Best Loudspeakers for Rich Timbre?


I realise that the music industry seems to care less and less about timbre, see

But for me, without timbre music reproduction can be compared to food which lacks flavour or a modern movie with washed out colours. Occasionally interesting, but rarely engaging.

So my question is, what are your loudspeaker candidates if you are looking for a 'Technicolor' sound?

I know many use tube amps solely for this aim, but perhaps they are a subject deserving an entirely separate discussion.

different instruments will their produce their signature timbre at different frequencies. Is this not correct?

It seems to me that one should look to acquire speakers with the most accurate response over the widest frequency range.

If I am imagining right what you have on your mind, Sonus Faber would fall into that category.
I don't have a specific recommendation but I do think that the OP wants very high performance level. And the rest of the system, including recordings, should be up to this as well. $50k set-up for a medium size room ? At least.
Why spend the dollars on a speaker when one can saturate and distort, delay, pitch shift, play with reverb, EQ, etc. to fatten up portions of a recording?
