I am already wired and have speakers connected for 11.2, maybe will have 11.2 for Xmas!!!

If this was a 'DHC' model I'd be inclined to bite...

Maybe there's also peace of mind that you know you're getting two components that were designed together and in theory should be a perfect match.
As for the talk of plastic, I currently have a PM-15S1 (one of their reference series amps), and I honestly can't tell if it's plastic or metal. The material on the cheeks looks matte, whereas the front panel is more brushed aluminium. It kinda looks like plastic, but feels cold like the aluminium next to it. Maybe it's some kind of fancy paint injected plastic. My unit is in Champagne-gold, which I think makes a difference to the plasticy look. I saw the AV7005 and MM7055 (in black) in a store and immediately noticed the difference. What also didn't help was where people had left finger nail marks on the plastic bits. I guess I'll just have to keep a cleaning cloth handy to keep it looking nice smile.gif

Yeah, I guess it feels like I cheaped out, but I didn't actually know what speakers I was getting when I bought the amp, and I've been quite happy with the performance. I've also been thinking of picking up a Marantz PM11S3, just for the R/L, but I worry about having uniform amplification for the front three channels.

DenonLink does work especially with MPCM BD, DVDA and SACD playback.

I understand you said "version", my comments were in jest smile.gif. No doubt D-Link works but doesn't HDMI work with those formats as well?

Yes but the consensus among DL users is that for packet based formats that need to be decoded inside the pre/pro the gains are not there. The reason is that no time info is 'used' from the player.

Quality amps are linear. This means their outputs are always a fixed multiple (their "gain") of the input signals, no matter what the input signal's voltage is -- unless the amp clips, of course. Once you've successfully run Audyssey's calibration, all of the active speaker channels will produce exactly the same sound level for the same input signal, no matter what the gain is of the individual amps. Audyssey compensates for the gain of the amp in each channel by changing the gain in that channel's preamp.

Some amps do have high enough gain that you have to include attenuators in the signal going to those amps in order to perform a successful calibration. This is indicated by a level of -12db or lower for channels with excessive amplifier gain.

HDMI works but jitter is pretty high

Using the DenonLink for DSD/DVDA or for clock signals work pretty well for MPCM data. I still use my 4010/4810 combo for multichannel SACD/DVDA and BR music.

Is the jitter when listening to SACDs and DVD-As with HDMI that audible that it can be obviously heard? Or is the difference in sound quality between HDMI and Denon Link just a measurable specification that is not clearly heard when comparisons are made?

Thanks for the heads up y'all! Finally!

I still feel we aren't much wiser regarding sound quality. Take the talk about XLR: we all know XLR connections are good and reject noise. But is the friggin' stereo input a superior path comapred to the one in AV7701 or not?

Also, the fact the amp is "shallow" isn't very usefull if you need to add two more stereo amps for full blown DSX/Neo:X.

No matter how you arrange them, you'll need at least two boxes to have enough amplifiers to drive 11 channels. A 7 channel amp plus a 5 channel amp would be one possibility, leaving one channel unused. It seems to me that having more than 7 amps in a box can only reduce the wattage available for the individual channels.

The small footprint is useful because my TV stand does not accommodation 20" depth amps without purchasing additional extenders to place on the back of the stand. It will also push the stand out another 4-5 inches into the room.

Not if you build a bigger box. Yamaha Z11 had 11 amps, even if four (Presence) were only 50 Watt.

Not if each amp channel had it's own power transformer, like the older sherbourn amps.

Bill you can search the Denon 4010 thread for comments on DenonLink. I'll try not to go too much OT here. Unlikely you'll find much ABX blind test data there tho, if that's your cup of tea.

You could get something like the W4S ICEBox where each channel can be configured separately: up to 7 channels and each can run at full specs. And maybe another MiniMC with 4 channels.

The pix of the new pre pro do make it look like a beast!
In looking at the back/business end of the new unit, it has, in addition to a ton of HDMI, 4 Ethernet and a USB connection.

The USB connection interests me, as I play my music through an HTPC. Right now music and video,over HDMI, which, I am told, is jittery due to lack of a dedicated audio clock.
Is the USB connection going to be a digital audio input - possibly dejitterizing my audio life?

I've never seen any. A quick google search only came up a picture of the 7005 and pictures from this thread.

Usually it's the Chinese and Japanese websites that crack open the lid and take photos of the internals, but the 7701 hasn't been launched in this region yet.

Maybe you could ask politely in the 7701 thread if they could. smile.gif

Hmmmmm been waiting for this one.
Been wanting a true 11.2 channel Pre/pro for a while now.
Here comes the wides and heights. Yippee
Marantz and Triad get ready for my money.
looking forward to the reviews as those of you lucky enough to live in the US get your hands on it.
living in Australia, we always get things like this much later on or if at all

Don't know about the 8801, but try the Oppo 105 coming out soon to play your HTPC through USB taking advantage of their awesome DACs for the sweetest sound ever!

Wse, if you have some music CDs, try playing them in yr BR player over HDMI and over coax. The coax invariably sounds better even though both are digital and feeding the same DAC.

I find if you use bitstream data, the jitter isn't a big a problem because the bitstream needs to be decided and reclocked first. Tends to affect PCM.

There was lots of discussion and tests on the avp/poa thread (sticky) searching that will keep you busy and you can also ask its a relaxing crowd inside smile.gif

Awesome! Thank you! Ill add them to my folder of amp guts.

The first thing I noticed is how empty the 7005 is in comparison. At least we're getting a lot of extra hardware for the money

Also on the 8801 and Denon 4520 they both have a small daughter board above the hdmi board with 3 CPU / DSPs and some flash or ram chips. Maybe these are what's needed to run the xt32. Either that or 9 or 11 channels need significantly more power to process.
