Denon 4520CI + 4806 combo as pre-pro and power amp

I just recently bought an used pair 4520CI+4806 combo which previous owner used as pre-pro/power amp combo. Also, previous owner mentioned that 4806 amp section is better than 4520CI and that's the primary reason for using 4806 as power amp while using 4520CI as pre-pro.

Based on my research, it seemed like 4806 is one of the best Denon amp - beefy amp, power supplies, large capacitor etc. ( other than 5805 of course) and thought it would be great setup as audiophile friend of mine used Denon 4308 as pre-pro with NAD T773 receiver as power amp and NAD has power amp inputs other than regular 8.1 EXT inputs and it sounds great.  Based on checking with my friend, in case of NAD T773 setup, it looks like there is no involvement of volume control on power amp inputs in the receiver but it looks to me that's not the case for 4806 based on looking up online so far.

So here are my questions:

I primarily bought this setup and considering used as I can't afford 7200WA right now but wanted high end sound and that's why purchased used. Secondly, I'm also right now not really interested in setting up Atmos( but 4200W is on fire sale with 5.1.2 setup and is tempting though) for now but at the same time wanted best sound quality for both music and movies. My listening preferences includes 50% music and 50% movies.

1) Is it really worth the pain of setting up 4520CI as pre-pro and 4806 as power amp?

First of all, is this setup really recommended? Also I'm not sure if 4806 really supports power amp mode similar to NAD T773 or not. If it isn't then is this setup really valid/recommended? It's confusing as both are receivers and have volume controls in both 4520CI and 4806.

If this setup is valid, then can you recommend what are the setup steps involved in setting it up in both 4520CI to configure as pre-processor and 4806 as power amp?

2) Secondly, is it going to be any better than what's out there such as Denon X4200W which is on fire sale and also there is a great deal on Denon X6200W

4200 has discrete amplifier and is close to 28 pounds
6200 is close to 30 pounds with mono block power amp construction.
4806 is really heavy around 52 pounds and 4520CI 36 pounds similar to 7200WA with L/R separated mono block power amp construction.
4520CI amp is very similar to 7200WA as both are mono block construction with L/R separated except 7200WA has upgraded DACs

First of all I'm not sure if the amplifier differences between 4520/4806 to 4200/6200 are worth it? I don't really listen at high volumes but at moderate volumes and my speakers are rated 4 ohms.

I did not find really rave reviews on 4520CI other than usual Denon 4.5 stars review from Sound and vision which also provided 4.5 stars for X4200W as well. Does this mean they both perform equally well?

For 4806 there are lot's of good reviews out there raving about sound quality and internals:

Last but not least, I appreciate your help and based on your replies I'll either keep this combo or may want to back out the deal if it's not the right setup as the seller did not provide accurate info on the setup so far and moreover the seller is not going to ship until early next week and I may have to to ask my money for refund(worst case).

Thanks.

Thanks for your feedback. I'm buying 4520CI + 4806 as combo offer as the previous owner used it that way and mentioned that 4806 amp sounded better than running it off from 4520CI. So, previous owner usage was 4520CI as pre-pro and 4806 as amp and I wanted to continue doing so as well.


The real question here is using 4520CI as pre-amp and 4806 as power amp is actually valid set up or not as 4806 doesn't have separate power amp inputs as NAD T773 and this means I have to use 7.1 analog input in 4806 which means volume control is involved in both receivers which is confusing

Thanks for your input and clarifying that 4806 as power amp is just a stop gap and not a great option. Since seller has not shipped it, I’ll cancel the transaction instead of reselling 4806 to avoid hassles.

I’m not sure if I need power amp at all and happened to go that route based on this transaction as seller was offering pre-pro, power amp combo deal. Since I never had separates before, I did not know if this was right setup and thanks for all clarification. So, in the future I’ll buy separate power amp as opposed to stop gap solution.

I’ll take time to think about revamping my home theater with good warmer sounding power amp such as B&K or purchasing audiophile quality AV receiver such as Anthem 300(which I just auditioned used one today locally and it seemed to sound great but still has only one hdmi output ), Cambridge Audio 651r is available online for great price as well.

Moreover, I already have Sherwood R972 which sounds great but doesn’t have bell and whistles like Denon 4520ci like even basic HDMI CEC and has only 1 HDMI output but trinnov is fantastic.

Thanks for AVR 850 suggestion but I'm on budget and that's the main reason I originally thought this combo would work but backed out due to non optimal setup and stop gap as suggested above as two volume controls are involved. I'm currently looking at lower model of CA selling for $449

Thanks for showing the internals. Yes, I do have Totem speakers but it's running fine with Sherwood 972 and I don't want to invest a lot and wanted one simple solution for both audio/video still sounding good for music as opposed to separates. How about Cambridge Audio 651R instead? It costs almost double but I don't want to spend more than that.

Yes, I'm also concerned with the quality issues of refurbished. So, I'm still keeping my fingers crossed for some holiday deal.
