unbeatable Class A integrated

Thank you all! I'm learning a lot and I ask myself new questions ... Maybe with that budget I could give up the integrated one, and bet on AMP + PRE.
A First Watt amplifier (or some SIT1 if I find them used), some Valvet A4 MKII monoblocks (5K in Europe) and a good preamp.
What do you think?

Thank you, I’m learning a lot!

Is there any of these SS amps that sounds close to a 2a3 tube amp?
I have a small room, high sensitive speakers and I like low volume.
The tubes are banned until my daughter grows up. :___)
