combination tube amp and ss preamp?

I thought my philosophy of using a SS preamp with a tube amp was described adequately, but maybe not, so I shall ramble further. There are tube preamps that appeal to me but the balanced dual mono preamp I'm using (Kavent S33) is so good I don't think about it much...my tube power amp simply has a very pleasing 2nd order harmonic slam factor that many SS amps don't have, resulting, for my tastes anyway, in a more involving sound than SS. A preamp's signal is generally at such a low level it should be clean regardless if it's SS or tube so any form of distortion shoudn't be a factor, but the complicated interaction of an amp with speakers is another story and tubes are just more appealing to me. Note how many tubeless SS amps say "tube like" in their hype. I also have tubes in my motorcycle tires due to spoked wheels, and they sound better also.

The problem with mixing a ss pre and tubed amp is input/output impedance... if you find a ratio that works, it is fine... next, over all a tubed amp add much more of the "tube experience" than a tubed pre. If you are after more of the warm tube experience, you would most likely enjoy this combination.

Problem with a tube amp, for a retired HS teacher anyway, is over time you spend more money on tubes than the amp cost.

B&W Diamond speakers have a warm sound already. You probably don't need to enhance the warmness with a tube amp.

Big B&W speakers prefer large high current solid state amp to control the bass and put it in order.

This is just a general understanding but individual taste does dictate choices.

That might take a few years or decades depending on the amp.
