I’ve been reading about tubes and using them as a pre amp in front of a solid state class ab.
The so-called magic of tubes is partly a result of how they drive speakers. Tube amps have a high output impedance by 1000 times or more compared to solid state. They therefore won't dampen an electrodynamic loudspeaker the way a solid state amp does. Bass will sound more full at certain frequencies but it will be less detailed almost like the box needs more stuffing. Upper mids/low highs will have greater presence. These may be perceived as better by some.
So you will lose that magic with a solid state pre-amp.
