Have the Marantz SR7007, should i get the SR7009?

I have this setup: Klipsch RF 62 II, RC 52 II center, RS-52 II as rears, SVS PC-13 Ultra and Marantz sr7007 receiver.

Would I benefit in getting the SR7009, seeing it offers more watts per channel? Sure, you never get the advertised amount. But in the end, will my sound benefit from it?
Not interested in atmos, just power my setup wich admitedly sounds really good.
Any help would be appreciated.

There is no difference in power as they are both 125W/CH, rather the upgrade in audio quality would come from the much more advanced Audyssey MultEQ XT32 in the SR7009.

Your subwoofer is a beast and those speakers are known for being efficient and go loud with little power.
More power would only benefit at very high db levels at that. Adding an external 2 channel amp would be plenty
and free up a few channels for zone 2 if needed.

I wouldn't spend $1,500 just to get xt32 over audyssey xt. Your receiver is good/modern enough.
Instead spend $110 for a minidsp external subwoofer eq. It will perform as good as xt32 and yes xt32
is a lot better than xt. Study this post for proof of that. "Official" Audyssey thread (FAQ in post #51779)
http://www.minidsp.com/products/mini...ox/minidsp-2x4 cheapest true subwoofer eq.

It will take a few things to measure the room and setup the minidsp properly. About $125
Room eq wizard software. Free http://www.roomeqwizard.com/
A good usb measurement microphone. $75 http://www.parts-express.com/dayton-...m_campaign=pla

boom style mic stand http://www.monoprice.com/Product?seq...FQGRaQodInIAJw
long hdmi cable from receiver to computer http://www.monoprice.com/Product?c_i...seq=1&format=2
And a laptop with hdmi out. Once the subwoofer eq is adjusted properly you may want audyssey xt off at times (music).

And you can use this same hardware with any future stereo setup. Your subwoofer amp may have an eq built in.
You still want the measurement gear to adjust it. Single frequency test tones are tedious, inaccurate and slow.
If this doesn't improve the sound buy better speakers next.

I was under the impression they increased it to 200 per channel, but I guess thats just marketing talk.
I Dont consider Xt32 worth it...

Thats a great idea! So an external amp to power the two towers? Not the center?
That would leave more juice for the other speakers.
Do you have any recommendations for a 2 channel amp?
Also how would I connect it to the Sr7007?

You can upgrade your SR7007 to XT32.

Sorry, but not possible as the AVR must come with it built in (eg. SR7008 and SR7009).

The Emotiva XPA-2 would be a good choice. Simply connect a RCA cable from each of the FL/FR pre-outs on the 7007 to the XPA-2 (or other external amp).

I believe the SR7007 got XT32 via a firmware update. Marantz never had any XT32 products before that.

Again ... the SR7008 is the first Marantz AVR (aside from AV8801 pre/pro) to get XT32 which is not currently firmware upgradeable. The SR7007 uses XT. It did get a firmware update to add 24/192 kHz gapless FLAC/ALAC and Spotify.

They make nice external amps 1 channel(monoblock), 2 ch, 3 channel you name it. Three channel amp is fine. No need to use more than that. Emotiva makes every configuration. Plenty of external amps around here. Used is a good way to buy. Regular single pin rca cables for each channel and 1 minijack cable for the trigger(on). This will put less strain/heat on the receiver and play clean slightly louder. Last step after amp is eq the bass(below 80hz) better.

Would the XPA-200 be enough for the two front towers? https://emotiva.com/products/amplifiers/xpa-200

If you don't mind the industrial look the Crown X2000 amp is on sale for $199.
450W x 2 @ 4ohm, 330W x 2 @ 8ohms.

What do you mean with eq the bass below 80hz? Personally I never set the eq on the sub. After the audeyssey run i've set the crossover for the towers, center and surrounds at 120. Any suggestion is welcome.

I have the SR7008

also w/ RF-52's - RC-62 & an SW-110

- no complaints - hope the Atmos will be able to be as a firmware update someday =) ! (doubt it)

- if ya think ya need more power use this one first - use 85-90 % - set it to 60-70 during loud action movies and when playing blue ray music or HDCD I use 80-90 when home alone -or when the g/f aint around =) ..

a buddy just got a SR6008 and he said whoa for 5.1 & music compared to his ~10 y/o Onk.. & he runs a higher end speaker set up


I was on the phone with Marantz customer service before pulling the trigger - long n short - guy said any of the recent 700X series - you won't notice a tonality change or power change - therefore no sen$e in the update imho - are you happy with playing mp3's from a thumb drive ? I am - it opens it right up for me ... expands the sound w/MDAX

I am chomping at the bit to get front wide, front height or rear height speakers next - may try to stay with RF series Klipsch, may try a mock up of 9.1 with my different sets around the house to see if I like it first (set of Paradigm 3se & Infinity bookshelves)

I thought I could live w/o internet connectivity - but not many nights have gone when I spend some time I just listen' to free HD internet radio something music as I read - a library of music from a remote -- amazing compared to the 70's 8 tacks and 45's

Marantz has bass auto eq through audyssey and no manual subwoofer eq adjustment. Most brands have some manual sub eq. To do manual eq accurate measurement of frequency amplitude must be done first. Either by a sound meter with single frequency test tones or better yet a full range sweep with rew software. Measure your results of bass eq and it probably isn't very flat. I started out by downloading 5 second long wav files of single frequencies from 14hz to 90hz and loaded them on a usb stick. Play those in order and document maximum db of each tone. They will vary. Some may be way louder or quieter than others. The room size/shape/surface covering have a big influence on the bass frequency db level. That is why eq is needed. To level out the loudness of all frequencies. Audyssey xt only does a little of that. Xt32 quite a bit more. Manual eq even more until bass db measures almost equal from 14 to 90hz.

Most of the sound improvement from the 7007 to the 7009 is better auto room eq from xt32. That is it. A lot of money just for slightly flatter bass eq.
Until you measure the room it is tough to tell the actual quality of sound the receiver is outputting. REW allows you to create a graph that converts to an image that can be attached here. Post your results and we go from there.
