new receiver suggestions

[hardcore_gamer99]

Ok so i had 4800h and had to sell it for some reason. I want to try marantz this time. I will be powering up dali rubikore 6+ rubikore centre channel+ opticon 2 mk2 as rear pair and 4 atmos speakers. Someone said we can only select 6 and 8 ohms in settings but all these speakers are 4 ohms only will it work? Also Can cinema 40 not do 7.x.4 without any amp? Also i am getting denon x6800h for 2.13lakhs INR and this cinema 40 for 1.75lakhs but cinema 30 is very costly here 2.75lakhs INR. How should i proceed?

They all can power those speakers but how well each AVR will perform with them will depend a lot on:

1) seating distance
2) your listening habit, such as how long you listen to

For example, if you sit 4 meters vs 2 meters from the speakers, you will need roughly 4 times the output from the AVR than what you would need if you sit 2 meters from them.

If you listen to reference level (cinema loud), versus say 10 dB lower (still very loud for a lot of people) below reference, then you will need 10 times the output from your AVR.

For those so called 4 ohm nominal speakers, if you want to play safe without considering what your actual requirements are, then go with any of the X4800H, Cinema 40, X6800H, Cinema 30 but add external amps that are rated 200 W 8 ohms, 300 W 4 ohms.

From "power" output stand point, if you are going to use power amps, even the X3800H or the Cinema 50 will still be adequate.

The Denon versus Marantz topic seems popular on forums but in reality the difference is just aesthetic so highly subjective by nature. Other than that, some people believe Marantz use their so called "Soundmaster" to tune their devices to sound warm and musical, but there is no scientific basis, but mostly something created by some very smart marketing people. People who are subjective oriented, don't understand too much about the underlying science and bench test measurements will tend to buy in to such smart marketing talks, as they are good at providing a lot seemingly good reasons for why Marantz has that "signature" warm and musical sound. My suggestion is, if you can get the Cinema 30 for just a few hundred dollars, such as up to $400, and you like the better look, and perceived better build quality, then go for it, if more than say $500, and the X6800H looks fine to you, then save the money for something that actually matter, but again, that's just my opinion.

cinema 30 here is 3200 usd =2.85lakhs INR and denon x6800h 2400usd. Id i have to use amp then i dont think i need these models. i have small room length is 13 feet but i have habit of 70 volume. Even cinema 40 is 1982 usd here

The x6800 and Cinema30 both have 11Ch Amp, so both can do 7.1.4 ATMOS without needing any additional amps.

X4800 and Cinema40 have 9Ch Amp.

As far as the impedance switch setting try this article https://www.audioholics.com/audio-amplifier/impedance-selector-switch-1

why 1000 usd difference then for x6800h and cinema 30

why 1000 usd difference then for x6800h and cinema 30

There are many reasons, that include the following:

- X6800H and C30 has the more expensive, much better DAC chips
- Two more power amp channels
- Slightly larger power supply (especially the C30)
- 13 channel processing, that's 2 more than the X4800H and C40
- Gold plated RCA connectors

Of the above, the only reason that I prefer the X6800H and the C30 is the better DAC, but in reality, most users will not likely be able to hear a difference between them and the X4800H, X3800H and the C50.

The difference in power output is almost meaningless, especially if you use external power amps for the front 3 speakers.

The difference between the X6800H and C30, for Euro 1000 is, in my opinion, ridiculous. The difference between the X3800H and the C50 is around Euro 300, and Euro 200 between the X4800H and C40 at least in Germany and France, that seems reasonable.

If you don't only need 11 channels processing, and you really prefer Marantz, then I would recommend the C40 or even the C50, and add a 3 channel power amplifier for the front 3 channels.

Assuming you don't sit more than 2 to 3 meters from the rear and Atmos speakers, the AVR's own power amps should be able to drive those speakers and if the AVR runs a little warm, a Euro 20 fan on top or blowing from the rear will fix that for you.

Personally I would still go with the X6800H because of the DAC but that's just me, as most people don't believe the better DAC IC would make any difference, and I believe they are smarter than me on that lol..

Power amp need: I would recommend it because if you need to turn the volume to 70 when using the X4800H, you could be pushing the AVR amps close to the clipping point during peaks in the contents. The resulting distortion will not likely be audible but for a few hundred dollars more, get a 3 channel amp to help the poor AVR.

Not so sure that is true. The improvement I am getting from my AV 10 is stunning. I like everyone else thought speakers were the weakest link and that improvement in electronics would not be noticeable. Well my speakers were not the weakest link by a long shot. Those AV 7705 and 7706 AVPS were and by miles.

Those previous AVPs did not get the best from my speaker system. Not close. Yes the sound was very good, but now it is absolutely phenomenal. I am going to start another thread after listening to the 76 plus concerts from the 2025 BBC Proms, and last night was yesterday. An absolutely amazing experience.

You think there might be a difference in SQ between the X6800 vs X3800?

why 1000 usd difference then for x6800h and cinema 30

Sound United used some different parts that cost more for the Cinema30 vs X6800.

Just one small example- the Cinema30 chassis likely cost more than the x6800 chassis. There are other internal parts differences between the 2 AVRs.

Also, at least in the USA, the C30 has a 5 YR warranty and the x6800 has a 3 YR warranty.

So they are very similar, but there are differences.

Or why would

I think it would depend on what speakers it would be connected to. You have to remember I am using some of the very best drivers that are made today, and not in China, but Norway for the front three. Obviously there are a lot of speakers I have never heard, but I have heard some very costly speakers at dealers and they are not close to mine in accuracy. I do know that B & W 800 D3 speakers well, widely acclaimed as a one of the best speakers available and they measured very well. These were my late friend Phil's. However, Phil thought mine the better speakers. One of the big reasons is that they are TLs, so the bass is deep and incredibly accurate and free of coloration. No ported or sealed speaker can compare with the bass accuracy of a well designed TL. This allows the mid and HF to not be obscured.

What I can tell you is that I have just listened to all the BBC Proms over the last two months, 76 form the Albert Hall alone. The thing that really stood out to me was the HF details and impact. In a concert when the cymbals are employed with a very hard closure the effect is dramatic, but until this last couple of months I have never heard them reproduced with such force and realistically. In addition violins are a tough instrument to properly reproduce. Yet with this AV 10 the string sections are totally realistic. The trumpets and trombones are also reproduced with extreme realism. The same goes for the BPO streams on the digital concert hall. So I would say that the dramatic improvement is towards the upper end of the frequency spectrum

I think one of the issues that makes these improvements discernable is that the TLs have such an accurate uncolored bass, so the higher frequencies are not obscured.

This improvement is not slight or subtle but striking. This came as a total revelation to me and was not something I expected or anticipated and there is no doubt about it. But I will take it as a very pleasant surprise.

I was really annoyed that I had to go through the hassle and expense of purchasing the AV10 and the hassle of installing it. This was especially true as I thought my listening experience would not change. But the impact of this change in equipment has not lessened over time. So I now regard those AVP failures as pure good luck, as it has taken the listening experience from my speaker to a much higher level.

This is incorrect. All the B&W 800s D1-D4 have been shown have a big spike of about +5dB around 10kHz.

I have posted FR graphs from Stereophile reviews on this subject multiple times.

Now if your in-room FR measured better than all the Stereophile measurements, that’s one thing. But their FR did not look great on Stereophile, S&V Magazine or Soundstage.

But their aesthetics look great to me.
