Bought a system without auditioning, thoughts?

Don’t overthink or obsess.

Set up and connect the system. Stable support for the electronics.  Do some reading about the Forte IV and take your time to decide the positioning for best sound. Enjoy your favorite music.  Hopefully, it sounds great to you and you are all set.

If, after spending some time with the system you want a change, then different speakers would probably make the most difference.  Fortunately, the Pass allows you to use speakers with a fairly wide range of efficiencies.

you have the ability to try less .

Looks good to me and would suit my taste... If klipsch too much warmth but you like presentation then trying a JBL studio monitors might bring similarities but a slightly clearer presentation whilst not being analytical or sterile. 

@OP If you had to buy a system unheard (which I don't recommend doing), that's not a bad shot at it. The speakers wouldn't be my cup of tea but at least the Pass amplification is pretty refined so it's a pretty good match, even if it has more power than you need. But it does give flexibility of you don't keep the speakers.

Well, you obviously had some thoughts about what you were purchasing right?  If you're happy with the equipment and feel the price was right then that's all that really matters and not what I or anyone else thinks.  Personally, I never make a purchase without an audition or two or three.  Good luck in your new home.  Celebrate it with a bottle of champagne and your new audio gear.

What the hell.  Go for it.  I've done something similar in the past.  It's your $$$$.  This is a crazy hobby, and you felt so inclined to put a system together the way you did, just because you could.  No sweat.  Anyway, if it turns out you aren't satisfied with any part of the system, you can always opt to return an item (if possible), or sell it on the used market.
