Just a comment on speakers.
Their output is dependent on the electronics and room acoustics as well as the sonic expectations. I am familiar with speaker from Wilson, B&W, Focal, Sonus Faber, DynAudio, and many others. They vary somewhat in the general character but are closely clustered on realistic sound. I can assure any perspective buyers that Sonus Faber have absolutely no innate glare, are not thin sounding or heavily colored in themselves, Of course they must be feed an appropriately natural signal with the desire for a natural, realistic, and musical output.
