Some valve preamps sound amazing and valvey, some sound amazing but not in a valvey way, and some sound mediocre. Just like generalising on tone based on speaker diameter leads you to often incorrect conclusions, so does generalising based on amp topology.

Fully agree. I have a number of preamps myself, such as a Glockenklang that is completely solid state and a Hevos that containes two valves. The differences between these preamps are very subtle.
