@moverton99 , the one higher up from the RX-A2A....i.e., the RX-A4A is what you may need with preouts for all channels. It is on accessories4less for $799, full price is usually around 1400.
Fidelity levels will improve depending on how hifi of a power amplifier you will connect to those preouts, especially the front stage (front left, center, front right).
Here’s a decent power amp candidate with 120 W/channel class AB, all channels driven, which should make your speakers behave...
Other things you could consider doing for your Yamaha receiver/processor...
- Read the manual cover to cover
- Turn off bluetooth and wifi. Don’t bother with the antenna.
- Hardwire/Connect with a ethernet cable, use a IFI ethernet filter before plugging in the ethernet cable.
- Use a Audioquest power conditioner such as the Audioquest Powerquest 505 or 707. Plug your processor, amp, router, etc into it on designated outlets.
- If you are a cable believer, use Audioquest power cables, speaker cables and ethernet cables (even the fairly affordable base models should be fine).
