can anyone address my SACD question & how it handles DSD in Direct mode? Direct to analog or converts to PCM?

Normally to PCM but in DIRECT/PURE DIRECT likely direct to analog.

In less than 4 years, I have had my 3008 fail on me twice (they bought back the first one and 2nd failed in 2 years). I have sweared now, I am not buying Onkyo anymore. However, I must admit, whenever it worked, I enjoyed its stereo music reproduction on 15 yrs old 3-way ADS .

Sounds like you've found your systems limit or at least the amp anyway.

Here are the pictures of the fans I installed to keep my 8801 and Parasound amps cool. They are quiet and work extremely well (although they aren't the prettiest things the world).

I don't know the distance or angle offhand.  The B&Ws are in the NYC system and the Marantz is in the CT system (as I am now).  In NYC, I use a Meridian 861 and/or an Audio Research MP1.

Dave, how do you have them 'triggered'?
Do they come on and off with the equipment?, or are they thermostat controlled?
(And they don't look too bad - recessed back a ways like they are...).

Yes they are...they move a lot of air and are very quiet.

Temperature controlled with one of these: http://www.coolerguys.com/840556093695.html

All told, I bought 4 fans and the controller for about $150 or so, but I'm only using three right now. I plan on adding the fourth to the right side of the unit to move additional cold air through the back of the unit, but I need to pull all the equipment out in order to cut a hole for air movement.

Honestly? Yes I would for the Marantz, not so much for the Parasounds. The HDMI boards in AVRs/pre-pros get much too hot for my liking, regardless of the manufacturer.

I have to agree, mines open on all sides and still gets to warm.

Mine is open in the front and back but the Parasound A51 is below which raises the ambient tempurature to the low 90's F.
That is enough to get the AV8801 up to 126 degrees in the back without a fan.
It does not take much to improve this. A 12V Gelid fan (that is 5 volts rated) running off the AV8801 rear port cools it closer to 100 degrees without adding any audible noise.



I tried Noctua and a white fan and for some reason, I liked the blue fan blades best.

126 is WAY too hot. I'm happy that I'm at about 96 degrees with the fan on. I'm thinking if I add one more fan blowing some air along the back of the rack I can lower the temperature another 5 degrees or so.

Hi all never had this issue before but for some reason I cannot get audyssey pro and Marantz to talk to each other anymore. I keep getting time out error or communication error something about turn off 2 way remote used. Anyone experienced this issue before?

Cheers

What I've noticed is that my AV8801 gets much warmer when processing DTS Master Audio 5.1, than it does when processing just regular old Dolby Digital 5.1 - anyone else noticed that?
(Compared when watching a Blu-ray at -10db w/DTSMA5.1, vs. watching CBL/Sat at -40db w/DD 5.1).
I don't know if the volume differences would make any difference in the heat generated by the AV8801(?), but maybe its outputting more voltage at the pre-outs, so could that generate more heat too?

I'm using a pair of 'CoolerGuy's 'blower fans that sit directly atop, and toward the rear on my AV8801:
http://www.coolerguys.com/840556094272.html
I have these triggered by a programmable CoolerGuys thermostat mounted in the amp cabinet below the AV8801, I have it come on at 87 degrees, and off at 80 degrees (though I vary the settings with the weather to come on sooner or later...).
I'll try and post the photo showing this:

Agreed but I will have to see what it is at these days.
BTW, I put a light dim on the Parasound red P and it tones it down for late night viewing tongue.gif

It's dealing with more bits with DTS-HD MA versus Dolby Digital, so maybe that has something to do with it.

Is it not possible to assign a video source while listening to CDs? I want to be able to watch DirecTv while listening to a CD via XLR. My DirecTv Genie can output HDMI & component simultaneously. I have both HDMI & component hooked up to the 8801. I tried assigning Component input 1 in the CD column in the Input Assign menu but there is no video. I was able to do this on my Denon 5308CI. Can I do this on the 8801 or am I doing something wrong?
