Transformer coupled / Capacitor coupled

Just a question from my curiosity. I remember someone recently mentioned here that capacitor coupled pre-amp sounds better and is more expensive and rare, than transformer coupled ones. Could someone elaborate, as to the difference of those two and how each design works and why either sounds better? Thank you!

Peter, what would you say on passive transformer-coupled preamp? Is it possible?

Did you also research Manley 300B preamp? I'm not sure about coupling transformers but it definitely used power output tubes. I was stupid not to ask EveAnna if they can include an option to use it as SET integrated.

You could not do transformer passive. That is impossible by the very nature in how it works. There are many tube pre-amps but most only use capacitor coupling. This makes impedance matching to the amplifier Sorry

Here is a discussion of a transformer based "pre" by Thorsten Loesch. Heard it in Chicago a few weeks ago but was not able to draw any conclusions.

Interesting article. Learn something new every day. Unless I'm reading this wrong you still have some impedance issues. Is this correct?
