A head-to-head av receiver comparison to help you pick the right one for your room.

Verdict
The step from the X1800H to the X3800H buys better room correction, more channels and more inputs, at roughly two and a half times the price. Buy the X1800H for a 5.1.2 system in a normal room; buy the X3800H if you are running more channels, multiple subwoofers, or several 4K 120 Hz sources.
X3800H sold out; now sold as the X3900H, under $2,500
Now sold as the X3900H: Check Price| Denon AVR-X1800H | Denon AVR-X3800H | |
|---|---|---|
| Room correction | Audyssey MultEQ | Audyssey MultEQ XT32, far more resolution |
| Channels | 7.2 | 9.4 |
| Subwoofer outputs | Two, same signal | Four, independently managed |
| HDMI 2.1 inputs | Three | Six |
| Pre-outs | Limited | Full |
| Best for | 5.1.2 in a normal room | Larger systems, multiple subs |
The table above compares the Denon AVR-X1800H and the Denon AVR-X3800H on room correction, channels, subwoofer outputs, HDMI 2.1 inputs and pre-outs, and the difference that actually decides it is the subwoofer rows, two outputs carrying the same signal against four that are managed independently.
Audyssey MultEQ XT32 is Denon's highest room correction tier, which measures the room with a microphone and builds correction filters at far higher resolution than standard MultEQ, most of that resolution landing in the bass where rooms do the most damage.
You are building a 5.1.2 system, you have one subwoofer, and you have one or two high-refresh sources. It does that job properly and the money saved buys better speakers.

You want independent subwoofer management, more than seven channels, or you have several consoles and a PC feeding the system. XT32 is also a meaningful step up in correction resolution.
Now sold as the X3900H: new X3800H stock is no longer available on Amazon. Denon has replaced it with the AVR-X3900H, which keeps the 9.4-channel layout, 105 W per channel, Audyssey MultEQ XT32 and four subwoofer outputs, so everything above about the X3800H applies to it. The buttons on this page go to the X3900H.

Yes, particularly in the bass. It uses far more filter resolution, and the difference is most audible exactly where rooms cause the most trouble.
Only if you run more than one subwoofer, but then it matters a lot. Independent management lets the receiver time-align and level-match each one, which is how you get even bass across several seats.
Often, yes. If the choice is the cheaper receiver with better speakers or the better receiver with lesser speakers, speakers usually win. The exception is a difficult room, where correction earns its place.
