Extended HF response can be a real problem in audio gear, when they start picking up and passing RF, and worse, sometimes oscillating via the “antennas”. But there were lab uses for this kind of stuff.

McIntosh amps all went as high as 50 kHz out and some as high as 100 kHz. A lot of them were used to relay baseband telemetry and more recently to test notebook display backlights (see the late Jim WIlliams’ books).
