If someone asked on this thread for a 7.1 speaker system recommendation that could be ran to reference level with only a high quality AVR to avoid the need for an amp, I would say

3 X Noesis 212
4 X S8
2 x OS or S2

I think I inadvertently started up an amp debate when I was only asking for specific thoughts on just the 8077 since I'm getting a combo deal with the 8801, but you're absolutely correct about not needing an amp, hence my reasoning to get CD/horn speakers in the first place.

I really wanted to get the 7008, but when that troublemaker Archaea tongue.gif stepped in and reminded we need to have a 4 ohm avr to be safe, that scratched the 7008 of the list. And the next sexy marantz unit with xt32 and 4ohm stable is the pre/pro 8801, which of course requires an amp.

Obviously, many have had no issues running their 212 with non-4ohm rated avrs, so this is the only question that needs to be verified...is it inadvisable to run off anything other than an officially spec'd 4 ohm avr? Or are we just as bad as those who use two prong converters for their three prong plugs? wink.gif

1) There are plenty of AVRs certified for 4ohm loads, and there is probably a legitimate reason the others are not.
2) Just because one person makes it work with one model of AVR - doesn't mean a different model from a different manufactorer will.
--2b) Carp what model Pioneer Elite do you have? Can you see if it's certified for 4ohm?
3) Coolgeek's experience with the 212HT is an example. Used a Martantz not rated for 4ohm and it didn't work well at all, made him think he needed to use a high power external amp. Got an Onkyo rated for 4ohm and couldn't tell the difference between external amp and Onkyo.

I turn in my vote for don't do it --- or at least call Marantz support and get their opinon.

I must stress the gen2 though as the gain on them is 29dB vs. the 32 of the gen1's which most have had issues with running 212's and running into the Audyssey trims being maxed out trying to attenuate the Noesis enough. The 29dB gain will help with that.

Thanks Brandon...Emotiva is my favorite go to amp for the best value. I'm only considering the 8807 because I'm getting a very good deal on a combo. I'd have to buy 2 emo's and that's where the 8807 combo is making more sense with just the numbers for now. If I don't go with the 8801 or 7008 is confirmed as not a good idea with its non-4 ohm support, then it seems the 4520 may be my best option.

I did a quick google search and looks like it is rated for 6 ohms? Not sure if that's right though. It's the elite vsx-53.

For me the hiss from the speakers is much more of a negative than knowing I can go to 10-15 over reference more cleanly than the avr. So, as mentioned before, I think the way to go is having an AVR or preamp with XLR outs to avoid the dreaded hiss that seems to always happen with rca to xlr.

I had a Pioneer SC-37 and SC-57 that worked just fine with the T12s. Pioneer just isn't as attractive to me any more B/C lack of sub EQ to price. But they are powerful none the less.

Any of these AVRs will work great with JTR speakers:

Denon X-4000 & 4520 Onkyo 1010 3010 5010

Just stay with top end models and most major brands should work great. I like the Integra 80.3 pre-pro and dtr 80.3 AVR but it is really the Onkyo 5010.

Chris

The amp vs No amp debate has been going on in this thread for years and I must say I am becoming less hard headed about actually needing/wanting an amp then I was 2 years ago. biggrin.gif
Amps cost so much less and are so much more powerful then they were 5 years ago that I cannot pass on them.

Maybe we can get Nathan to come over with his speaker/amp switcher so we can do some a/b perspective testing.

Jon's video of the 1 watt on the 212's painted the picture, but it's still really cool to experience it in person.

Might save you some money.

Options...options...

For sure. We must R&D for the greater good. And after that impressive display of arm wrestling abilities, I could use your powerful strength to move these gargantuan boxes into the dungeon wink.gif

I absolutely love my 8801, but after the SB and the new Danley's come in, I might be looking into something else in the near future. I love the XLR support, but I don't really like what audyssey does, and want to try out some of the other room correction systems out there. The Anthem mrx-710 with the new 1m corrections system has caught my eye. No height or wide support, which I don't need, and no XLR, but definitely worth a look. I might sell the 8801, but not until I got the Anthem and tried it out first.

Brandon,

What is your opinion on the new Emotiva XMC-1? It's looking pretty good to me, but I'd hold off on purchase until someone verifies it isn't bug ridden.

Dirac Live room correction? Anyone know anything about that? I wonder if you can just auto eq up to 300hz ish and turn off the eq above that.

That would be my number one concern with Emotiva. They build fine amps from what I have read but their last pre/pro launch did not exactly go smooth. My guess is it will start out buggy and take months to get "right" or maybe never quite get to "right" ever. The DIRAC is intriguing but I would not put myself at the front of the line. Pre/pros are incredibly complex to build with today's technology. I have read the Anthem D2v board and the Krell Foundation board and those have been out for a while and still have issues. That is one of the big reasons I ended up going with the 8801.....seemed much less buggy and XT 32.

You know this is now going to become an ARC vs XT32 debate tongue.gif

I think I want to stick between Denon or Marantz. Otherwise I'll be researching every other model for the next month. Oh crap. I'm already googling the mrx-710...look at what you've done!

That is the one that intrigues me the most, but I couldn't have said it better myself. It comes out, no bugs, or minimal issues, and allows some type of app control, You'll see one in my rack in no-time.

I believe JapanDave uses Dirac Live in his space with one of the standalone units, so he could maybe comment, but the REQ options seem to be very robust.

What the THX certification means is that the AVR will cleanly play any commercially available program material to reference level in the relevant sized room and listening distance when driving 89dB/1W/m sensitivity speakers with a minimum impedance of 3.2Ω (4Ω nominal). This assumes bass management of all satellite channels at the THX 80Hz crossover. In theory then, with the Noesis 212HT's hooked up to a THX AVR you will have around 12dB of headroom (or 16x power) at reference level.

For the XT32/THX Ultra combo with nine amplified channels, I would check out the Onkyo TX-NR3009/3010 models and their equivalent Integras. In my opinion, there's little to be gained for the price of going to the Onkyo 5009/5010 flagships.


Thats interesting, I have always thought of my 3600 ^3 HT room as medium sized. Maybe it is a large-tall. tongue.gifwink.gif

All this AVR is more than enough talk makes me more confident that my W4S amp at 1100WPC will drive the 215's. I was really close to pulling the trigger on an Lab Gruppen 10000Q but the amp talk here made me think it was unnecessary. I also considered the clone amps based upon the price but I was told that the 110 version on a 20 amp circuit only puts out approx the same watts as my W4S.
We shall see...

Opinions are not facts.

Hehe. That's what I am here to do smile.gif I don't want to spark the aud/arc debate, I just want to make my own supported opinion on it biggrin.gif I have never heard any other REQ other than audyssey, and can poke my fair share of holes in what audyssey does, so I want to venture away from that type product. If standalone units were available cheap, I would never consider selling the 8801 and just add-in smile.gif

http://emotivalounge.proboards.com/thread/35357/secret-warehouse-sale-starts
priced posted include shipping and a lot of these amps are 80+ lbs - so it's a little better value there.

The XPA amps are just as good as anything I've experienced out there personally and often come in a bit cheaper -- though not sure what you've got lined up on the marantz combo...
The XPR are supposedly a bit better --- but I'm not a believer it even matters after some of the amp testing we've done in KC.

These are nice amps - but there are other amps for sale on the list too. My Generation 1 XPA-3 was a nice amp I thought and worked well with my 228HT.
XPA-3 Gen2 FR - $650 (3 channel)
XPA-2 Gen2 FR - $700 (2 channel)
XPA-5 Gen2 FR - $800 (5 channel)


To each his own...

From what I have read in this thread :Emotiva amps create an even bigger problem with JTR because they have such high gain ?

The Gen1's are the problem, where the gain is 32dB. The Gen2's they dropped to 29dB so that helps a little.

Geez, here I was thinking I have a small to medium room, and it turns out I'm a Large. Huh. Who woulda thunk?

Your logic makes sense, but unfortunately, many AVRs are not THX Ultra2 Plus certified (likely because they don't want to pay the licensing fees if their specs already meet or exceed THX). The only manufacturers that have Ultra2 Plus certification are Onkyo, Integra, Pioneer, and one Yamaha. I passed on Onkyo based on their less than stellar reliability reviews in the past couple of years and the Pioneers didn't appeal to me. For me, the Denon and Marantz seemed to have overall great reviews and plenty of features built in.

My Gen 1 XPA-3 worked fine with the 228HT powred by RCA off my Onkyo TX-NR1007. Trims were set to about -9 or 10 in my room. Mains and center are about 10 feet away. Probably wouldn't work with the more senstiive 212HT. with the additional 3dB down for Emotiva gen 2 I might have got away with 212HT okay in my room. Put XLR pre-amp output in the mix and probably not without attenuators (in my room anyway) because XLR sends a bit stronger voltage output than RCA typically.

Another option is to buy a stack of four Crown stereo 1000 or 1500 pro amps. Several of the guys in the recent PA meet have ventured this direction, and some of the crown amps are complely silent until they reach a certain heat threshold which is to say the fans will never turn on for home theater use. You might pm Gorilla83 or ChopShop1 for their recommendations there.

Unique Squared sells Crowns on ebay and more importantly takes offers. (often at significant discounts from what I've read on the forums. A half dozen people got Inuke DSP 3000's for $240 in buy it now offer for instance in one of the DIY threads, and those are $360 - $400 pretty much everywhere else)

Ah.smile.gif

The Anthem MRX-710 has received high praise for its stereo performance from members on our local HTforum.
Compared to XT-32 ARC also offers insight in the results and limited custom adjustment.

On Denon vs Marantz : Denon is considered to be a bit more dynamic where Marantz is more laid back.
I have not listened to the Denon but can attest to the Marantz sound.

$$$$
http://emotivalounge.proboards.com/thread/35357/secret-warehouse-sale-starts
XPR-2 FR - $1,500 *ships via LTL freight. U.S. only.
XPR-5 FR - $1,900 *ships via LTL freight. U.S. only.

At that point I'm pricepoint hard to ignore the stack of Crowns. biggrin.gif

I'm also a fan of the yamaha p_s series
http://www.yamahaproaudio.com/global/en/products/poweramps/ps_series/
Dead silent until they hit 90*c at which point the amp's fan spins up. In my use of a borrowed unit the amp's fan never turned on. Quality built, everything about them reeks of quality compared to many amps I've laid my grubby hands on.

Unique Squared sells Crowns on ebay and more importantly takes offers. (often at significant discounts from what I've read on the forums.

The guts in the xls1000 I would steer clear of. The 1500 and up have much improved power supply boards and more meaty components. I am currently using a 1500 to run the line sources and it works beautifully. Not a peep out of it.

On Denon vs Marantz : Denon is considered to be a bit more dynamic where Marantz is more laid back.
I have not listened to the Denon but can attest to the Marantz sound.

Full ARC allows a ton of customization. The full implementation is in the D2V and 50V. The MRX 710 improves the ARC over the MRX700 but it still is a limited ARC implementation. I spent quite a bit of time reading up on it over the last few weeks as I was looking at the D2V. Nick said the D2V will receive no more updates which implies no 4K upgrade. That was a dealer killer for me as I wouldn't spend that kind of money unless it had some legs for the next few years.

XPR-5 FR - $1,900 *ships via LTL freight. U.S. only.

At that point I'm pricepoint hard to ignore the stack of Crowns. biggrin.gif

I'm also a fan of the yamaha p_s series

Dead silent until they hit 90*c at which point the amp's fan spins up. In my use of a borrowed unit the amp's fan never turned on. Quality built, everything about them reeks of quality compared to many amps I've laid my grubby hands on.


How can we help you spend your money today? tongue.gif

Ha smile.gif

Those prices are even cheaper than their holiday sale, which is *supposed* to be their best sale. Apparently the secret warehouse sale is better.

I had grabbed a screenshot during the holiday sale to compare just for this reason:


All jokes aside, the XPA Gen 2 is plenty and the best value for most who want to try amps.

I am using two Crown XLS-1500s (bought from Unique Squared smile.gif) to power the 212 LCRs and the quintuple back surround. The fan NEVER turned on in my setup.

Amps are only needed if the AVR can't drive 4 ohm speakers with enough power. Sound quality should be the same on all unless something is wrong.

Marantz 7702 Atmos
3 Inuke NU4-6000 amps for all speakers.
Speakers- 7 Behringer B215XL's, 4 212xl's for ceiling speakers.
Front subs 12 SI 18ht ported SLLT powered by Inuke 6000
Rear subs 2 XXX ported SLLT powered by IPR2-7500.

Everyone at Cedia used the Datasat Rs20i for demos. It has the full version of Dirac Live. And I mean everyone. The Emo has a limited version and I'm very curious to hear the input from the early buyers.

--2b) Carp what model Pioneer Elite do you have? Can you see if it's certified for 4ohm?
3) Coolgeek's experience with the 212HT is an example. Used a Martantz not rated for 4ohm and it didn't work well at all, made him think he needed to use a high power external amp. Got an Onkyo rated for 4ohm and couldn't tell the difference between external amp and Onkyo.

I turn in my vote for don't do it --- or at least call Marantz support and get their opinon.

My Pioneer receiver isn't 4ohm rated and I was able to drive my 228HT's and four QS8 surrounds extremely loud and didn't have any issues. But as soon as I tried raising the levels on the surrounds to level match them to the 228HT's, it would cause the amp to shut down after about 20mins. If I would raise the levels on the surrounds it was perfectly fine.

Now that I have a PA 7-350, I have no need to worry about that.
