If we limit this to sound quality I will answer.
Back in the late 1980s I did a day's auditioning with a friend. Between us we had a lot of mainly Audio Research and Krell gear - one all valve, the other solid state.
We consistently found that valve pre-amps with transistor power amps did the business. Krell pre-amps were notably grainy. But Musical Fidelity's first product 'The Preamp' was SS and gave an SP10 a run for its (much much greater) money.
I have remembered that ever since and have stuck to tube front-end and SS power. Mainly AR and for nearly 40 years Krell KRS200. Oe recent deviation has been The Grail, the SS phono amp from vdHul, which sounds wonderful to my ears.
