Accurate vs Musical


What is the basis for buying an "accurate" speaker over a "musical" one? I am very familiar with most audiophile jargon but this is one that confuses me. Musical to me means that the speakers convey the "air" or/and overtone of instruments.

"Accurate" on the other hand is what, the accuracy of a single note? If accurate does not convey the space of an instrument, how can it be defined as accurate? I can understand why an "accurate" speaker can be used in a recording studio or as a studio monitor but for casual listening/auditioning?

Thiel is an accurate speaker but Magnepan is more musical so which would truly be more faithful to the original source? Someone please clear this up for me. Thanks.

I spent a couple hours setting up the G68 but there is a lot more there than I can figure out right now. The PLII is much better than before and the Trifield is pretty nice too but there is still too much "energy" or something that makes listening more a chore than a relaxing pleasure. I almost get a head ache thinking about listening. There is a lot of detail that I never heard before it just seems like "too much".

Anyone got any ideas? I don't have any room treatments or eq (I didn't have them before with my lower end but pleasant system), do I need them?
here's another thing to consider.

the issue of musicality and accuracy may be irrelevant to the purpose of listening to music. it may not matter how you describe the performance of a stereo system as long as it satisfies your objective.

i visited a friend the other day and we were listening to the beethoven "kreutzer" sonata. he fell asleep during the last movement.

that is an indication of a great stereo system. sit down, listen and fall asleep, or lower your blood pressure. what difference does it make if the frequency response is restricted or if the stereo systems is low resolution? listening to music is preferable to taking pills.
accurate: input=output. the reproduction of the recording is error free. all stereo systems are inaccurate. there is no perfect reproduction of recordings.

musical: the "sound" of instruments acoustically reproduced.
the sound of an instrument varies with the conditions of the performance venue.

as far as listening to music in the home, musical refers to naturalness of timbre. "It sounds real" is an indication of musicality.

one cannot not know the sound of a recording, so it is not possible to measure the inaccuracy of a stereo system.

in my opinion, accuracy is unattainable, so my focus is the sound of an instrument. i look for adjustments in my stereo system to get closer to the sound of an instrument.
Is Yo-Yo Ma accurate or musical? Some might say both.

He definitely puts me to sleep (in a good way).
It's actually quite straightforward to me.
I would use the term "accurate" as an objective term to describe how well a speaker reproduces the exact waveform as fed to it, without any frequency troughs or peaks or other tonal coloration. Such speakers are sought after as a monitors in recording and movie sound studios, as they allow engineers the best chance to know exactly what is being recorded, rather than a sound any particular listener prefers.

"Musical" is a purely subjective term, and speakers described as such generally color the sound in some way that is pleasing to the ear of certain listeners, and not others.

I recently switched from some older Infinity RS monitors which I'd descibe as pretty accurate, to some B&W's which to my tastes are warmer and richer sounding - to me more "musical".
