Because the signal from your tubed pre-amp has to travel through quite a few solid state devices in your SS amp, on it's way to your speakers. A typical tubed amp has far less components in it's circuit topography, from input to output, for the signal to travel through. Then, of course, that signal modulates the voltage/current from the amp's power supply through a vacuum rather than of whatever semiconductor(metal-oxide/silicon) your output transistors are made. Some SS amps are designed well enough to allow the signal from a tubed pre to pass unaltered by their signature, but most are not as transparent as a well designed tubed circuit equipped with quality tubes. Now watch the fur fly! =8^)
Question has been asked before but need more info
Ok I have searched the archives including my own posts and I still dont understand the logic behind this concept.
If I have an all tube amplifier and a Solid state amp.
The amps job is simply to amplify the signal from the preamp.
Why would the I lose some of the tube signiture (holographic imaging 3/D etc) moving down the chain?
Why is it necessary to have a tube amp and a tube preamp to achieve this if the only job of the amp is simplly to amplify?
What makes a solid state amplifier warm or cold?
Confused in San Diego
