What is meant exactly by the description 'more musical'?

Everything in audio is of course subjective because we are all a bit different. I bave Plinius amplification in two systems. I have tried many different amplifiers but I do not get the full rounded sound from other amps as compared to my Plinius. They maybe good amps with great detail and sound stage but to me they lack the full rounded balance of sound that I get with Plinius gear. what I mean is that across the frequency spectrum they are very balanced and full sounding. Perhaps slightly warm but detailed as well. Thatvto me is musicality.

When a amp is not harsh and bright, tonally balanced and your sound is smooth with treble and bass. Some amps can have a strong bass oitput and become very punchy. For me the some Yamaha amps are very musical, while others can be bright.  My Luxman 590 is very detailed and the music is refined to hearing the clean crisp sound.  Its a matter of taste and preference,  i have Yamaha, Luxman, NAD and Emotiva EQ.  You tell me.

@webking185 wow, I think it’s cool that you have that collection. To me, my Yamaha setup is a bit more detailed because it has more of a holographic stage than my Luxman 595.

I love my Yamaha setup which is a r n2000a used as a preamp to a AS-3200. I never thought Yamaha would be this good. I plan on buying a Macintosh 12000. It might break my heart if I use it more than the Yamaha cuz the Yamaha is so good.... I am emotionally attached.

Fine. I'll follow this discussion. 

It's a subjective descriptor. It means that the whole of the component's sound conveys music in a way that pleases. Or a way that conveys the emotional content of the music. It's the most important descriptor. It is my bottom line when evaluating a component.
