some amps don't measure as flat, being 3 dB down within the audible spectrum (generally taken as 20-20,000 Hz) isn't even that uncommon.
20Hz-100kHz?This thread has the widest response of any thread I've ever read.
Could amplifiers reach 100,000 hz ? My old Harmon Kardon amplifier had such claim. Live music goes beyond human hearing limit and to reproduce that would give similar "live" feeling.
