Again, neither of those are digital. The "D" in "Class-D" doesn't stand for Digital. In fact, it doesn't stand for anything at all!then I must try a pure digital amp like a mark bass or Peavey megabass 1000

For audio? There aren't any, at least not from front end to speakers.then what's a digital amp.. and I'll be glad to try it..
Heard that a lower watt tube head can be just as powerful as a SS head at a much higher wattage. How would 300 tube watts compare to 1000 solid state watts?
because the difference in voltage? 110v to 220v.Please remember that British watts are louder than any other watts.
FACT!
then we have a whole other thing with Digital-SS-tube preamp to be included. in this.

Neither of those amps are digital either.
The switching function of a class D amplifier is binary. Most people would, therefore, refer to it as a digital amp.
You are correct that the output wave-form is always analog.
A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers. The signal to be amplified is a train of constant amplitude pulses, so the active devices switch rapidly back and forth between a fully conductive and nonconductive state.
The analog signal to be amplified is converted to a series of pulses by pulse width modulation, pulse density modulationor other method before being applied to the amplifier. After amplification, the output pulse train can be converted back to an analog signal by passing through a passive low pass filter consisting of inductors and capacitors.

It is analog at all times. There is never a digital transformation. Therefore it is never digital.

Most people would call a binary (only "on" or only "off") switching system as a digital system.
A class D "amp" goes from completely off to completely on by following a train of pulsing signals. The output of this switch is not analog, but is a series of binary pulses. This binary chain is smoothed out via filters to make an analog wave.
The conversion of the analog input signal to a series of pulses is an Analog-to-Digital conversion. The signal driving the amp is binary and the output of the amp (before hitting the filter section) is binary. Most people would refer to this as a "digital amp" and they would not be incorrect.
