WHY VACUUM TUBES
The output level of studio microphones under typical recording conditions
contain peaks far in excess of what VU meters display. Everyone knows that,
but the peaks, as measured with an oscilloscope, are really quite high, easily
exceeding 1 volt! The tube or transistor used in a condenser microphone, or in
a microphone preamplifier, often will be driven into severe overload by these
peaks. The peaks are short, so the sound isn't grossly distorted-sounding; but
the distorted peaks do affect what we hear. All preamps (and condenser
microphone electronics) are overloaded by these peaks, but tubes handle it
differently than solid-state devices. When transistors overload (in a discrete
circuit or in an OP amp), the dominant distortion product is the third
harmonic. The third harmonic "produces a sound many musicians refer to as
blanketed”. Instead of making the tone fuller, a strong third actually makes
the tone thin and hard. On the other hand, with tubes (particularly triodes)
the dominant distortion product is the second harmonic: “Musically, the
second is an octave above the fundamental and is almost inaudible, yet it
adds body to the sound, making it fuller”.
Tubes sound better because their distortion products are more musical. Tubes
provide a more appropriate load to transducers. These are the fundamental
reasons why tubes simply sound better.
