Well for amps you could check products from Cambridge Audio, NAIM, Myryad, Arcam.
They all have as to say “normal” amps and pretty high end as well.
To my knowledge more or less they have audiophile / hifi grade amps.
The speakers part is much harder since many good ones and all sound different. What it the taste and flavor you like kinda set’s the tone for it.
For speakers i would look from ATC, ProAc, Tannoy, B&W, KEF or Harbeth.
All of them have different types of speakers. Different in looks, build, shape, size and sound.
