Worst electronic product we have ever owned. We can not adjust the sound without being able to hear the peoples voices when we try to watch a movie. The remote control eats up batteries so fast it is hard to even use it.

Very disappointed

Purchased from JSG Audio Johnson City NY

Marantz sr 870,what a deal it is,this unit beat the hell out of the vector research vr 7000/Marantz sr5000,not to consider other many different units i had for 30 years,this thing is a monster in stereo mode,i haven't try 5.1 yet,but with audiophile's system i'd hear before,this unit isn't any less if anything it's more,the low draggs out and very smooth,the high is crispy,don't hear any distortion,unbelievable

Very good Dolby Pro Logic mvie listening and excellant remote control. The on screen displays are excellant.

The music portion is very weak. The highs are not crisp and midrange is weak.

When I purchased the Marantz 870 I was really interested in the Home theater aspects. It rocked the house and with the multi room funtion we crank up the niles speakers outside. The Marantz is a little flat in the music end and I just purchased a Yamaha RX-V3200 with a little more power 120 per channel and better rangel of listening modes. The Yamaha sounds so much better, but I miss the RC-2000 remote.

Currently have a Yamaha RX-V3200 and I am very satisfied with the replacement of an old friend.

Superb construction. Warm, natural sound. 110 watts to each of the front channels. Direct 6 channel inputs for Dolby Digital.

Only 75W per channel in the rear could be considered a weakness by today's standards. I found the surrounds to have ample power for any surround effects.

I've recently retired this receiver after over 4 years of faithful service. I've been extremely happy with this unit. It's performed flawlessly and the quality of this particular line of Marantz receivers is quite high. Manufactured in Japan, this receiver is a beast, built like a tank with huge internal components and more than enough power for anything I threw at it. I found the sound warm and inviting and the onscreen screens easy and useful. I also especially liked the ability to provide two video signals from each hookup, for example, I could hook up svhs and composite video outs to different components at the same time. The new Marantz midrange line (5200 - 7200) will not do this which I found a bit disappointing since not all my vcrs are svhs. The remote is the original RC2000 which is one of the best remotes built in the last several years. Buttons beat touch screens anyday! Overall, a great value and excellent performance from a quality name that stands above most competitors. Let's hope the Denon merger doesn't screw things up!

Clean power, great remote

Remote sucks batteries

I bought this as an audio/HT compromise and have been extremely satisfied.

For music, I would recommend using the 6-Channel direct mode which by-passes the tone controls. The sound is much cleaner.

For HT, it is DD ready and has excellent sound and features in Pro-Logic.

If you're DVD player has a built in decoder or you have an outboard decoder, and you want a step up from Yamaha and other mass market junk, check it out.

Recently purchased marantz sr780 to go w/ csw movieworks 5.1. After purchaseing hk avr 20 mk2 , then sony strde 915, then hk avr 75, I finaly found a reciever that had enough back end to satisfy my dvd palyer (sony dvps 500). The remote is exceptional and the overall imageing reproduced by this reciever is unmatched by anything else I have heard. Even when switching between Rotel separates and sr780 the difference was minimal. The price difference was about $3000.00. The rotel products were not $3000.00 better maybe $300.00.

Ease of use

Bought this reciever to upgrade my rather old pro logic sony and have used it as a base to start an upgrade of my home theatre:

Toshiba DVD SDK-320
Polk Audoi RT8's + Polk C220 centre
Cannon Dome speakers for the rears (yeah - who's heard of these ?)
Marantz CC-3000 CD
LFD Spiro III interconnect
QED Qudos cables

I really have no complaints and compared to my mates $5000 Naim system I VERY happy with the sound I have achieved for the dollars spent. The Polks are a little too rich in the Bass but it seems clean enough. Have difficulty relating to the 2 very poor reviews posted for this reciever - and can only assume that is is being compared to something vastly out of it's range, which is not really that fair. Lets compare apples with apples and not a VW Beetle to an Audi TT.

This reciever had been a great product. I originally wanted the SR-770 but fora couple hundred dollars more you get a significant increase in power,
especially to the surround channels and that complex remote control. I also
was looking at the Denon line but choose the Marantz because I thought it's
warmer sound would be a better match for my Def Tech bp-8's. The Marantz
has pre-outs for all of its channels. I don't think the pre-amp section is all that
terrible good. It sounded raspy with an Audire amp hooked up to it while a
dedicated Dayton Wright pre-amp sounds much better. I do not have this
problem when just running the Marantz by itself. This reciever has plenty of
power and will supposedly drive low impedance loads. It drives my BP-8's and
B&W's to extremely loud levels. It has acceptable bass output but tends not to
be all that tight. The mids are a bit warm and the highs are detailed but not
irritating. I do not get fatigued from listening to this reciever. The reciever is
large compared to my old pioneer and required a hand saw to get it in my
cabinet. It runs cool when compared to my pioneer vsx-453 which I beleived it
was possibly to fry an egg. The remote is heavy and eats battery's. But makes
a great conversational piece. This reciever is a great alternative to expensive
seperates and gives close to separate performance with music and
hometheater. Listen to a Yamaha, Denon or Marantz before you even
consider one of the others. My VSX-453 totally turned me off to Pioneer.

This is the worst receiver I have ever heard. It is a cross with Sherwood, HK, and Candle. Why would anyone buy this ?

Fantastic Sound, easy to use, very powerful.

Came with Marantz MKI remote. Remote is great except that if you program it to work all of your other components, it can no longer work the SR-870. Surround power is lower than it really should be.

This replaced Adcom separates and was my first surround-sound receiver. The sound quality is great. Very "laid back" which makes it an excellent match for my fairly bright Klipsch KG4 front speakers.
