I certainly won't question the value of your advice, but it's impossible to get a single tool that excels in all domains.I did go on a veer, but my intent was to encourage anyone buying test gear to look down the road and buy the best possible instrument they can afford for the long run.
Ther is a law of diminishing returns. Paying a premium for a voltmeter that goes to 100+kHz does not make much sense in audio. When needing to go to these ultrasionic frequencies, one needs a dedicated votlmeter or a wide band oscilloscope. Same for measuring millivolts of noise.
There's a good reason why there are different types of test equipment.
I don't have any expensive DMM, but I have a complement of one analog meter (you can't replace it for a DMM when you want to view transients or LF oscillations), and a battery-powered oscilloscope, in addition to the standard set of instruments.
