AV8805 Decision

We are building a new home and the A/V installer recommends the AV8805. I feel that it is overkill because I have a Parasound A-51 Halo amp that is only five channels. What will i gain from buying this vs the 7705 or even a Denon AVR?

Probably nothing if all you interested in is a 5.1 system. A 7705 will support up to a 5.2.4 IMHO

hey!

I just bought an A51 this week from a forum member and I, too, am trying to decide if I want a Denon 8500/6500 or a Marantz Preamp for my 5ch setup I will be running in my new home under construction.

Definitely following this thread so please keep up updated!

Nothing firm, but most likely the AV8805A HDMI 2.1 hardware upgrade won't be available until next summer 2020.

Hopefully the update enables all 16 channels of the chassis for Atmos, since Dolby made that Firmware available and the hardware is capable of it.

Or even the Marantz SR7013. [IMG class=inlineimg]/forum/images/smilies/smile.gif[/IMG]
But does the 8805 use the upgraded DAC that is also in the 8500?

This 8805 is literally double the price of the 7705.

Sonically speaking, there isn’t a difference in sound between the 8805/7705?

Yes, as both are considered the current "flagship" Denon/Marantz models.

It(8805) was a definite step up from the 7005 for me sonically but i dont know how the newer 7705 version compares. Hopefully someone else know them both well and can answer.

This is the reason I wont buy a receiver for more than 500 dollars, no matter how many bells an wistles it has. We live in a throw away world. Get something a year or two later upgrade it or use it till it dies, throw it away get a new one, It is just the world we live in. Most everything made now is not made to last. High dollar avr's are made for people with alot of money, they can afford to throw them away.

I've used my Parasound A51 with a few AVR's and pre-pro's since I bought it. It's been paired with a Marantz AV8802A (essentially a AV8805) for the last three years now, love it! You can update your system (adding additional amp's and speakers) as you need. But the AV8805 (or AV8802A) combined with Parasound A51 is a superb sounding set-up for music and movies

Well said my friend , My A21 has seen three marantz pre/pros and one Anthem. The 8802a and 8805 with the Halo amps are a true one two punch excelling at both movies and music

I have a 7704 and I am wondering the sound difference if upgrading to an 8805. I have been staring at this for a while and would like to hear what members think 7704 vs. 8805, or would a 7705 be just as good of an upgrade. EQ is in my signature. Thanks!

The sound? Who knows?

The AV7704 and AV8805 have very similar designs. The main advantage of the AV8805 is two additional channels. Unless you need the two added channels moving from an AV7704 to an AV8805 IMNVHO makes little sense.

The AV7705 has a couple small upgrades from the AV7704 and AV8805. Normally the AV770X series has some of these small upgrades every year. If you owned say an AV7702, the sum of the upgrades to the AV7705 could be significant. One year of upgrades not so much.

One upgrade is that thin film 1% resistors are used in the AV7705 vs. thick film 5% units the older two units. This upgrade should reduce noise and distortion, and improve the output quality of the DAC area. These are improvements to areas that are already very good so frankly they are unlikely to be heard. The other upgrade is removing one capacitor per channel that wasn't required. This might make a small difference in sub 10Hz performance, which is really less than a nit.

2020 will, should, may, might, whatever, see HDMI 2.1 implemented in the AV8805(a?) and next version of the AV7705. You might want to wait to see how HDMI 2.1 implementations shake out before you buy anything. An upgrade to HDMI 2.1 is promised for the existing AV8805. This upgrade at a service center will cost money and take the unit out of your hands for a period of time. New versions of the DAC IC's in the AV8805, AV7705 and AV7704 have been have been introduced by AKM since these AVP's units were introduced. Again, not a big deal, but if you want to have the latest and greatest the next models may satisfy that need.

Monoprice promises a new AVP with 16-channels, Dirac room correction and the latest AKM DAC IC's, the Monolith HTP-1, for $4k, to be available in the late September - October time period. Almost everything is sunshine and roses with the unit at present, since it isn't actually available!! The HTP-1 is another option once the unit is actually introduced, and after a shakeout period to sort out any problems. The Monoprice Monolith subs and power amps have been good so there is a lot of interest in this unit.

https://www.monoprice.com/product?p_id=37887

https://www.avsforum.com/forum/90-re...processor.html

Bottom line recommendation: The AV7704 is an excellent unit. Stay with it for now.

Huh? The 7705 has upgraded and better transistors compared to the 8805...?

All I know the 8805 has the 5db better SNR AKM DAC, 2 more channels, and Made in Japan.

On a related note I am trying to figure out how the 8805 costs literally twice as much and how I could justify the cost difference for my new home theater. It can’t sound twice as better, right? I’m only going to run 5.2.4 with Parasound A51 amplification to Energy RC-70 fronts, RC-LCR, RC-70 rears.

It's not twice as good...after about the $1000 mark, your value drops as the price goes up you only get minimal improvements for a lot more money--it's called the law of diminishing returns.

I own both. I use the 7704 for my upstairs and the 8805 for my theatre room. I did a side by side comparison and was surprised that the 7704 held its own.

Bottom line, if you have highly detailed speakers and play uncompressed music you would likely enjoy the difference. I have not heard the m&k’s that you have but based on the reviews they seem worthy of the best. Of course, if hdmi 2.1 is important to you, waiting till next year is sound advice.

While the AV8805 has more channels, the benefit is not the more channels but other quality features it has over the 7705. I get price is a factor.

Even if you don’t utilize all 13.2 channels the 8805 being made in Sound United’s reference Shirakawa factory in Japan is the beginning of the story. This factory is reserved for the AV8805, Reference 2 channel gear (PM10, SA10 etc) Denon 8500 and the new Classé gear.

The 7705 is built in Vietnam.

The 8805 starts with a Toroidal power supply, this feeds 4 large capacitors. 2 of those are dedicated to the 15 HDAM modules, 1 per channel. The other 2 caps are for the rest of the unit.

The 7705 has a single PCB for all the channels instead of an individual PCBs per channel like on the 8805.

The 8805 also has 8 stereo DACs, 1 DAC for every 2 channels, instead of a single multi channel DAC like on the 7705.

The 8805 DAC is optimized for the front L&R channel, and then copied for all other channels in pairs with the additional DACs.

The 8805 has a dual core processor.

Among other features such as the copper plated 3 piece chassis, there are several reasons the 30 pound 8805 is 2x the price of the 23 pound 7704/7705.

8805. See the 15 circuit boards behind the display. Those are the 15 HDAM modules. 1 per channel.

7705. Notice the empty space? The extra 8 lbs in the 8805 didn’t come from no where.

And in addition to all of this, the 8805 has a multi-level “Dialogue Enhancement” feature where the lower models utilize a (similarly named) feature that is just a simple center channel boost. They’re not the same thing.

If HDMI 2.1 is brought into consideration (which for some, it will, and others, it won’t), then you’d have to replace the 7705 to gain the HDMI 2.1 features. With the 8805, this upgrade will cost a couple hundred dollars and, yes, have to go back to a service center to complete.

I don’t know if I’ll ever need HDMI 2.1, but I never rule anything out. I debated this idea myself, then this thought came to mind... I could buy two 770x processors for the same price as the 8805, but they still won’t be the equal of the “flagship” model.

In the end, I’m happy that I made the decision to go for the 8805. To my ears, and in my system, the 8805 does sound fuller, more detailed, and all around better than the 7703 it replaced.

If price is a consideration, the 8805 can be purchased well below MSRP from legitimate “authorized” dealers. For one of them, you don’t have to go outside of this forum to get a great price.

If you were blindfolded, would you be able to tell if someone had put the 7704 in the main room? And, if so, how dramatic would the difference be? Notice immediately?

Thanks for the mini review! happy to hear that the 8805 to you sounds better than the 7703. i Just sold my 7703 last month and got a 8805, didn't have time to take it our the box yet but should be up and running sometime in September.
