Hey NoDiggity,
Welcome to Audiocircle.
A old friend of mine came to visit me, he happens to be a long-time audiophile too. After listening to my setup, he said:"Your system is doing everything correctly, but something is missing, it's lacking in soul, not musical enough to me."
I don't think your friend congratulated you on your foray into this hobby in a very encouraging manner. For someone just starting out, you've got a system that's a great head start. I would encourage you to not take one person's opinion to heart.
What he might actually be saying is that the sound is very
revealing . In other words, of very high resolution that makes less than perfect recordings sound like just what they are. Less than perfect.
If he were to have told you that you that the system was too bright, or the mid-range was off, or the bass was loose and uncontrolled, or the imaging was off, or soundstage was missing.....these are specific problems that would need to be addressed.
But lacks
musicality , isn't really saying anything specific. It's just his subjective opinion. Without elaborating on any specific issues, it's pretty meaningless. It just means,
he doesn't like it.
If after listening for extended periods, you start to feel fatigued, or annoyed at a certain aspect of your system and feel like you want to turn it down, or off, then you might have a problem.
Don't take it to heart. Just hang out here. It is a great place to learn about equipment. You'll eventually learn to know what the areas, if any, you need to be concerned about.
Just enjoy your new gear, and give it some time, you'll be ok.
BTW, if that's the only negative comment he made, don't make a change, you might have an absolutely great system, and not even know it!

Cheers
