Solid state power + tube pre or visa versa?


Over the decades I've run solid state preamps with tube power amps and the other way around without being able to say which combination is necessarily always going to be better. I'm about to replace an entire system lost on a flood and find myself wondering at a recommendation that the combination of solid state preamp with tube power amp is ALWAYS better. Wanting to reduce my shortlist of potential amps I wonder if anyone has has a theory as to why these claims are made, a scientific one that is.
At the moment my short list is headed by the same Leban preamp I lost with a pair of bi-amped solid state power amps. Any thoughts?
Speakers are yet to be considered - I know - I should audition them first then choose amplification . All I know for sure is they WONT be horn loaded and highly efficient. Something like the top KEF's reference series maybe.

Speakers really drive the decision as to what type of amp to use. Power ratings, impedance, etc. and, efficiency of the speakers. The room size and layout also affect the decision on amp.

I have heard excellent solid state pre-amps to tube amps driving fairly efficient speakers. I have also heard excellent tube pre-amp driving tube and solid state amps.

Just remember that when you are auditioning speakers in the store, you are also auditioning the amp/pre-amp combination also. So, be prepared to request the store salesperson to swap amps and pre-amps with that set of speakers.

Have at least two different amps of the correct power ratings and impedance characteristics available with the speakers.

This would also be a great opportunity to listen to a solid state power amp and tube power amp with the specific speakers to be auditioned. Just to hear the differences.

For example, I would want to audition a particular set of speakers at a store and say for example they also carry Mark Levinson and Audio Research equipment or Atmosphere equipment.

You can then swap the amps (ss vs tube) with a particular pre-amp to hear the differences on the specific speakers.

So, room size, listening position from the speakers and really important, my price point for the speakers will determine what speakers I can afford and which ones I really like first.

Then, what amps can specifically correctly and accurately drive those speakers. Taking into account what the speaker manufacturer recommends also. Solid state and tube.

Then, audition pre-amps with the speaker/amp combination.

I haven't even started on cables and power conditioners, etc.

But, decide on the speakers first (if you are starting from scratch), and work backwards from there.

I hear more detail with my tubed pre-amp and solid state amp on the upper panels of my Martin Logan Monolith III Speakers. However, the Audio Research REF 250's just sound soooo good that I use the Mark Levinson on the base drivers and the AR REF 250's on the upper panels, with a AR REF 3 tube preamp.

Very hard speakers to drive, but tube pre-amp and tube/solid state amp combination works well for me.
