The analog THD+N was less than 0.017 percent at 1 kHz with a 100-millivolt input and the volume control set to 83.0. Crosstalk with a 100-mV input was –81.35 dB left to right and –83.60 dB right to left. The signal-to-noise ratio with “A” weighting was –124.15 dBrA.—MJP

Video Test Bench
The Marantz initially sailed through our HDMI benchmark tests when processing an HDMI signal with the exception of the Chroma Resolution test. The lower right box on the Spears & Munsil Benchmark disc showed some rolloff of the chroma signal culminating in a borderline Fail, but this deficiency didn’t rear its head in normal viewing material and only occurred when the Video Convert feature was in its default On position; taking the video processor out of the loop resulted in a Pass. As we finalized our review, Marantz investigated and sent a firmware update that fully resolved this issue, resulting in perfect video test bench scores across the board. The change is expected to be integrated wtith the AV8801's next firmware push. —DV

Here I am sitting with a great Integra 80.2 that is just over 2 years old and along comes a better sound processor. Then the reviewer admits it's better than his Integra 80.2. Man you are going to cost me money...retirement money no less.

Thanks for the review.

Hi David. Thanks for the review. The AV8801 does seem like one of the best pre/pros in the current market. I was, however, wondering if you noticed/found a great deal of sonic difference between AV8001 and AV7005. Thanks.

I haven't had an AV7005 in my room, so I can't compare the two. The AV880 does have MultEQ XT32 though, which is technically "better" than MultEQ XT due to more room filters and it should tame a bad room more proficiently.

Hello David,

How are you?

I need to ask for your kind support on my A/V SYSTEM UPGRADE, with your renown knowledge i hope you can help me out with this.

Thank you in advance for your kind attention to this:

I have the following system that i have been building over two years, i began with the Anthem MRX 700 but as the time were passing i started understanding a lot of which i did not know about the "audiophile world" and as it has been growing in CABLES, SPEAKERS, DAC, computer for audio etc etc. i began to get more involved with audio rather than home theater, as i feel that home theater is more easy to achieve than two channel audio.

1.- Anthem MRX 700 receiver as a preamp
2.- Crown XLS 2000 / 2 channel amp (using it in combo with the Anthem MRX 700 for my front speakers)
3.- Front speakers Golden ear Triton Two Towers (internally powered) (2 Power chords)
4.- Golden ear SuperSat 50c center
5.- Two Paradigm studio's 7 for surrounds
6.- Definitive Technology Super cube II Subwoofer
7.- Calyx 24/192 DAC (need to lower the noise)
8.- Oppo BDP 93 Universal player: for movies, SACD and DVD audio.
9.- MACMini for two channel music
10.- Transparent Music Link Super I/C's RCA
11.- Anti cables Speakers cables
12.- Transparent HDMI cables
13.- Transparent Power chord cable for Anthem receiver
14.- Ridge audio Street USB Poiema
15.- Panamax Power Conditioner

Note: My main goal to achieve: THE BEST "AFFORDABLE" TWO CHANNEL FOR MUSIC and a nice and good Home theater.

Choice #1

Sell the Anthem and get an audio preamp "The STP-SE from Wyred4Sound and two mono blocks from D-Sonic M2-600M 1 x 600 watts" and will work next to the Calyx DAC and my NEW Mac mini (SSD, 8Gb ram USB out put to Calyx DAC) with the rest of my system. And later get a good receiver or keep the Anthem.

Choice #2

Sell the Anthem and get a PRE PRO "The AV8801 from Marantz and two mono blocks from D-Sonic M2-600M 1 x 600 watts" and discard the Calyx DAC. and my NEW Mac mini (connected directly to the AV8801) with the rest of my system.

"MAYBE THE NEW KRELL FOUNDATION"

Note: "stock" Marantz AV8801 or "THE COMPANY UPGRADE" Marantz AV8801-SE??…From the David Schultz Upgrade it supposed to be in a superior level!

Best Regards

Miguel Casellas

Miguel, Thanks for looking to me for advice, but I'm not the best guy to speak to for 2-channel music. Outside of reviewing a product, I rarely will sit on the couch and listen to music...I'm a movie kind of guy. I suggest you head to Stereophile.com and ask Kal your questions because I think he's better suited in this particular case.

I was hoping to get your help. I currently have a hodgepodge system and am looking to get into a high end system for home theater. I currently have Kef Q7 floor speakers and Kef wall rears with a Def Tech Center and Sub. I am running a Pioneer Elite VSX-84TXSI receiver and B&W wall surround backs. (I know... Hodgepodge) I am looking at getting the following but need to buy it in pieces. What order should I purchase and do you have any recommendations?

1. Marantz AV8801 and MM8077 Pre-amp and Amp
2. Sonus Faber Venere 3.0 Floor speakers (front left and right) and Venere Center Channel
3. Rel R-528
4. Sonus Faber rears and surround backs (4 total)

Should I get the front left/right and center speakers first or the amp and pre-amp?

Your help would be most appreciated. I love this magazine!

Sorry for such a late reply and I hope you're able to read this. Unfortunately our system doesn't notify us when a new post is made in one of our reviews. As far as your purchase decision goes, I would get the speakers first since you will be living with them a lot longer than any source components you buy. In fact, my speakers are the oldest gear in my system by far and I doubt I'll be upgrading them for at least another 10 years. From there you can then test out amplifiers to find the one that mates best with the speakers, then move on to your pre/pro last. If it were me, I would go 2, 4, , 3, new amp and then 1.

I enjoyed the review, however I really would love to hear how it sounds with all eleven channels. I'm curious if it is an insane over the top waste of money or not. Maybe your better half would let you borrow some speaakers...

David, I have a 5.2 system with 5 Gallo Nucleus Reference Strada speakers and 2 Paradigm Seismic 110 subwoofers. The subwoofers have been set up with Paradigm's PBK-1 Perfect Bass Kit.

I am trying to decide whether to replace my Anthem AVM-20 with either the Marantz 7701 or the Marantz 8801 and I have a few questions that I am hoping you can advise on:

1. I don't plan to move beyond a 7.2 system, so the extra channels that the 8801 offers aren't of any value to me.
2. I understand that the addition of Audyssey Sub EQ HT will allow me to equalize and set the delay independently for each subwoofer. Since I am using PBK-1 and my subs are roughly equidistant from the listening position, I assume this is not something that adds value for me. Please correct me if I am wrong.
3. I understand that the upgrade from Audyssey MultEQ XT to Audyssey MultEQ XT32 is significant but that most of the significance is in the lower end. Since I am already using PBK-1, is this really worth more than doubling the price to go to the 8801?
4. Putting aside the difference between Audyssey MultEQ XT and Audyssey MultEQ XT32, is there a noticeable difference in the basic sound quality between the 7701 and the 8801? The price difference is pretty big, but I have been very pleased with the sound quality from my AVM-20 and would hate to be disappointed with whatever I replace it with.

Thank you very much for sharing your insights.

Sorry for the late response. In your case, I would try out the 7701 first and see how you like it. Buy it from somewhere that has a good return policy. In all honestly, the AV8801 is way overkill for my needs too, but I felt like splurging :)
