Recommendations for an Amp/Preamp combo excellent musically and very reliable

Hello, having often encountered major reliability problems with components that may be too sophisticated in their design and which have taken too many months to be repaired, I thank you for giving me your recommendations for an Amp/Preamp combo that is excellent musically and also solid as a rock. My speakers are Magnepan 3.7i with 2 Vandersteen subwoofers.. My room is 550ft2.  I am looking for a holographic placement of voices and instruments, a 3D soundstage. I want a sound that gives me goosebumps. I do not want the bass to be sloppy. I am looking for a sound that is not tiring after a few hours of listening. My musical styles are very varied from classical music to jazz, pop, world music, rock, blues, rap, hip-hop...Budget is up to $15k and I could consider used equipment. Thank you.
