You have purchased a lot of great equipment. I would relax and be excited at the prospect of having a great system. I’d like to point out that Pass Labs amp is an incredibly good piece of equipment… that I would say is as middle of the road audiophile as you can get. It has a great tonal balance, not tipped towards really warm or fatiguingly detailed… has excellent musicality (makes you tap you foot and emotionally be involved with the music), and lots of power.
I could go on… all good stuff.
I think your reaction will largely depend on your history with high end audio. If you have none or a very small amount, you are likely to be simply overwhelmed. So, if you will be comparing this with a inexpensive audio / video processor… it’s going to sound great. I think this is where what you don’t know works to your benefit.
So, if I were you. I would set it up and enjoy. As has been pointed out… you have all great components. It will take at least 200 - 500 hours to break in. You want to learn the nuances of the sound. Remember don’t judge until at least +200 hours.
Read about speaker placement and room treatments in the first months. These make a huge difference in sound quality.
This becomes your reference system. After a long time you can venture out and hear other systems and see if you think some difference in character of the sound is worth pursuing… probably the speakers.
