AVR vs PREAMP! | Marantz SR7015 v IOTA AVX17 | Dolby Atmos |

[@hatoraidcowboy]

I have an Anthem MRX 720 receiver and I use it as a pre-out with a 7.2.4 configuration. Anthem ARC genesis is by far the best room correction software I have used. Channel separation is incredible. Side note: Just watched Jurassic World: Dominion and OMG, best DTS:X track BY A MILE and might be my new #1 fav object based audio mix over Godzilla vs Kong.

[@ealanosborne]

[@josealfredfernandes]

First! In short: Seperates all the way if you need better quality.

[@IECStang]

Thank you so much for making this video. I currently have an x3700H in pre amp mode right now with my 7.2.4 configuration and I was wondering how much better a dedicated processor sounds versus an AVR. When you said that you could feel the sound make your skin twitch that's the kind of detail I'm looking for. Plus I want that awesome channel separation you get from a dedicated processor. For the longest time I could never find a video on youtube that matches an AVR in pre amp mode versus a dedicated processor besides one of Youthman's videos he did on seperates but he just didn't go into the amount of detail on the sound differences between the two, so thank you so much for finally going into more detail about the subtle sound details that you picked up on. I will be getting a Tonewinner At-300 as soon as I save up for one. Thanks again Ealan Osborne. You have the best audio,video, and music channel on KZbin in my opinion. Keep up the great work! :)

[@ealanosborne]

OMG, thank you for your incredibly kind words! So glad that this helped as much as I had hoped it would help others. 😁🤘

@@ealanosborne Finally got the Tonewinner AT-300 and it sounds amazing!!! There is a big difference in speaker separation and the tone of bass. Before the bass on the AVR was there it just wasn't detailed like it is on the Tonewinner. With everything having its own place it sounds so much better. Thanks again Ealan keep up the great work!

Great video! Lots of good information! The Marantz 7015 is on clearance at Best Buy, do u think it’s worth upgrading to it, I currently have a 7011 and have a Sony A9G, and a 7.2.4 setup. I have had no issues with my 7011. Just no Auro3D. Thanks in advance.

[@ealanosborne]

Thanks for your kind words! :) The 7011 is still an incredible AVR even today, but I guess if you're a gamer, it might make sense to upgrade, with HDMI 2.1 support, QFT, ALLM and VRR for an ultra-smooth high-end gaming experience. That and the 7015 can have all internal amps completely shut off in "preamp mode" so it sounds JUUUST a little bit better if you had a plan of eventually getting into separates and slowly acquiring external amps. Other than that, I'd probably just stick with the 7011. :)

[@rayking507]

Hi there, does the Iotavx sound fuller and with more authoritythe than Marantz SR 7015 for mid frequencies.

[@ealanosborne]

I personally think so, IMO. The dialog seemed to cut through a bit more clearly, or pronounced with the IOTA. 👍

[@TylerStout]

I bet a lot of the issues you ran into with the Marantz are related to bugs/suboptimal design decisions mainly the bug where they have been setting ALL the distances of your speakers wrong by a certain factor due to conversion errors (note this is fixed with the MultiEQ-X). I can find you the link if you need. Then the optimal target curve of Audyssey isn't great hence why you need the app imo. However I am curious as to why you thought that bass was better on the IOTA. I wonder if that was just they have that channel hotter or the pre-out on the IOTA has higher voltage or something. Also worth noting generally the built in test tones are not using the calibration so if you level match with db meter using them you might actually but unlevel matching so my recommendation would be to use REW or a test tone disc with the benefit of REW being that you can control the frequency range of the pink noise which makes a big difference for subwoofer pink noise. But yeah everyone talks about channel separation and object placement so that was my expected improvement you would hear.

[@FURognar]

Yeah the distance bug is a big one. But apparently doesnt effect all models. We havent been able to figure out when it started to take effect. I would expect that the new AVRs and processors coming out will not have that bug (its more of an error than a bug though)

[@doublet147]

I'm curious as to why you set the LFE to 80hz. The LFE "channel" is audio engineered to 120hz & below.

[@rogernafziger3051]

Thanks for another great video and keeping me on track through the rabbit hole. I’ve convinced myself (and my wife, more importantly) to upgrade the Onkyo TXNR686 to separates and a 7.2.4 setup in our 15x18 dedicated theater room. The decision now is Iota AVX17 or TW AT300? Is the AVX worth the extra $$$ for the additional channels? How does their room correction compare? It sounds like you weren’t disappointed with AVX17 room correction, which was good to hear. Thanks, and keep the great videos coming!

[@ealanosborne]

Thanks! I think one thing might night be a dealbreaker is that the AVX17 doesn’t support eARC. So if you utilize that feature a lot (like using your smart TV apps or have a PS5 connected directly to your TV) I’d stick with the AT-300 maybe

[@ealanosborne]

I plan on reviewing those soon! Just FYI, take a look at the dimensions and weight. They’re bigger and heavier than you think! 😄 But that’s a good thing. I’ve had them as my front wides for some time, but when I officially review them, I’ll put them as my front L/R to really listen to their output. But if you do mount them, I’d make sure to screw them onto a stud (if at all possible) because they are solid! 🤘

[@demonreturns4336]

Someone that uses Front Wides My kinda guy 👍

[@monijam1]

Separates are generally better if one can afford it but a good AVR with efficient speakers in a space that isn't too large, crossover set to 80hz, with dual or more subs will produce very enjoyable sound. For Denon & Marantz I suggest turning on Dynamic EQ to bring back the bass. If you do this the low end will return in a big way or you can use the new Audyssey MultEQ-X software upgrade to tweak the sound just the way you want it! Only downside though is the software is $199.99.

[@JonMoralesLA]

Some of the Denon and Marantz speakers are getting Dirac Live support in March 2023. For example the Denon 3700h and 4700h models. This is a paid firmware upgrade with two tiers…$260 and $350. I don’t get what the difference is in tiers. So if anyone is thinking about upgrading it might be better to hold off on Audyssey paid upgrade and wait for Dirac Live support in March 2023.

[@billybobby7607]

Setting subwoofer to 80hz means you are losing the 80-120 on the lfe channel. Unfortunately it won't direct it to other capable speakers it just chucks it away

[@colinmcauliffe5205]

thank you

[@PorasChaudhary]

Awesome videos man!! One question though.. Can I use my AVR (or AVRs) as an amplifier if I buy an AV Processor?

[@ealanosborne]

Typically only the more expensive AVRs that have the “7.1 analog input” section can pull that off. 😬

[@chebrubin]

Andrew Robinson uses a Marantz SR8015 and it is probably more superior to the Marantz SR7015. But for sure the IOTA AVX17 and Tonewinner are the most exceptional separate platform for 9.x.4. I completely agree with your conclusion. You have nailed the current state of separates vs. receivers differentiation. Don't get caught up in feature checkboxes and crying over HDMI v 2.1 8k inputs or you will be spending millions on a processor while you should be investing in speakers and amplifiers for the long term. If you are listening to 4k Ultra HD; don't waste time with room correction etc. either. These things are mixed so well that your separate amplifiers and speakers will sing with the IOTA AVX17 and Tonewinner.

[@chebrubin]

@P T Um no.

[@alecpulianas6919]

I was leaning towards separates when assembling my home theater (mainly for Spacial Audio) and then AVR and now I’m back to separates! Haah

[@ealanosborne]

I get it! There are pros and cons for both. 😄

[@rayking507]

Hı there, I can’t make up my mind. Iota with external amp or Anthem without external amps. They will cost similar if you consider the cost of 7 channel external amp for the IOTA. Many thanks.

[@ealanosborne]

I'd probably say go for Anthem if you listen to music a lot too through your home theater system, since it's better for that. And Anthem AVRs have more features like 8K video support, etc. So if you want better future proofing, go with Anthem. Although there is a rumor that IOTA is developing an 8K/HDMI 2.1/eARC version of the AVX17 with Dirac Live that will be released in 2023. So there's something to think about if you want to wait for awhile.

[@rayking507]

This was brilliantly done Ealan. I'm about to switch to full externally powered speakers with my X3700. I have two old rotel power amps. It has been a journey. Although I did invest in audyssey mult eqx for the Denon. Did you use this version or the baked in version of Audyssey on the amp? I also feel like Audyssey is a bit flat and it needs a good bass bump. Dynamic EQ does a decent job of lifting the bass and punch at lower volumes too.

[@ealanosborne]

Yeah, the baked-in version. I wanna get MultEQ-X eventually, just to see and witness all the hype. :)

@@calibre00 I'm genuinely curious. Still waiting on delivery of my second rotel amp (second hand RB985). Is the 3700 in full pre amp mode different sounding?

[@calibre00]

@@wayneiceman Im convinced that it is, the amps inside the X3700 have been measured to be very clean sounding but in pre-amp mode with good amplification this goes to another level, things are not strained in any way when the scenes get really hectic at high volumes, best way to describe it is the clarity you get from the X3700 at mid volume, is available at reference levels. Also depth of sound took a big step up, as of recently I run my front stage in full range now (as Audessey Xt32 recommend) and you could actually go without a sub, as it gets low and sounds effortless. I don't of course 😃 Ealan did a video about first time going to external amps with an avr, I think what he describes is very accurate to what I experienced also.

[@pauledwards8721]

Great comparison. Would be interesting to get some REW sweeps of the bass issue you were seeing with Audyssey, I bet the timing was off on your subs and you had some cancellation. My Denon does this in my space, quite dramatically, I have to manually adjust my sub delay to get proper dual sub integration (even with native dual sub output).

[@engseong857]

What’s your opinion on running separates if I’m only intending to have a 5.1 or 5.2 setup? Would it be worth it when considering both price and performance, would the benefits outweigh the costs overall?

[@ealanosborne]

I touch on that exactly in my 2022 Wish List Video. Now that more people are getting into home theater, there needs to be more options - 5 channel preamps, or 9 channel, as opposed to 13 or more like it is now. I would always suggest separates, since the balance of power and audio processing is unmatched compared to all-in-one AVRs.

[@LeeLee-fi7mx]

Would be interesting to see a comparison between the Iota and a mid to higher tier Denon AVR used in pre amp mode as Denon's usually measure better and have a reputation for sounding better for movies than their Marantz counterparts.

Curious about the bass, I know most SPL meters struggle to get accurate bass readings and REW with the UMIK would probably get you better SPL readings.

I am leaning toward either Antem AVM70 with ARC or Arcam AV41 with Dirac.

Seriously. I have yet to have a good experience running Audyssey. I know MultEQ-X is supposedly leagues better, but the fact that you have to purchase it on top of your initial AVR purchase is silly. Dirac Live and ARC are fantastic, and come included with many AVRs and processors nowadays, so Audyssey and/or Denon/Marantz need to address the issues with their included software.
