It's not that the Crown did or didn't help. It didn't really seem to make a difference but we aren't really cranking up the volume yet either. Just wasn't sure the crown was the right amp to get. DH thinks we're better off having at least a 3 channel amp. And since I'm the one that decided to upgrade our fronts, center and the sub, I'm not going to tell him that we don't need to also protect the center channel with more power. Because I really don't know if the 2 channel was adequate or not.
Upgrading the AVR is not just about extra power, it's also (primarily) about new sound formats I don't have, and the convenience of wifi and bluetooth built in. Also, at some point we want to put in ceiling Atmos speakers and want to have that as an option we don't currently have. Right now, it isn't absolutely necessary and it might even be better to wait until next year when 2.2 hdmi capable receivers come out. But if we don't upgrade, then Im back to looking at amps just to ensure we have adequate clean power to run 9 channels.
As far as what's lacking... I'll get back to you after we get the new sub

I'm basically just trying to get the best system we can afford and future proof as much as possible, because this is probably the last time we will spend any significant funds on the home theater. Priority after this is planning for retirement in 12 years.
Sounds like you are a good candidate for the outgoing (you mentioned budget is not unlimited) Denon top model, the AVR-X7200WA.
https://www.amazon.com/Denon-AVR-X7200WA-Channel-Receiver-Bluetooth/dp/B00XIG6LYC
At the current price of $1800, nothing can touch it. It has the latest sound format, Audyssey Platinum for room equalization, top AK4490 DAC (digital to analog converter) that is the same one used in the newest $4,500 Marantz AV8805 processor and the $4,000 Denon AVR-X8500H). Like the comparable RX-A3060, it has been bench tested by S&V to produce the following power output into 4-ohm loads.

Two channel driven continuously into 4-ohm loads:
234.7 watts at 0.1% distortion
265.5 watts at 1.0% distortion
Five channels driven into 8-ohm loads:
122.3 watts at 0.1% distortion
138 watts at 1.0% distortion
Compared to the Yamaha RX-A3060, Denon has better looking distortion vs output graph, much lower cross talk, and marginally better signal-to-noise ratio. The Denon also has much better 5 and 7 channel driven outputs.
The AVR-X7200WA apparently has a "real" pre-amp mode because according to the online manual (scroll down to the end).
http://manuals.denon.com/AVRX7200WA/NA/EN/BIAJSYjhudqdih.php
"This stops operation of the internal power amplifier of this unit, reducing interference in the pre amplifier created by the power amplifier."
I don't believe it will improve sound quality, but it might improve it's reliability and longevity when used with a multi-channel external amplifier. I would still add at least one $10-$20 Infinity fan to help cooling it for even better longevity. This applies to just about any recent models of any brand.
With this flag ship AVR, you can definitely use a 300 WPC external amplifier to drive the big 95f only, or use the AVR in pre-amp mode by adding a Monolith 7 channel amp.
The bottom line is, your HT room, the big 95f, and the LSI9 deserves much better than the anemic RX-V863.
